This is a fun website to go to if you want to see what you can do with all of those marshmallow peeps! http://www.peepresearch.org/
Interesting, but somebody must be bored for sure. Believe it or not, I sit here and have 12 Peep bunnies that my kid got for Easter taunting me. One is actually winking at me, like "go ahead; take one." I know its just marshmellow and sugar but they have been a tradition since my childhood. I could eat half the pack right now. Give me strength.
It was two scientists at Emory Univ. who "conducted" all the experiments. They were featured on CNN a long while back, claiming they did it while on a sugar high from eating...PEEPS! I used to show parts of this to my science classes and we talked about the scientific methods. It was a lot of fun.
