How nucleation of Mentos increases with warmer soda?

The temperature of the soda also factors into geyser size. Gases are less soluble in liquids with a higher temperature, so the warmer your soda is, the bigger your Mentos-induced geyser will be. This is because the gases want to escape the liquid, so when you drop the Mentos in, the reaction happens faster.

What type of energy is Coke and Mentos?

There is potential energy stored with the Mentos and when added to Coke Light, you end up with kinetic energy (fountain spraying) and sound energy (fizzing of carbon dioxide).

What chemicals make Mentos and Coke react?

Experiments in a 2006 edition of the Discovery Channel programme Mythbusters suggested the chemicals responsible for the reaction are gum arabic and gelatine in the sweets, and caffeine, potassium benzoate and aspartame in the Coke.

What kind of experiment is Coke and Mentos?

Transform an ordinary day into an extraordinary one by combining Diet Coke and Mentos to create a spectacular soda fountain. Kids love watching (and doing) this fun, easy chemical reaction that combines two delicious ingredients to create a geyser of carbon dioxide bubbles.

What makes Coke and Mentos explode?

As the Mentos candy sinks in the bottle, the candy causes the production of more and more carbon dioxide bubbles, and the rising bubbles react with carbon dioxide that is still dissolved in the soda to cause more carbon dioxide to be freed and create even more bubbles, resulting in the eruption.

Why is Coke and Mentos a physical reaction?

Since the addition of Mentos is just speeding up a physical process (i.e. the carbon dioxide gas coming out of solution), the reaction is a physical reaction. This is a state change for the carbon dioxide gas from being dissolved in Coke to a gaseous state.

Why is Mentos and Coke a physical reaction?

How do you do nucleation?

Mechanical methods: Shaking, tapping or applying ultrasound can be effective for nucleation, but difficult to standardize. Shock cooling/controlled rate freezing: Exposing the sample to a rapid set of temperature ramps can promote nucleation.
