Mentos and Diet Coke Soda Explosion, Free Video Clips
When Mentos meet Diet Coke soda, watch out. The bottle explodes and you're going to get wet. Is this experiment rocket science or is it art or is it comedy? When five or more Mentos candies are dropped into a bottle of Diet Coke, an eruption results and the soda geyser takes off. Carbon dioxide bubbles form in the porous surface of the Mentos, the pressure increases inside the bottle and whoosh! This phenomena has become the stuff of performance art shows.
Hard to believe, but science is not sure what cause the Mentos-Diet Coke reaction. It depends on the porous structure of Mentos, and doesn't work when fruit flavored Mentos are used, because they have a waxy coating. Mentos in plain carbonated water create just a small geyser.
According to the Discovery Channel, the caffeine, potassium benzoate, aspartame, and CO2 gas contained in the Diet Coke and the gelatin and gum arabic ingredients of the Mentos all contribute to the geyser effect.
The biggest soda geyser recorded is 34 feet. One way to improve the height of a Mentos reaction with Diet Coke is by freezing the Mentos. The gum arabic they contain expands when it freezes like water and make the Mentos even more porous for a bigger, faster reaction. It also helps to put a nozzle on the bottle for more pressure.
I wish you much success in life.
I hope you have a very happy day.
