In an age when we are looking for alternative fuels, there are always some people who go to the extreme, but we are not sure what we are about to report is practical — okay, it most definitely is not. What we have here is a new record for the Mentos Coke MK II car, as it managed to travel a distance of 239 feet.
What makes this record so special is the fact that fewer bottles of Coke and Mentos were used than the previous model. MK I used 108 bottles of Coke and 648 Mentos, whereas MK II used just 54 bottles of Diet Coke and 324 Mentos sweets. This is a long way off hydrogen fuel cells, which is considered to be the cleanest fuel, but it’s certainly fun to take a break from all the serious development in alternative fuels.
The reason why this vehicle was able to travel further with less fuel was due to a number of changes in the design of the car, as well as the so-called rockets also having a few modifications, which you can see if you compare the two videos below of MK I and MK II. One of the major factors was doing what most car manufactures do, and that is to put the car on a diet to shed some weight.
Seeing a car powered by junk food got us thinking about Back to the Future 1 and 2, where right at the end of the first movie we saw that the Time Machine did not need to be powered by nuclear fuel, all he used was Mr. Fusion, which converted household waste into a viable source of energy.
These experiments may be fun, but there is a serious side to them, as one day we could use our own waste to power our vehicles. It’s already happening now, as we have seen on one episode of Top Gear where people are powering their cars on the methane collected from cattle — it’s true.
