Build Your Own Band-aid Fuel Cell
ptorrone writes "Here's how to make a fuel cell from a band-aid...This has got to be the simplest way to build a fuel cell from scratch. The design is ridiculously simple, whilst being effective - it will allow you to explore the concepts of fuel cells in a ludicrously simple way."
First get a band-aid. Make sure it has a large sterile pad area.
Remove the backing from the adhesive and set it aside. Next, buy a fuel cell from the online fuel cell store. Then, carefully attach the fuel cell to the adhesive part of the band-aid.
Finally, wave your wand while saying "A-la peanut butter sandwiches", and hey presto! it is done!
Hah! That's what I was thinking when I read that. Build your own nuclear reactor using a band-aid. Strap band-aid to functioning nuclear reactor procured from post-Cold War Russia. Voila, Band-Aid Nuclear Fission Reaction System.
