Here is a link to a listing of really Cool Gadgets and such... And what is up with this ? Newtonian Fluid ? I think I want one of these chairs :-) As well as the Sun visor @ mp3/.TV/.DvD listed there. Items like the Rubik's Cube for the blind are cool too. There is even an RC camera car and matching virtual headset combo :-)

Hey all, I wasn't able to find where a short discussion about Super cooled water was posted not long ago, and I wanted to relate this incident; so if I get no replies, that is ok. I just thought it was kind of neat the way this occurred. Last night, well, I guess it was actually this morning ( 00:30 ), I left work and went to my car, got myself situated, and before driving off, I grabbed a bottle of water that was in the cup holder. I distinctly remember shaking it to make sure the water was NOT frozen. I also took note that the bottle was partially imploded; something I would have expected as the temp was down to about 17 o F. When I opened the bottle, put it to my mouth and tilted it, the unexpected happened. Between the moment of releasing the vacuum that had formed and my trying to drink from the bottle ( about 3 seconds), the water froze to a Slushy consistency. For a moment I was perplexed why I was getting no water in my mouth, and then it slid from the bottom, and it stopped at the neck of the bottle. I had forgotten that this could happen. I must have sat there looking at it for a good 2 minutes trying to get something out of the bottle, when I thought I would blow some warm air into it. The bottle inflated slightly, and the air passed by the slush, and when I released, I got a face full of slush. I had to laugh at myself all the way after that little incident. :-)

Ok I had an idea... Yesterday while I was taking processors off of motherboards.... I found a rather normal looking heat sink. and droped it on my hat. By now you have probably figured it out that I have a messy room and I want to make a cool(ing) hat. So I am thinking of running a little pump (very little) and fan off of 1-2 9v batteries. Some Kind of coolant (water) and a couple of prototypes And I will have a cooling hat.... (YES PEOPLE I REALIZE ITS WINTER!!! (where I live)) Any ideas ?

My dad recently pulled a switch out from somewhere, and it looked cool, so I kept it. As far as I can tell it still works, and I believe it is Double pole double throw or something like that. I don't have any idea what to do with it though. D: Any ideas?

When I saw the sandblaster here, I wanted to make one because well, it's cool. The only problem is that I can't find the gun. From what I can tell, It has 2 intakes and one exit nozzle. I did read the instructable, but it didn't say (as far as I could tell). Can someone help?

Hi, all! I foster dogs and cats in Baton Rouge for several non-profit agencies. Lately, I've had more than a few feral cats needing a temporary home. I had an idea (inspired by something I saw online) to use the trunk from the crepe myrtle tree my boyfriend chopped down to "catify" the carport where they like to seek shelter at night. Considering that I've never owned a power tool until now, I think it's coming together nicely so far (pics attached). Please keep in mind that I'm no carpenter.... This is south Louisiana where the Summer temps are high and the humidity is even higher. I can only imagine how awful that must be when you are sporting a full fur coat outside! Here's where I need your help: I want to make cool gel mats to fit the odd shaped green shelves you see attached to the walls. I have been sewing for many decades, so making these "cool" cushions to fit is not a problem. The problem is how to make the GEL that goes inside the mats that keeps the pet cool. I'd rather not use any toxic chemicals, just in case one of them punctures the gel mat causing it to leak and then decides to drink the gel. So, maybe there's a chemist out there, or just some intelligent individuals that might have the answer to my problem? Any and all suggestions are very much appreciated! Thank you, Linda

I currently don a teenie-tiny plastic brown-bag shaped lunch tote that barely fits an 8oz water bottle, sandwich, chips, and ice pack. I need something with a bit more room for food. At an impressive 5'3" and 105 lbs, I'm a growing man, and I need my fuel. But I don't want just some clearance-rack generic latest-movie/pop icon plastered lunchbox, no sir. I want an bullet-proof, high-capacity, industrial-strength lunch transportation system. Something that will make people say "Holy crap, that guy's a MAKER." I want a lunch box that scores major cool points. Something that has character. Something that has features, like extreme insulation or something. Bottom line: it needs to be big, look cool, and last a long time. Price isn't an issue, Christmas is coming up :D So, ibles, how cool is YOUR lunchbox?

My computer has these vents on the case that are blowing out cold air while my expansion slot vent is blowing out VERY hot air. I was thinking I could cover up the vents that are blowing out the cold air which is very cold so I could make the inside of my comp cold so my video card doesn't get as hot. Is this a good idea?

Is it just me, or is the science section as a whole getting suckier?Science is my best subject. I get A's in school, avidly read Scientific American and other science magazines, read physics and astronomy books, and once gave a 45 minute speech about the viability of Algae as bio fuel (Instructable coming soon) for a science project. So obviously, when I first joined, I ate up the science section, reading through great instructables, like the ones created by egbertfitzwilly (oh, shut up, you know who I mean) and other great instructablers. I loved them. Now however, it seems to be full of toy guns, electronics projects that belong in tech and recipes. Goda**it, just because your beer recipe uses yeast doesn't make it a freaking science fair project! If your instructable doesn't need a second category, DON'T GIVE IT A SECOND CATEGORY. Whoa, that was hard, eh? For instance, this. Its not a bad Instructable, sure, what what the heck is it doing in the science section? How about the ginger beer instructable? Or smart LED's? Or a coding machine? I want, and I'm sure others want, more Egbert and Nurdrage styled instructables, with cool stuff that makes us go "Whoa" and want to do it ourselves, not some of the random junk that people seem to throw in to get an extra 3 hits.

Hey Guys,I've been exploring this site for a few months now but didn't make any post yet. I thought of making my first post here and to say hello to you all.Here's me at a glance, skip this if you want :). One part of me lives in Dhaka, Bangladesh, a graduate in Computer Science (2004) and works in Software Company, but the other (and perhaps the real) part of me is a just obsessed about C++, Digital Electronics, Machine Intelligence and of course, Robotics.I maintain the following blogs:My General BlogMy Robotics BlogI would like to introduce my latest robot, named 'Dobo' which is a robot dog. It looks nothing like a dog yet.. but soon it'll. Here goes some videos: Let me know how it looks. I have plans to improve it more soon and I've bought a cute skin for it. Look forward to have great time with you all!Regards,-Kaisar

It is very possible and it is in use today by using Thermal Cooling and Heating from the earth. Performed by using a 6" well at least 100' deep, with thermal tubing inserted into the well carrying the liquid to be cooled/heated. Process is done by a circulating pump in the interior unit - through the coil - sending back through the well system and returning. It starts out from the main unit circ pump.......through the coils.......out to the "down tube" into the 6" well pipe, a sharp 180* turn back up the system returning to the circ pump. Such a system is used by many facilities to Air Condition or heat rooms of about 15' x 15' or so. I have even seen a system that utilized creek water as the "cooler" of the tubing on a circ pump system. That one really was cool, about 52 degrees. Have you heard of these systems or seen something like it or close?

Do you own weird or exotic pets or do you know anyone with weird or exotic pets? I knew a guy who lived not too far away from me with four Siberian tigers, pretty cool but he ended up having to send them to cat tales, but anyway... Why am I asking, I just wonder if other people have cool pets like that. The tiger in the pictures name is Delilah, she was 8 when the picture was taken.

How cool are Ninja?A lot of people think just the word is cool, that Ninja are the ultimate (everything).A lot of people spend much time bickering over who are "real Ninja" or not.People also find Ninja films amusing (or even hilarious, myself included)And of course the "Official Ninja Website"Beyond people who think Ninja are totally awesome, I'd like to know what they've really done?WW2 - any involvement in the Pacific?Assassinations - anyone famous?Kicked-organised-crime-ass?Overthrown any governments?Killed anyone?Are the real Ninja subject to some conspiracy-outlook where "if you've heard about them they aren't real Ninja"?Anyone?
