Mentos + Diet Coke = Fountain!!

The "Mentos fountain" is created by dropping soft mints into bottles of Diet Coke. Steve Spangler turned this really cool trick into an internet sensation on Youtube. There is a website where you can find out how to use this in the classroom. Although the resources are aimed at Y7 & 8 I don't plan to let an amazing trick like this slip by without trying it with my class! Also check out Steve Spangler's website.
