Note to self: Mentos + Soda = Fun!

I'm old enough to never have done this in school, but I hear it's big in science classes these days.

I first read about it in The Star's article "Pepsi and Mentos -- How a high-school teacher's science experiment became an Internet phenomenon and taught kids about nucleation sites along the way."

The first paragraph reads:

Before hitting the big time, the "Mentos effect" was a schoolteacher's gimmick to make 13-year-olds listen up in science class. Drop an unwrapped roll of Mentos into a freshly opened 2L bottle of soda and stand back. The pop becomes a geyser of foam guaranteed to soak the ceiling of anybody foolish enough to try it indoors.

And the obligatory Google search turned up a bazillion sites describing this experiment.

But my favourite one is this from EepyBird.com. Two-hundred liters of Diet Coke combined with over 500 Mentos mints. It's amazing and completely insane.

Cool! The TV show "MythBusters" did something about this just recently. They were trying to figure out the science of why the reaction happened. I found the clip online:
