Mentos Mini-Rocket Car

Download complete instructions at http://www.eepybird.com/

How far will Mentos mints propel a single bottle of soda? The big rocket car, powered by 648 Mentos and 108 bottles of soda, carried Fritz 221 feet and carried David Letterman 364 feet (but to be fair, he was going downhill a bit). Using a single 2 liter bottle of diet soda and 6 Mentos, the mini-rocket car has (so far) gone 176 feet!

If you're a kid, don't try this without a responsible adult supervising. If you're an irresponsible adult, don't try this.

Make sure you wear your goggles, use the wrist strap (to keep the piston from flying away accidentally), and aim away from people, cars, buildings, and other objects.

Be safe, have fun, and explore your world!

you guys are the coolest. what is the song? it is pretty beast!

[EepyBird]

@101fatherboard The song is Soul Sequence by AudioBody from the album Do Something Difficult. Glad you like it!

This is fantastic. I can't help but wonder if it would be more effective to have a shorter piece of PVC. The tube you have drags on the ground and creates a lot of drag. On the other hand, if you made it too short, I imagine it would cause the car to spin around instead of going forwards - I'm sure the PVC hanging off the back is acting as a stabilizer. Might be worth some experimentation with differing lengths of PVC - but then, I imagine the EepyBirds have already done these tests.

@Cheesius Yep, you're spot on! We tried shorter and the rocket car did indeed spin out of control. We did find a tube available from a specialty plastics manufacturer that is lighter than PVC and that was a bit better. But we set ourselves the goal of making this rocket car with only what you can find from your local hardware store, so PVC won on that front.

it would be interesting to see tony hawk with mentos skateboard

[Legostunt542]

make a ramp for the car

[AWESOMEGUNNER300]

u guys rock the house : ) : ) :) :) :) :) :) :)

[ItsMeJnK]

i tried this but it only went 19 ft i did every thing you said but it looked like the tube made it stop so i thought about adding a wheel to the tube would that work?

Make a coke and mentos airplane (attach wings and add a ramp)

kereeeennnnnnnnnnn

[inhumanundead]

I'm now blueprinting a mentos and coke vertical rocket. Scheiße ja!

[elhijodechucknorris2]

NICE !!

[roukurai]

can you subtitute de mentos for something else?

would it be the same thing with vinegar & baking soda?

[colistro]

now we should try doing a mentos + coke powered vehicle.
