Diet Coke and Mentos "Failure"

This year, for Van Dyke's Sports Camp VBS, we're doing a more general "Science Olympiad" instead of just Robotics. Tonight we played with Diet Coke and Mentos. I built a half-dozen nozzle rigs like this. The one in this video has a diagonal slot cut into it.

It was cool enough that we spent the rest of the time trying to get another bottle to take off horizontally, without much success.
