The marvels of modern science...

...OR, why do Mentos & Diet Coke do that??

In fifth grade, all the kids get to make volcanoes & set them off at school.

Madison brought home a paper explaining the materials she could use to make the volcano & also the different ways to make it erupt. I was quite surprised when I read "mentos & diet coke" next to the old stand-by "vinegar & baking soda".

Of course, given the choice between a large shooting geyser of diet coke, or a pathetic, dribbling ooze of vinegar, who wouldn't choose the former? Madison said no one in her class opted for the vinegar approach. DUH!

Unfortunately, I was out of town the weekend that the volcano was to be constructed, so Cory & Madison had to fend for themselves. They did a pretty good job, eh?

Cory spray painted the salt-dough volcano & Madison added some orange lava streaks for dramatic effect.

Then, it was time to set them off. Unfortunately, Madison was a better picture-taker than her friend, so she got a great picture of someone else's volcano erupting...


...but this is all we got of Madison's volcano erupting.

Oh well, she still had a great time. But, they still didn't explain why DO mentos & diet coke do that? Guess I will have to look it up...
