Diet Coke And Mentos Eruption

When you drop a mentos into the soda tiny bumps on the candy surface give the carbon dioxide molecules a nucleation site or place to stick.

Diet coke and mentos eruption. Kailey uses the smithsonian volcano kit to erupt a volcano using diet coke and mentos after initially experimenting with baking soda and vinegar. It is less clear why diet coke works better than regular coke but based on observation this seems to be the case. Instead it is a physical reaction. Made popular by steve spangler this experiment is a lot of fun and sure to amaze your friends and family assuming you do it outside rather than in the living room.

The eruption is caused by opening a bottle of diet coke typically a two litre bottle and dropping a mentos into the bottle. But the amazing eruption that takes place when mentos are dropped into diet coke or other brands of diet soda pop is not a chemical reaction at all. There s a lot of carbon dioxide dissolves in the soda which gives it its fizz. The reaction causes the diet coke to foam at a rapid rate and spew into the air.

A diet coke and mentos eruption also known as a soda geyser is a reaction between the carbonated beverage diet coke and mentos mints that causes the beverage to spray out of its container. The speed at which the mentos falls through the diet coke can affect how large the eruption is. Because mentos candies are rather dense they sink rapidly through the bottle causing a fast large eruption. One of the most popular experiments of modern times is the diet coke and mentos geyser.

The diet coke and mentos geyser is the result of a physical process rather than a chemical reaction. The more mentos the more nucleation hence a soda eruption. Mint flavored mentos have a pitted surface with lots of surface area which provides plenty of nucleation sites for bubble growth. The candies catalyze the release of gas from the beverage which creates an eruption that pushes most of the liquid up and out of the bottle.
