The Mentos/Coke Experiment

My kids had been bugging their dad to do an experiment with Coke and Mentos.  I don't know if you've ever heard of combining the two, but the effect is, well, let's just say, explosive.

Today my husband came home from the grocery store with a couple of two liter bottles of Coke and a roll of Mentos.

"Mommy, we're going to make an explosion!" my daughter said.

"Terrific," I said.  "Where?"

"In the backyard."

Well, at least it wasn't going to be in the house.

I went outside to see the big event.

My husband took the cap off of one bottle of Coke.  My daughter put in two Mentos. 

Everyone took a few steps back as the Coke exploded out of the bottle.  This thing looked like a geyser.

My kids squealed with delight.  "That was cool!  Can we do it again?"

My husband obliged.

This time they put six Mentos in.

Let me just say, there was very little Coke in the bottle after that one.

"Okay, kids.  Who's cleaning this up?"

"Bring out the dog!" they said.
