Get ready to surprise your guests with this experiment. All it takes is a pack of Mentos® mint candy and a 2-liter bottle of diet cola to impress even the most skeptical scientist. This experiment is very messy so be sure to do it outside.

What Happens: Once the candy is dropped into the diet cola, all the soda will shoot out of the top of the bottle high into the air.


What You'll Need:

  • 1 2-liter bottle of diet cola (must be diet)
  • 1 pack of Mentos® mint candy (must be mint)
  • A thick piece of paper

Preparation:

All you need to do to prepare for this experiment is roll up your sleeves and get ready to take a big step back! Make sure everyone watching is standing away from the bottle.


At the Party:
  1. Drop the candy into the diet cola one at a time quickly. The best way to do this is to let the candy slide out of the wrapper into the bottle.
  2. Immediately and tightly cover the top of the bottle with a thick piece of paper.
  3. When you're ready, slide out the paper, take a big step back, and watch as the soda shoots into the air!
  4. This experiment is over quickly so you may want to have several packs of candy and several bottles of diet cola for an encore performance.
  5. See if the children can guess how high the soda is going to shoot out!
