Transform classic baking soda science into something fit for Valentine’s Day with these super-fun fizzing hearts reactions!
My preschooler is a huge fan of vinegar and baking soda reactions. She always gets really excited when she sees me breaking out the vinegar and baking soda. She loves watching the fizzy reaction and playing in the mixture when it’s done reacting. This time, I decided to make the experiment Valentine’s Day themed with these fizzy hearts!
My kids had a blast with this simple experiment, and it was so much fun to see the hearts melt away.

- Baking soda
- Heart cookie cutter
- Red food coloring
- Pipettes (to control how much vinegar is used)
- Small dish
First, mix just enough baking soda with water to make a paste. Add a couple of drops of red food coloring and mix.
Place your heart cookie cutter into your dish and place the baking soda paste into the cookie cutter. Mash the paste with your fingers to mold it to the heart shape.
Carefully pull the heart cookie cutter away from the paste and you’ll be left with a heart.
Give the dish to your kids and give them a little dish of vinegar and a pipette.
Instruct the kids to use the pipette to scoop up vinegar and squeeze it onto the baking soda hearts. They will start to fizz and react.
Repeat the process until the reaction stops.
