Science is Fun at Nibley Park

students observes Mentos in diet soda experimentScience lessons are fun in fifth grade. Students from Ms. Deaver’s and Ms. Coon’s classroom went outside for science to watch a physical change in matter. Take one liter of diet soda, add one Mentos mint, and STAND BACK!

The amazing burst of bubbles when you add a Mentos candy to a liter of diet soda pop is not a chemical reaction, but a physical one. Soda is full of carbon dioxide gas, which has bonds with water. The bumpy surface of the Mento candy breaks the bonds between the water and the carbon dioxide and all those fabulous bubbles burst. It's a good thing science was outside today!
