The Awsome Times!
One thing that I did in 5th Grade was Exploding Effervescence. Exploding Effervescence was where you use Diet Coke and Mentos and drop the mentos into the Diet Coke and it explodes. We used about 100 Diet Coke bottles and about 600 mentos. It was very fun to do that and if I had a chance to do it again I would. After we were done we were all sticky and soaked with Diet Coke.
