What materials do you need for a Coke Mentos experiment?
Materials and Equipment
- Mentos® mint flavored candies (24 candies)
- Wax paper.
- Cutting board.
- Knife.
- Index cards (at least 2)
- 2 L bottles of Diet Coke® (6)
- Blue painter’s tape; This can be purchased at most hardware stores or online at Amazon.com.
- Metric tape measure or meter stick.
What ingredients make Diet Coke and Mentos explode?
Primarily, the sugar, aspartame and potassium benzoate included in the candy shell reduce the work it takes to form bubbles in the soda, causing a rapid creation of carbon dioxide bubbles. These ingredients accelerate the foaming action of the soda very quickly, causing the infamous explosion.
What are the materials that come out from the bottle after mixing the Mentos candies and soda drink?
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.
What is the hypothesis for the Diet Coke and Mentos experiment?
Hypothesis: If the amount of soda in the bottle decreases, then the height of the plume and velocity of the liquid will also decrease because there will less liquid with which the Mentos can react.
What chemicals react in Mentos and Coke?
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 are the variables in the Coke and Mentos experiment?
The variable could be something like the number of mentos dropped into the bottle, the flavor of diet soda, the size of the bottle, or the temperature of the soda.
Why is Diet 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.
What is the ratio of vinegar to baking soda for a volcano?
1 tbsp bicarbonate of soda (baking soda) 1 tbsp washing up liquid. 2 tbsp water. ½ cup vinegar.
What are facts about the coke and Mentos experiment?
The diet coke and mentos experiment is also known as a soda geyser. The name is given because when the mentos are dropped in the soda bottle it causes the carbonated beverage to spray out of the bottle. It is one of the most popular experiments of modern times. Make sure to try this experiment outside in a lawn or abandoned field.
What is the reaction between Coke and Mentos?
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 gas released by the candies creates an eruption that pushes most of the liquid up and out of the bottle.
What makes Mentos react with 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.
What is the science behind Mentos and Coke?
The basic science of the Coke and Mentos reaction is fairly straightforward. In fact, it’s not really a reaction at all – or at least it’s a physical reaction rather than a chemical one. Carbonated drinks get their fizz from dissolved carbon dioxide, which is pumped into the bottles at high pressure to make it dissolve.
