Coke and Mints Geyser Experiment

An expanded version of the traditional Diet Coke and Mentos Geyser Experiment.

Ingredients

  • 5 12 ounce Coke
  • 2 candies mentos
  • 2 candies LifeSaver Mints
  • 2 candies Altoids
  • 2 candies Ice Breakers
  • 5 post-its

Instructions

  1. Gather up your materials.

  2. Label each bottle of Coke using the post-it notes as follows:

    Bottle 1: LifeSavers

    Bottle 2: Altoids

    Bottle 3: Mentos

    Bottle 4: Icebreakers

    Bottle 5: Nothing

  3. Have your child drop the two candies into each bottle. It is more fun to do them one bottle at a time so you can watch each reaction.

  4. Ask them what they think happened and if they have other questions they could explore with a similar experiment.
