I PMd Lemonie a load of ideas for his next picture quiz, to follow on from the last one. It appears that it has fallen to me to make this one, with patches as prizes to be awarded by me, or by Lemonie if I run out. So.... Here are the pictures, they spell out the names of active instructablers. Post below if you think you've worked one or more out, see the previous thread if you're unsure how this works! 1)Dinner Jacket + Radioactive + Ronnie James Dio m/ - (congrats NachoMahma) 2)Fungus under a microscope + (a) + Mung Beans + Universal Studios - (congrats Hiyadudez) 3)Lithiography + Podium + Grain = Lithium Rain 4) Jeff Hardy + Cherios - (congrats Lemonie) 5) Nacho + Mother Teresa (Mahma) - (congrats Thermoelectric) 6) G-Wizz + Michael Jackson + Lord Howe Islan - (congrats gmjhowe) 7) Sun in a Jar + Snowbanks - (congrats Nachomahma) 8) Fake Troll = Froll + Yard Sale - (congrats gmjhowe) 9) Nine Inch Nails (NIN) + Zirconia + Mr Bean - (congrats NachoMahma) 10)

Free picture-quiz! (Isn't this site great...?) Some of you will know this format, others will not. The pictures "spell-out" Instructables user names, either literally or with a bit of thinking. The first is me as an example, the other 10 are the ones I'd like to see a full set of answers for. While this is just for fun I'll patch whoever gets them any of them. While I don't expect people to do this, it would be preferable only to post answers to all10. So far: 1 Red KITE MAN tractor unit 2 ANGRY RED (Fraggle) HEAD (from Full Metal Jacket, where as Marines the toilets were referred to as "Heads" in line with marine terminology) 3 CAN IDA (an asteroid) 4 JAY (E) and Silent-Bob FU (U) Manchu as played by Boris Karloff 5 JESS (Postman Pat's cat) (Y) RAT Barton FINK 6 KENT (county) (S) OK (magazine) 7 (=) S & M ART Garfunkel (=) 8 GOO Tenacious D Tony HART 9 (THE) (Breakfast) BURRITO The MASTER (from Dr Who?, as played by Roger Delgado) 10 Mr BUMP US flag The winners being NachoMahma, Kiteman, n8man & Jayefuu L

I can not find the quiz....

Hey guys! Im back with another Knexer's Quiz 3. You may, or may not remember the last two quizzes, as they were around 4-5 months ago. Anyway, here is a link to the past two quizzes, check them both out first so you get how to answer each picture: https://www.instructables.com/community/Knexer-quiz/ https://www.instructables.com/community/Knexers-quiz-2/ Also, please only answer ONE picture, as it is not fair for others who want to play. As of once again, the first picture is me, as an example. Hill + Yard sale + Dudel + (Z)                      (Hiyadudez) ? Eye (I) + American Idol + Canadian           (Congrats Stale56) Florida + 2nd Place + Burning man          (Congrats to DJ Radio) ? ? ? Owl City + England + Monday                     (Congrats Knexguy) ? ? Good luck, and happy guessing!

Hi there, I own a pub and write what has become a very successful pub quiz with a twist.  We'd like to take it to the next level with the creation of a buzzer system for the teams.  It would need to be a buzzer system with at least 12 buttons (preferably more)  and I guess that it would best if it were a 'lock-out' system.  Is it possible to create a reliable and relatively inexpensive system?  we're UK based when it comes to parts buying.  Thanks in advance!

I couldnt copy and paste it, but my score was 170 out of 200 aspie and 30 out of 200 neurotypical. just leaving this info, sorry no pic of the results.

I'd have them making fire but i think it would contravene health & safety.....

Knexer quiz. You may have seen a few of these before, done by Lemonie and Jayefuu, but I just couldnt resist making one for the knexers! I do ask one thing of you though, if you know more than one of them, please only answer one, to give others a chance, thanks :-) Every picture represents a well-known knexer, can you guess them right? :-) Sorry guys, but there are no prizes :-( The first picture is an example on how to solve these, it says hiyadudez, and the answer would look like this: Hill + Yard sale + Dudel + (ez) Now some may be quite difficult, but some may be very easy. I will say it again to be clear, I ask one thing of you, if you know more than one of them, please only answer one, to give others a chance, thanks :-) 1. Hill + Yard sale + Dudel + (z) 2. Where Dutch people live + World War 1 + Lord of the rigs (Congrats Knex mad) 3. Shad + Mow  + Man + (39) (Congrats Shadowman39! 4. Oblivion rollercoaster + iTunes (Congrats LaserJunkie) 5. Goo + Train (Quite easy but congrats Motaboi) 6. Iron + Man (Congrats Knexfan9182) 7. Killer whale + Safety hat + Nutcracker (Congrats Knex gun builder) 8. Knee + Exilim + Free to dance + (K) (Congrats Perkinator) 9. Chocolate log + Ice cubes + Buoy (Congrats Dsman195276) 10. Love + Down + Eye (Congrats Killer~safecracker 11. Good luck!

Are you a walking encyclopedia of all things instructables? Or do you not know beans about the site? You don't have to wonder anymore-take the awesome quiz!Then post how you did here! EDIT: I forgot to add, after you view the results, the correct answers for all questions are displayed, along with mildly witty comments. So you do find out who it is who really likes hawaiian shirts. ;)

I want to make a set of quiz buzzers so that, for example: someone asks a trivia question and two other people have a button each, both connected to a sound and/or light buzzer. The question is asked and as soon as one person hits their button and makes their buzzer and/or light come on, the other person's button then does nothing until the other person's light and/or buzzer has turned off. (Basically, only one light can be on at any one time) I have searched various sites on how to build one of these, but they never tell you how to make it like the title of it says, they just have links on the site that let you buy their product. If anyone has any idea on how to make this work, then I would appreciate any ideas you have. Thanks for your time.

Hi all. my church has task us youth to design a quiz buzzer lockout system type of thing to be used for a bible quiz. so the host will ask a question and 8 people will try to be fist to press their button... the fastest button will lockout out all 7 other buttons so they wont buzz... after he answered then the host will press a reset switch and continue with the next question... i did a ton of research and always end up with arduino arduino arduino... and the instructions is all for 4 or so people and its not very clear to understand or easy to do. i know a bit of programming so that wont be a challenge. i love electronics so that wont be a problem. i just need a clear set of instructions to follow and some guidelines and parts to buy... (im 14 years old... )  the quiz is end of march. it for 8 people cause 8 youths of 8 different churches will compete.  if anyone could give me a plan or guide or point me in the right direction that would be super !!! i know im gonna need some wire... allot of wire... and an arduino... thanks in advance to all you wise folk :) oh btw i live in cape town...

Hey whats up the names Jason. I am 13 and like to play with computers but not like Halo (although i am guilty of occasionally playing Halo) what interest me is computer logic and programming. So right now i am half-way decentish with Qbasic and consequently Visual Basic, but the language i am most fluent in is just plain old DOS scripting (batch files). My math teacher at the begging of the year my math teacher announced that once o twice a month we would have a pop quiz on square roots and squares of numbers 1-20. Now to say the least I am poor with memorization. So i tried flash cards and starin at a sheet with the squares and square roots on it. but I was pretty consistently getting 60s and 70s. Now being a pretty good student this upset me and my parents weren't exactly happy. So then i decided i would make a batch file to quiz me on this, my first one was on sqrts. writing this took forever so even still i made another for squares. These programs help me study immensely and i now get a perfect 100 every quiz.. i then started thinking that there must be a way to speed up the writing of a simaler quiz program. thats why i wrote this, and i know it is probably mediocre but i like it so be nice. (You can do whatever you want with this source code, and while not required i would prefer credit if you distribute a mod of this batch file.)Here it is:rem The purpose of this batch is to automate the process of making another batch that is used to quiz a person@echo off:startclsEcho Make a Quizecho.echo.rem this part creates a variabl that wil be used in creating the final batch fileecho enter the name of the fileecho .bat wil automaticaly be tacked ont to the endSet /p filename=echo.echo.rem This just creates a ariable that is the title of the the game to be createdecho now enter the title of the quizset/p title=echo.echo.rem this is where the user inputs question part one and it becomes a variableecho enter question part 1Set /p quespt1=echo.echo.rem this ask for the second part of the question echo enter qeustion part 2set /p quespt2=echo.echo.Rem this declares some variables just for shorthandset line=echo.set ec=echoRem this creates a file that user named a while back and then fills it with some preliminary textecho @echo off>%filename%.batecho :start>>%filename%.batecho cls>>%filename%.batecho echo %title%>>%filename%.batecho %line%>>%filename%.batecho %line%>>%filename%.batrem this part is called midstart because ideally later you can repeat this multiple times depending on how long your quiz isset next=0:midstartset /a next=%next%+1rem now we ask for the question of the questionecho now enter the question for the current questionSet /p questmp=echo.echo.rem now we ask for the answer for that questionecho now the answer to that same questionSet /p anstmp=rem More txt inserting (the %%answer%% is used so that in the batch file being created it shows up as %answer%)echo echo %quespt1% %questmp% %quespt2%>>%filename%.batecho set /p answer=>>%filename%.batecho if %%answer%% == %anstmp% goto next%next%>>%filename%.batecho echo you lost>>%filename%.batecho pause>>%filename%.batecho goto start>>%filename%.batecho :next%next%>>%filename%.batecho echo You got it right>>%filename%.batecho %line%>>%filename%.batecho %line%>>%filename%.batecho you have asked %next% question(s)echo.echo.echo If you would like to make a new question simply type "n" and press enterecho However to input your last question type "l" and press enterset /p endchoice=if %endchoice% == l goto endif %endchoice% == n goto restart:restartgoto midstart:endset /a next=%next%+1rem now we ask for the question of the questionecho now enter the question for the current questionSet /p questmp=echo.echo.rem now we ask for the answer for that questionecho now the answer to that same questionSet /p anstmp=rem More txt inserting (the %%answer%% is used so that in the batch file being created it shows up as %answer%)echo echo %quespt1% %questmp% %quespt2%>>%filename%.batecho set /p answer=>>%filename%.batecho if %%answer%% == %anstmp% goto next%next%>>%filename%.batecho echo you lost>>%filename%.batecho pause>>%filename%.batecho goto start>>%filename%.batecho :next%next%>>%filename%.batecho echo you won>>%filename%.batecho echo !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!>>%filename%.batecho %line%>>%filename%.batecho echo click to exit>>%filename%.batecho pause>>%filename%.batEcho And thats it your doneecho.echo click to exitset /p end=And thats it so have fun and feel free to comment

I am trying to make a quizbowl(jepoardy) buzzer system, and I am using an arduino.  I have a program that does a few buttons, and I can add more buttons by just adding more if else, but when I clear it( pin0 and pin3) you have to wait about a second to buzz in, otherwise it doesn't register.  Just a note: the buttons are set up so that I can use 6 pins and control 9 buttons.  It is hard to explain but the pins are setup so that two of the pins sense the current to correspond to the button pressed.  I don't know what else to add, I think it is that is doesn't register that the clear button is no longer pressed, but that might not be it.  Here is the program: const int pin0 = 14; const int pin1 = 15; const int pin2 = 16; const int pin3 = 17; const int pin4 = 18; const int pin5 = 19; const int led1 = 13; const int led2 = 12; const int led3 = 11; int pin0s = 0; int pin1s = 0; int pin2s = 0; int pin3s = 0; int pin4s = 0; int pin5s = 0; void setup() { pinMode(pin0, INPUT); pinMode(pin1, INPUT); pinMode(pin2, INPUT); pinMode(pin3, INPUT); pinMode(pin4, INPUT); pinMode(pin5, INPUT); pinMode(led1, OUTPUT); pinMode(led2, OUTPUT); pinMode(led3, OUTPUT); } void loop () {   pin0s = digitalRead(pin0);   pin1s = digitalRead(pin1);   pin2s = digitalRead(pin2);   pin3s = digitalRead(pin3);   pin4s = digitalRead(pin4);   pin5s = digitalRead(pin5);     if (pin1s == HIGH && pin3s == HIGH)   {     digitalWrite(led1, HIGH);     while(pin0s == LOW || pin3s == LOW)     {       pin0s = digitalRead(pin0);       pin3s = digitalRead(pin3);     }     digitalWrite(led1,LOW);     while(pin0s == HIGH || pin3s == HIGH)     {       pin0s = digitalRead(pin0);       pin1s = digitalRead(pin1);       pin2s = digitalRead(pin2);       pin3s = digitalRead(pin3);       pin4s = digitalRead(pin4);       pin5s = digitalRead(pin5);     }       pin0s = digitalRead(pin0);   pin1s = digitalRead(pin1);   pin2s = digitalRead(pin2);   pin3s = digitalRead(pin3);   pin4s = digitalRead(pin4);   pin5s = digitalRead(pin5);     }  else if(pin3s == HIGH && pin2s == HIGH)  {     digitalWrite(led2, HIGH);     while(pin0s == LOW || pin3s == LOW)     {       pin0s = digitalRead(pin0);       pin3s = digitalRead(pin3);     }     digitalWrite(led2,LOW);     while(pin0s == HIGH || pin3s == HIGH)     {       pin0s = digitalRead(pin0);       pin1s = digitalRead(pin1);       pin2s = digitalRead(pin2);       pin3s = digitalRead(pin3);       pin4s = digitalRead(pin4);       pin5s = digitalRead(pin5);     }       pin0s = digitalRead(pin0);   pin1s = digitalRead(pin1);   pin2s = digitalRead(pin2);   pin3s = digitalRead(pin3);   pin4s = digitalRead(pin4);   pin5s = digitalRead(pin5); } else if (pin0s == HIGH && pin4s == HIGH) {     digitalWrite(led3, HIGH);     while(pin0s == LOW || pin3s == LOW)     {       pin0s = digitalRead(pin0);       pin3s = digitalRead(pin3);     }     digitalWrite(led3,LOW);     while(pin0s == HIGH || pin3s == HIGH)     {       pin0s = digitalRead(pin0);       pin1s = digitalRead(pin1);       pin2s = digitalRead(pin2);       pin3s = digitalRead(pin3);       pin4s = digitalRead(pin4);       pin5s = digitalRead(pin5);     }       pin0s = digitalRead(pin0);   pin1s = digitalRead(pin1);   pin2s = digitalRead(pin2);   pin3s = digitalRead(pin3);   pin4s = digitalRead(pin4);   pin5s = digitalRead(pin5); }} Please help! Thanks in Advance!

At school we were asked to find the possible solutions of making a quiz buzzer and soon we will be asked to make it.

I have a question about a project for school with a arduino uno. I have one arduino uno and 4 servo motors and 2 LCD displays, and some jumpwires (male and female) What i want to create is a race course made out of wood and i want to use the motors as levers. You can play this game with 2 players and the purpose of the whole game is to reach the finish earlier than your apponent. To this game i want to add educational quistions with yes or no as a answer. When a guestion is answered right the levers should open. If you answer a question wrong the levers should stay closed. I also want to make sure that if the player reaches the finish some LED lights blink. Is there a quiz program that i can use or could you help me make my own quiz program ? could you help me. Kind regards, Nassinho.

I want to make an answering system for a quiz game that I am hosting. I want it to be a slap button that will light up the box under neath of the button so that I can see who hit their button first. The system doesn't have to be a lockout system I just want it to be as simple as possible, budget friendly, and easy to make because I am not very electrically inclined. Please help me out and let me know what other information I need to provide. I just want to make two that are not very difficult to build. Button, lights, and power supply connect is all I need.  ALSO, the button is just push connection or momentary connection button. ONly push to turn on the light and NOT push to turn the light back off. Thanks smart people!

Hi guys, could use some creative ideas... i run a pub & we also have a successful themed pub quiz once a week.  it's always a little bit different... in the past we've had teams make an egg throwing machine from bits & pieces such as garden cane, plastic milk cartons etc.,(a surprisingly forceful trebuchet was the eventual winner) & we would like to do something similar. a machine to transport something?  i'm having a massive creative block so some input would be great. ta in advance.

I am trying to make quizbowl buzzers with the arduino.  I have gotten it to work with the nxt, but I want to use the arduino approach, because it is a waste to use the nxt for buzzers when I could be making robots with it... I haven't done much with arduino, in fact I have only looked at a few tutorials and downloaded the software.  But I need to know how to use a "wait until" command so that when a button is pressed a light lights up that on the control box containing the arduino (that corresponds with the button, or buzzer) that was pressed, and the light stays on (waits until) a clear button is pressed.  I'm sorry if the wording is confusing. I don't need a whole program, just the command, how to use it, and maybe a rough skeleton of the program

That'd be actually Really kool, dont you think? BTW, Pop Quiz, is this Windows or Ubuntu? (easy one)

A new study found that after giving the ISI civil literacy quiz to over 2000 people, those who held some form of office scored lower on average than those who didn't!Bear in mind it was close, and both were poor: 44% to 49%, yet it's kind of scary to think about! You can take the quiz yourself, and see how well you do. I got a 64%, which isn't great, but I'm apparently in the top 85% of the random sample!I'm curious how some non-Americans will fare. Please don't be embarrassed to post your score, we won't mock you too much...( via )

For reasons known only to myself, I need to know of some shops popular with British teens. What shops do you guys on that little island like to go to? I kinda need to know actual shop names, I can assume you shop for candy, clothes, gadgets, and whatnot like us on the other side of the pond. Your quiz crazy pal,RocketScientist2015

I know this question comes up a lot in life but someone has been nice enough to help people answer it, only problem is last time I woke up cradled in the arms of a Raptor it survived about 35 seconds before I butchered and fried it... There's a club of such people, Chuck Norris is still working on the T-shirt.Anyway the quiz thinks 1 minute, 41 seconds... Link via Neatorama

Well, I'm not sure if I'm posting this in the appropriate place, so tell me if I am not, but here is my scholarship entry: I would make the physical incarnation of SmarterChild, the infamous AIM robot. It could make casual conversation, remember your name, and do certain tasks on command, such as recall information and entertain a user with dances, jokes, and games. My other idea is a study bot. I would make it so that it could get the information from the subject of choice and quiz you, making buzzing noises when you got the question wrong, and lighting up when you got the question right.

Some of my GCSE students need online feedback on the theme of "storage". Each link is a separate student's survey, and not all surveys are applicable to all demographic groups. I would consider it a favour if members here could respond to whichever surveys they can, preferably within the next few days, and add any (constructive) feedback in the comments here for me to pass on to them. I may be adding further survey links, if more students get the surveys written by the deadline.

PLZ REPLY SOOOOOOOOOOOOON !!! GOOD LUCK BALKEES

.It's alive !Alive, yes, but not as much intelligent than expected ..........Instead of watching a stupid movie at TV, I decided to write a tiny AI programme all in PHP.My goal was to get some functionalities comparable to logic programming languages like Prolog.In simpler words : I wanted to create a programme that could learn facts, and find the solutions to some logical problems.For instance :> blue is colour.Okay.> carrot is vegetable.Okay.> blue is colour ?Yes.> blue is vegetable ?No.> carrot is colour ?No.etc.So far, I can teach it facts in the form of 3-words-affirmations, and I can ask it questions and definitions, and the creature is able to find some connections between facts.Experimentation #1 : > red is colour.Okay> black is colour.Okay> orange is colour.Okay> orange is fruit.Okay(Here, we have a trap : orange is both a color and a fruit.)> red is colour ?Yes> black is fruit ?No> orange is colour ?Yes> orange is fruit ?Yes(Good. The beast did not fall in the trap.)> translate : red- "colour"> translate : orange- "colour"- "fruit"> translate : colour- "red"- "black"- "orange"Good ! The beast can give a sense to the words it learned.Experimentation #2 :> Paul is human.Okay> human eat fruit.Okay> apple is fruit.Okay> human is animal.Okay> animal eat meat.Okay> animal is mortal.OkayNow, let's see if it can "chain" the facts in a logical manner :> translate : Paul- "human"Here it should have replied : "human", "animal" and "mortal", since human are animals, and animals are mortal ...Let's see how it defines "Paul" :> define : Paul- Paul is humanMy creature seems obviously narrow minded ...Let's quiz it now :> Paul is apple ?No> Paul is fruit ?No> Paul is human ?Yes> human is Paul ?Yes> Paul is Paul ?Yes> Paul eat fruit ?Yes> Paul eat apple ?Yes> Paul is animal ?Yes> Paul eat meat ?No> Paul is mortal ?YesAs we can see, it successfully (and surprisingly) replied correctly to each question by connecting facts together, excepted for "Paul eat meat ?".At this question, it should have replied "yes", since it knows that "Paul is human", "human is animal" and "animal eat meat". But it did not ... ... and it's bizarre since it can reply correctly to "Paul is mortal ?", from "Paul is human", "human is animal" and "animal is mortal", or to "Paul eat apple ?" from "Paul is human", " human eat fruit" and "apple is fruit" ...Interesting, isn't it ? =o)If you want, you can submit your facts and questions to my experimental creature (which has no name yet) =o)What would be interesting also, is to confront it to a "paradox" just to see how it behaves ! =o)20080625 : For those of you who would like to have a look at the guts of the beast, here is available the source code.However, keep it mind it's a spaghetti-code and many function names are in french (as well as comments).Also, this version relies on MySQL to store and query facts (I'm planning to replace it with simple arrays though), which make the code slightly more complicated than required ...The main code makes less than 250 lines =o)There is no direct input interface : instead, it use scripts (exp_*.php) that call functions. For example :declarer("red","is","colour"); // <---- declarationsdeclarer("black","is","colour");declarer("orange","is","colour");declarer("orange","is","fruit");verifier("red","is","colour"); // <---- questionsverifier("black","is","fruit");verifier("orange","is","colour");verifier("orange","is","fruit");... which is slightly more complicated than what I showed above for the sake of comprehension and simplification !

(PS: This is me :-) )I might be older than dirt but those memories are the best part of my life.'Senility Prayer'...God grant me...The senility to forget the people I never liked;The good fortune to run into the ones that I do,And the eyesight to tell the difference.''Hey Dad,' one of my kids asked the other day, 'What was your favorite fast food when you were growing up ? ' 'We didn't have fast food when I was growing up,' I informed him. 'All the food was slow.''C'mon, seriously. Where did you eat ?''It was a place called 'at home, I explained. 'Grandma cooked every day and when Grandpa got home from work, we sat down together at the dining room table, and if I didn't like what she put on my plate I was allowed to sit there until I did like it.'By this time, the kid was laughing so hard I was afraid he was going to suffer serious internal damage, so I didn't tell him the part about how I had to have permission to leave the table. But here are some other things I would have told him about my childhood if I figured his system could have handled it:Some parents NEVER owned their own house (my Dad did, it cost him $14,000 for a 3 bedroom rancher), wore Levis , set foot on a golf course, traveled out of the country or had a credit card. In their later years they had something called a revolving charge card. The card was good only at Sears Roebuck. Or maybe it was Sears AND Roebuck. Either way, there is no Roebuck anymore. Maybe he died.My parents never drove me to soccer practice. I had a bicycle that weighed probably 50 pounds, and only had one speed, (slow). We didn't have a television in our house until I was 8. It was, of course, black and white, but they bought a piece of colored plastic to cover the screen. The top third was blue, like the sky, and the bottom third was green, like grass. The middle third was red. It was perfect for programs that had scenes of fire trucks riding across someone's lawn on a sunny day. Some people had a lens taped to the front of the TV to make the picture look larger. I was 14 before I tasted my first pizza, it was called 'pizza pie.' When I bit into it, I burned the roof of my mouth and the cheese slid off, swung down, plastered itself against my chin and burned that, too. It's still the best pizza I ever had.We didn't have a car until I was 9. Before that, the only car in our family was my grandfather's Ford. He called it a 'machine.' It started by pushing a button on the dashboard. I never had a telephone in my room. The only phone in the house was in the living room and it was on a party line. Before you could dial, you had to listen and make sure some people you didn't know weren't already using the line.Pizzas were not delivered to our home. But milk was.All newspapers were delivered by boys and all boys delivered newspapers. I delivered a newspaper, six days a week. It cost 7 cents a paper, of which I got to keep 2 cents. I had to get up at 4 AM every morning.. On Saturday, I had to collect the 42 cents from my customers. My favorite customers were the ones who gave me 50 cents and told me to keep the change. My least favorite customers were the ones who seemed to never be home on collection day.Movie stars kissed with their mouths shut. At least, they did in the movies. Touching someone else's tongue with yours was called French kissing and they didn't do that in movies. I don't know what they did in French movies. French movies were dirty and we weren't allowed to see them.Growing up isn't what it used to be, is it ?MEMORIES from a friend:My Dad is cleaning out my grandmother's house (she died in December) and he brought me an old Royal Crown Cola bottle. In the bottle top was a stopper with a bunch of holes in it. I knew immediately what it was, but my daughter had no idea. She thought they had tried to make it a salt shaker or something. I knew it as the bottle that sat on the end of the ironing board to 'sprinkle' clothes with because we didn't have steam irons. Man, I am old.
