I tried that. Well, actually, I made an electromagnet with batteries to see which one would have the biggest force.

Little did I know that AAA, AA, C, D are all 1.5 volts.

Maybe the size does have an effect. I don't know; I forgot my results. xD

Hmmm ... Physical Science? Medicines would be part of chem, right?

Last year, I did "which analgesic dissolves the fastest" by putting different analgesic (Pain killers such as Tylenol, Aspirin, Aleve, etc) in a hydrochloric acid/water solution.

But again, I think that's chemistry/biology.

but we use tums and i forgot the other--- it's for stomach pains

then examine the chemical content, why is it faster and such
