Aluminum cans

Anyone who wanted to could do this experiment. We poured a little water in the bottom of a can and heated it to boiling. Then we quickly put the can upside down in a big tub with cold water. We got a lot of really up crumpled cans and an occasional small "Bang". It was a successful and fun lesson!

Paulina concentrating and preparing.

Caroline really did succeed!
