The crushed Mentos candy should sink slower than a whole Mentos candy. In this materials science project, you will see if using crushed Mentos candies instead of whole Mentos candies, which should sink faster in the soda, will change the height of the eruption. You will crush Mentos candies and then use them to make Diet Coke geysers. 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 Explosions Introduction Have you ever seen the Diet Coke and Mentos experiment that is all over the Internet and wondered what makes the reaction work? You might think that there is some As the Mentos sinks to the bottom of the soda, it causes the quick production of carbon dioxide bubbles. These rising carbon dioxide bubbles react with more carbon dioxide still in the soda causing it to release as well. The pressure builds up and then creates the eruption or geyser of soda. Make This A Science Project: The results showed that Diet Coke created the most spectacular explosions with either fruit or mint Mentos, the fountains travelling a horizontal distance of up to 7 metres. Bubbles and soda will quickly shoot out of the bottle in a high fountain. The carbon dioxide molecules attach to the surfaces of the Mentos like they did in the cup of soda. All those Mentos in a lot of soda make a lot of bubbles that rise to the surface and push the soda out in a big woosh! .
