Picture of EXTREMELY Simple
           Today i was starting to make fan blades and accidentally found out how to make this amazing... fan... air conditioning... thing!!! It actually works very well; better than i thought it would. It literally took 1 minute to make, and thats only because I didn't think I was going to make this, so I was being very careful when drawing the lines. ( I don't know if the way I word my sentences is correct. I apologize if they aren't; I'm just very exited to post this instructable!!!) 

Well, i don't want to keep you guys reading forever, so I will go on with the show.

Did not cool anything at all, not even the hand i was pumping with. Cool idea and easy design but i haveto say that it is totally useless....

Or you could just squeeze it...

so the cool air comes from pumping up and down? if you stop pumping (I mean, what if you're going to bed) there'll be no cool air any more?

977 btus/lb of ice.
Average a/c 24,000 btus/hr.
heat generated by pumping action means this device will probably make you hotter.

i don't know about that. if it does, its unnoticeable. the immediate effect of the cooled air actually feels pretty cool. now, i may be wrong though.

would it work to stick a fan unside of it?
ducktape.mac (author)  mcaliber.504 years ago
yeah, it should. like if you put a small desk fan, or found out how to wire a computer fan over it. thats a really good idea!
The light of discovery is a wonderful thing.

What do you do when you're done?
ducktape.mac (author)  Dr. Pepper4 years ago
you kinda pump it. like grab the part where you screw the top on, and slide it up and down.
And then? Could you provide a video?
ducktape.mac (author)  Dr. Pepper4 years ago
thats all there is to it. i added some pictures on the last step. if that doesn't help, then i will try to fix my video camera and do a video.
