Diet Coke and Mentos

Have you heard about this? Apparently if you put Mentos into a 2-liter bottle of Diet Pepsi, it will immediately explode into a messy gusher. So a couple of guys put on lab coats and created a mess set to music that imitates the Bellagio fountains. Impressive stuff, but I would hate to clean up after them.
