Electrochemistry (wk.6)
This site is cool. I tried to make the simple heat engine a couple of times. (I'd try again right now, but I don't have any aluminum foil.) The flame burst right thru the foil instead of making it shoot off. Probably an error in my execution- need to fold the aluminum snugly so air can't get it.
The film can cannon Lise made was awesome! I'm going to print up some of these for later use with my son, when he's a little older. (although I'm sure he would love that big *Boom!* now!)
