Valentine Candy Science: Candy Heart Reactions

This idea came about because my son wants to mix everything with baking soda and vinegar lately. After we dissolved the candy hearts in water, Aiden asked to add some vinegar and baking soda to the hearts.

That brings us to today’s questions: What happens when you add candy hearts to vinegar? What happens when you add candy hearts to baking soda {and water}?

Materials:

  • candy hearts
  • containers
  • vinegar
  • baking soda
  • water

Procedure:

  1. Add 1/2 cup of vinegar to one container.
  2. Drop in a candy heart. Observe what happens.
  3. Mix together 1/2 tablespoon of baking soda to 1 cup of water.
  4. Add 1/2 cup of the baking soda and water solution to a second container.
  5. Drop in a candy heart. Observe what happens.

The candy heart started to dissolve a bit. {Here would be another fun experiment. Try to dissolve your candy hearts in different solvents. Mom to 2 Posh Lil Divas did this experiment with packing peanuts.}

When we added the candy heart to baking soda and water, we got a reaction. Watch the video to see what happens.
