Mythbusting, Tuesday, Period 2
Tyler smiled slightly at his class as they assembled. No lab supplies were in evidence, just a TV at the front of the room. "Morning. We're just watching a video here and then we're going outside for the experiment -- the Diet Coke-Mentos eruption."
He cued up a DVD player at the front of class. "This is an episode of Mythbusters --- yes, the show I named the clas for -- showing the science behind what we're going to do. I would have a lecture, but I wouldn't say anything the magic box won't already tell you. These guys are good."
The episode played, explaining that the reaction, in which Mentos dropped into a bottle of Diet Coke produce a fountain as tall as a person, is a product of the caffeine, potassium benzoate, aspartame, and carbon dioxide in the Diet Coke and the gelatin and gum arabic in the Mentos, as well as the rough surface of the candies.
When it was over, Tyler turned off the TV. "And now, you get to do this yourself. Grab a buddy and we're going outside. I have Mentos, Certs, M&Ms, Skittles, Diet Coke, regular Coke, and plain soda water, plus Diet Pepsi, so you can play around and see what makes the best fountain."

Alex waited until he counted down to one and started running. She was expecting that thing to go pretty high and glanced back to check on it, as she ran. Though, the whole watching it as she ran thing might not end well.

Alex was expecting it to go fairly high -- she'd seen ones that reached eight feet -- but she was disappointed that it didn't reach that height. "I wonder if the certs would react better."

She walked back to the candy and grabbed a cert. "Ready?" Alex held it over the bottle, waiting to drop. "Same thing as last time?" With the whole counting, dropping and running thing.

"Okay, here goes nothing." Just like before, she counted down with her hand and then dropped the cert in the bottle. And ran for it.
