Alright, so this is a strange post, but I thought it was kind of cool. I was at a party yesterday to send a friend off to Prague for the year and somebody wanted to have a homemade fireworks display, of sorts. He had heard on NPR that if you drop Mentos into coke, it makes the coke virtually combust, sending it exploding out of the top. This happened almost immediately when the mentos hit the coke.
I guess the moral of the story is, don't chug a coke and then eat a mento. :)
