What it does?

My submission is using only office supplies, but its not a artsy craftsy submission. The rules say, "It can be fun or functional, big or small- just be creative, and document your project well." Can a business card office supply entry please count!! Not just paper clips and staples are office supplies.

Who Does Well Around Girls?

Who doesn't have trouble around the opisite gender? Who adores the females? Who can simply go up to a girl and have a decent conversation with them without choking or talking giberish? Who finds themselves decent looking for girls to like? Most embarresing situation with a girl? general questions. I personally am ok (and mildly ok) when they ask me a question or need me to help them. I have never started conversations with them but recently a girl that i really have fancied has tried to talk to about tv shows with me out of the blue. :D:D:D:D :P:P:P:P:P I am well chuffed about that. Thankfully i have not yet talked giberish to a girl. yay! I find myself decent looking for girls for me to like and perhaps attractive for them :P. My most embarresing situation with a girl was accidently slammin a door into her face because i did not know she was there. oops lol. Base your posts like that. : P And yes i do know i am curious! Btw susposed to be pic of girls : / heh heh?

When creating an instructable, Publish tab does not work.

Hi, I've been on Instructables for over 3 years and thought I'd create my first instructable today, through the video instructable template.  I have managed to create a draft fine, exactly as I wanted it. But when I click the Publish Tab, the little updating bar comes up for about 1 second, then goes away, and that's it, it's still on the EDIT tab, and has not been published or changed anything. I've tried it in current versions of Firefox and Chrome, but it's the same in both browsers. Everything in the EDIT and SHARE tabs work fine, it is just a problem with the PUBLISH tab. My OS is Windows 7. It is really puzzling to me as to what is happening and any help would be very much appreciated. The Instructable's name is: "How to diagnose & rebuild an electric vehicle winch Part 1 (Warn XD9000)" . Regards, JD

Some instructables force you to login again and then do not acccept your login. Why?

At the top of the page there is a YOU, after a search, you select a topic (e.g fixing antique sewing machines), and you get thrown out of YOU into LOGIN, and then get told you have to go PRO, so you select PRO even though you are already a PRO member, and then the whole stupid process starts again.

My instructable doesn't appear in the list, I added it yesterday

Hello, Yesterday I published an instructable, and I found it weird that there are still 0 views. So I searched for my instructable in the correct page, and sorted them by Recent and it doesn't seem to be there. This is not the first instructable I publish here, the others are working perfectly, and they do appear in the 'recent' list. What could be wrong? I also tried unpublishing ad re-publishing the instructable but that also didn't help. (link: click) Thanks in advance, Electorials

Front Page Feature Never Showed Up

I got an email stating that my latest instructable was featured on the front page, but I never saw it there. Did anyone else? I got the email around 5:30 am, does that mean it was featured for a bit in the early morning and then disappeared into the tech category? Is there a significant delay between the time something is chosen to be featured and the time it appears on the front page? Thanks! Xellers

It may just be my google-fu failing me, but I can't find switch I am sure must exist: A sliding switch with reversing (DC) polarity. At one end of the slider, power is full "forward".  Slide the controller, and power decreases.  Reach the centre, and power is zero/off.  Slide past the centre, and power increases again, but with reversed polarity, ie in reverse.

does this works in practical?

Car running without fuel first i will take some water in petrol tank of a car.now i will connect it to a electrolysis box. the electrolysis gets electricity from battery. now 2H2O[water] on electrolysis divides into 2H2 + O2 this in the engine with the help of glow plug combines and gives 2100C -2800C temperature  and water [in gaseous state] with that temp[ car works as in normal case].The water in the exhaust cools down and again goes back to the water tank. By this the cycle continues and car keeps on working. it will be like this, Battery                       Electrolysis box  [water to it comes from water tank ]              2H2,O2                 2H2+02 [in engine]                                                                                                                       2H2O + 2100-2800 Celsius temperature [engine works] water tank please tell me does it really works out or not

does this work out?

Production of light with low energy  for this take a long tube with both ends open.Now place a one way mirror in such a way that light passes from outside to inside and the other end with a colored glass except red [primary colors].before this just fill it with active medium or the elements used in laser[make sure that this medium emits any color other than red on exited] Then send red laser light into the tube for few seconds if my guess is right the tube will give a colored light outside Now let me explain it when the red laser light first enters the tube it makes the active medium in it excite and release a colored light along with the red light this passes all through the tube and at the end the colored glass [the same color which the medium emits on exciting] will send the emited light through it and reflects the red colored light back and the process keeps on going as the first one way mirror even reflects the red light back. I have a picture of laser active medium and one way mirrors.           So,energy is consumed only for the first production of light for minute.

Does anybody else have summer homework?

Is it not the most ridiculous thing?! I have to read 2 (count 'em - two) books and do a book report on each, one of which includes making maps, graphs, and a load of other stuff.To me, summer is supposed to be a break. Like, Christmas break, or Thanksgiving break, where there shouldn't be any homework given.And what's even more stupid (but slightly funny in a way) is that I'm going into 9th grade. All the teachers and counselors were saying how much stress you're going through, and then they make us do all this homework, which is major grade, be due on the first day of school?I'm not in AP classes either. Just 9th grade gifted! It's crazy!Geez! Shouldn't there be a law against this?
