Mentos and Soda Experiment
Ready to try the most memorable summer science experiment? This mentos and soda experiment may not be summer themed, but because of the BIG chemical reaction, you will want to do this mentos and pop activity outside. Doing the mentos and coke science project outside allows for virtually no clean-up which makes Mom happy too! This summer science is so fun your kids will not even realize they are learning! Try this fun summer activity with preschoolers, kindergartners, grade 1, grade 2, and grade 3 students.
Mentos in Coke
All you need to try this simple science project are a few simple materials you may already have on hand!
- 2 liter bottle of soda
- 12 mentos mints
- index cards or construction paper
- mesuring cup
- rain poncho or umbrella (optional)
Use your paper to make a tub that fits your 12 mentos and tape it into place.
Make sure the mints fit easily, but stack neatly for a quick release.
Make a slit for a piece of paper you can quickly remove to drop the mentos in the soda bottle
Unwrap the white mentos candy and load mentos inside your dispensor .
Coke and Mentos Experiment
This part is optional, but makes it extra fun expecially for young learners! Make your soda bottle look like a rocket. Find somewhere outside where you can launch your rocket where you have some space to not make a mess. We like to do this on the grass before it rains as the rain will clean it all up for us!
mentos diet coke
You have to do this step QUICKLY or you may get soda on you. Carefully open the bottle of soda and place the index card on top of the opening and your tube of mints of top of the card.
You can wear a poncho if you like or have them do it in their bathing suits with sprinkler ready for your next activity to get the kids clean. LOL.
Mentos and Coke Science
Quickly slide out the index card so the mints drop in the soda bottle.
Time to move quickly or you will be covered in soda. WOW!
How cool is that? It gets really high, doesn’t it!
Mentos and Pop
After your kids fisnish giggling and exclaimed with delight, pour the bottle of soda that’s left in a measuring cup. How much was left? Now try it with different sodas if you like such as diet coke, Vernors, Cherry Coke, etc. Which one cause the biggest explosion and left the least amount of soda left in the bottle?
Diet Coke and Mentos Experiment Results
Wondering what happens in this classic science experient? Basically, the coke and mentos explained is that soda gets it’s bubbles or fizz from carbon dioxide gas that is dissolved in the soda. When you open a bottle of pop you hear the fizz and see the bubbles, right? This is especially noticeable with a new bottle of soda. If you shake up the bottle there is even more fizz and bubbles because the gas is released faster. When you add mints, the bubbles come out of the soda EVEN FASTER; so fast that it takes most of the soda out with it. This makes a truly EPIC expplosion that will delight kids and adults of all ages.
Observe the mint carefully. Can you see the tiny holes that feel chalky. The ingredients and unique texture help break up the hold soda has on the carbon dioxide. If you want to try it with another flavor you’ll notice they are smooth. The waxy coating on other flavors keep them from dissolving and freeing the carbon dioxide gas in the same amazing erruption!
