One upping Dave: A Diet Coke and Mentos Rocket!

[jdglove]

Correction to my earlier post (controlled Diet Coke Mentos Rocket Launch)..

It seems that using 4 mentos instead of 5 is too few and the rocket will
not have enough thrust to push out the cork sometimes. So add a fifth,
but to get all five flush with the cork and above the soda you have to
squash them by about a third. This does not harm the reaction but you then have time to cork and overturn the bottle!

BREAKING NEWS!!!!

On Wednesday, August 9th Jaime of Mythbusters throws his beret into the DC&M ring!
That's right, the Mythbusters will be doing Coke and Mentos rocket experiments!

Hopefully this will not only give DC&M national recognition, but also answer the question once and for all "what exactly makes this work?"

I am also hopeful that the Mythbusters will be able to develop a simple yet reliable launch system.

As long as there are no legal issues, someone needs to record this episode, put it on Youtube, and then post a link.


Excuse me for geeking out, but this will be a great moment in Diet Coke and Mentos history!

It is possible. According to his profile, his latest activity was on Tuesday.

Yes, it is.

He's been on here for quite some time but keeps a low profile, for obvious reasons.
Not only is he involved with competing with his Battle bot but he's been a mentor on FIRST team 841 for several years now.

It's that science and technology inspiration stuff - never know where it'll take you -

Anyone see this? $750 in prizes a month for a simple experiment! I think the best one i saw (a little dangerous) was diet coke + mentos + dry ice ! It was pretty cool. It blew up cause of pressure but you could see the bottle get to like twice its original size before it blew! I bet with a hole in the cap it would make a HUGE fountain!

I plan on doing this this weekend. I bought a special drill bit (1/16") for the cap and the mentos. Heh... maybe I'll have some pics to post.

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!

looks pretty darn cool barry. we just talked about it at work, didn't really do it lol.

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

Where can one buy that "pad"?

[lukevanoort]

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.

I'm sorry , but, WHAT?!

I've never seen this done before and how do you get the mentos into the soda? do you just dump them in?

someone explain this whole process

what do you do?!

umm...where do I go?
