Two days ago I went to see a science show. Vancover, BC Science Center had a science tour across BC and it came to Nelson. The neatest thing in the show was the "Candy Geyser". They first got 2 liters of Diet Coke. Then they taped 3 Mentos candies to a string. There was a hole poked in the top of the bottle's lid. They strung the string threw the coke lid so that the Mentoes were inside the lid .When they put the lid on the coke ( not screwing the lid on) and dropping the Mentoes into the pop. The soda then shot up all the way up to the ceiling of the gym.How messy, they had to try to figure out how to clean the ceiling after the show. LOL
Here is why it does what it does.
CANDY GEYSER Stand back for an awesome eruption! Mentos candies dropped into a two litre carbonated soda bottle create an explosive chemical reaction. Guar gum in the candy disrupts the connections between water molecules that keep the carbon dioxide is free to start joining up on the rough surface of the candy, bubbles form very quickly making an awesome soda eruption!
Cool! We did that too! Go to my blog to see the pics! (Their on a non recent one so you'll have to look for them) I hear diet coke works the best!
