So if you didn't see our other blog entry on the diet coke + mentos here is another video of it. The original video was pretty blury and this one is of a different person and much clearly. Anyway the premise is you take a tube of mentos, dump them all at once into a liter of diet coke, and clear the way for fireworks. The citris acid or some such on the mentos reacts with the carbonation in the diet coke to produce a giant geiser of soda. In this video they also try the mentos in some carbonated water but it doesn't have the same effect. Were the mentos already used or does carbonated water just not cut it. Make sure you turn the sound off on this one because it has Steve Ballmer screaming "Developers Developers" throughout the entire video.
