So, this is definitely not practical or even a conceivable alternative if scaled, but it is definitely cool. EepyBird, the guys that brought us the original Diet Coke and Mentos videos are at it again, this time with a vehicle powered by the pair. Just 108 2-liters and a whole bunch of Mentos later, and they’ve done it.
The vehicle directs the explosion toward a solid wooden wall allowing the vessel to propel itself forward using nothing but Mentos, Diet Coke, and a little ingenuity. We’ve embedded the video below. Enjoy!
