One upping Dave: A Diet Coke and Mentos Rocket!

[Barry Bonzack]

I finally got around to loading Gabe and I's launch. We decided about a month ago to use our waterrocket launchpad to do a Mentos and Diet Coke rocket launch. No throwing the bottle on the ground, no chance of it coming back and harming people or property. It Did launch over some powerlines, though. This was after work out at the Astronaut Hall of Fame. The following videos are taken with the Google camera from the KOP, step by step.

Gladwrapping Mentos

The Launchpad

Loading Mentos and putting it on the pad

Pumping air into rocket to seperate the mentos from the gladwrap and add pressure.

LAUNCH

Recovery


And just for the fun of it, we decided to drop some diet coke and mentos from the roof of the Astronaut Hall of Fame. Mentos Deathdrop

Enjoy!

Advice for the next group that tries this: use a tripod.

Where can one buy that "pad"?

Is it just me or does the guy shaking the bottle on the roof remind you of one of the Sand People from Star Wars...
Anyway, it looks like the Deathdrop did something similar to the rockets my brother and I made. One sort of flew sideways a bit and the other blew the bottom of the bottle out. (Does anyone know if the 50¢ Walmart coke doesn't work as well as real Coke, because that's what we used)

From much experience, we've deducted that the 58¢ Diet Sam's Choice Cola from Wal-Mart works just as well as regular Diet Coke.
