LAST WEEK A LITTLE BOY DIED IN BRAZIL AFTER EATING MENTOS AND DRINKING COCA-COLA / PEPSI TOGETHER. ONE YEAR BEFORE THE SAME ACCIDENT HAPPENED WITH ANOTHER BOY IN BRAZIL. PLEASE CHECK THE EXPERIMENT THAT HAS BEEN DONE BY MIXING COKA-COLA (OR COKA-COLA LIGHT) WITH MENTOS .
SO BE CAREFUL WITH YOUR SELF EATING MENTOS (POLO'S) AND DRINKING COCA-COLA OR PEPSI TOGETHER.
Scientific Explanation :
Water resists the expansion of bubbles in the soda.When Mentos is dropped into soda, the gelatin and gum arabic of the candy dissolves and breaks the surface tension.This disturbs the water mesh, so that it takes less work to expand and form new bubbles.Also each Mentos candy has thousands of tiny pits all over the surface. These tiny pits function as nucleation sites, perfect places for carbon dioxide bubbles to form. As soon as the Mentos enters the soda, bubbles form all over the surface of the candy. The Mentos quickly sinks to the bottom, releasing carbon dioxide as it comes into contact with carbonated liquid along the way. The sudden increase in pressure pushes all of the liquid up and out of the bottle. When a flavored Mentos with a smooth waxy coating was tested in carbonated water, no reaction occurred,whereas a standard Mentos added to carbonated water formed a small geyser, thus affirming the nucleation site theory.
