Do you know any great physics/chemistry projects?
To a upper-high school academic level. I've been just doing a homopolar motor and supercooling water. Nothing very advanced or interesting. Do you guys know any good projects? Pertaining to Chemistry, I've seen most on Instructables and few on kentchem. Pertaining to Physics, blast away! I've done limited projects although I have few bookmarked for later. Answers that can be made at home are appreciated! Additionally, answers that can be made at quickly with a somewhat limited number of materials are also appreciated.
Well since answering stopped Top answers were from FoolishSage, The Skinnerz, and gruffalo child. FoolishSage wins because of the amount of projects provided. But these were all great answers.
