I’m sure you’ve seen that famous mentos-rocket science test, all over the tube and perhaps even on your TV, numerous times already. I for one, love it when mythbusters explain why do these mentos propel like crazy when shoot in a bottle filled with carbonated liquid, like coke.
But there’s a new experiment in town, and these people tried to use that mentos-coke concoction to move their self-made ‘mentos rocket car’ through the field. Actually, I thought the results were very astounding. Watch it!
The reason behind this is quite interesting to understand. You should know than on every mentos candy, when it’s inspected over a microscope, its surface is not smooth at all. In fact it has thousands of crater-like holes — and when you put the candy inside a liquid filled with CO2 (like Coke / Pepsi) those craters will aggregate the CO2 in the coke, producing millions of carbon dioxide gases on a jiffy! That explains the rapid propulsion.
The said experiment was done using 108 liters of coke and 648 mentos and the distance it covered from the starting point was 221 feet.
How bout a million?
