How do you make a Mentos geyser?

How do you make a Mentos geyser?

Step 1: Remove the lid from the Diet Coke and set it the bottle of soda on a flat surface.

  1. Step 2: Roll the paper into a tube around a pack of Mentos mints, tape it into place and pull it off of the roll of mints.
  2. Step 3: Hold your finger over one end of the paper tube and have your child fill it up with Mentos mints.

What causes the geyser when Mentos are added to soda?

Mentos candies contain millions of cavities, roughly 1-3 μm in size, that remain unwetted when added to a soda. Because of this, the addition of Mentos candies to a carbonated beverage provides enormous numbers of pre-existing bubbles into which dissolved carbon dioxide can escape.

Does the temperature of the soda affect the Mentos geyser?

My conclusion is that the temperature of the soda does have a major affect on the height of a Mentos geyser, with heat creating more energy to produce a higher geyser. This project shows how heat intensifies a reaction when Mentos candies are dropped into Diet Coke.

Why does Mentos make a geyser when you drop it into Diet Coke?

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.

Does the amount of Mentos affect the height of the explosion?

Analysis: This graph does a good job revealing the relationship between the number of Mentos put in a Coke and the height which the geyser will reach. At first when a Mento is added, it affects the results dramatically. As the number of Mentos grew, the impact of each additional Mento decreased.

What evidence did the team find that the reaction between the Mentos and soda was a physical change?

Mixing Coke and Mentos looks like a chemical change, but since the gas released is carbon dioxide AND it was present before the foaming happened, it is actually a physical change.

What soda has the best reaction to Mentos?

Diet Coke
Diet Coke and Coke Zero react better with Mentos than regular Coke does because of the absence of sugar. A lack of sugar makes the soda mixture less viscous, given the presence of sweeteners, like aspartame, lowering the surface tension even more than usual.

How many Mentos are in a 2 liter Coke?

Yes. Five mentos strung on a wire: and dropped into a 2-liter diet cola produced the following geyser: Five loose mentos typically produces a geyser that’s 9-feet tall.

How does the temperature of the soda affect the height of the soda stream when Mentos are added to soda?

Hypothesis: The larger the number of mentos, and the warmer the temperature of the soda, the higher the reaction will be. This is because the warm air would have a greater volume and would exert more pressure, which would force the soda to a higher height.

Does the Mentos trick work with any soda?

The trick works with any carbonated beverage. It works with regular cola, orange soda, root beer, etc. It’s actually very cool when performed with tonic water under a black light because you get a glowing blue fountain. However, you can use seltzer water (very easy cleanup) or any soda.
