Kitchen Chemistry

Room 10 did an experiment so we boiled the water in a Milo tin  then we all moved back and waited for the lid to bounce up I was scared when it popped up when we saw the tin the water was gone we also saw steam.The tin was so hot we had to wait for it to cool and the water was boiling the steam had no way to escape when we put the lid on top.as you see we all got a fright and our experiment worked.
