Well, we finally did the Mentos and Diet Coke experiment. It's something I've been wanting them to try for a long time. Maybe I should have waited bit longer. Meh. They had fun.
Some of my notes on this experiment:
-Don't let the youngest child handle pouring in the Mentos, no matter how much she begs. Better yet...
-Invest in the little tube with the pin that you can attach to a long string. That way they can stand further back.
-Seltzer definitely doesn't work. We're not sure why yet. It might be something about the flavoring and sugar in the water making it fizz slower.
So here's the video. Enjoy.
