Fizzing heart ❤️
Materials required:
- Baking soda
- water
- White vinegar
- coloring food
- eye dropper
- plastic bin
The day before, mix baking soda, water and food coloring until you get a paste that you can mold into a heart shape. The next day pour some white vinegar in a bowl and ask your child to use an eye dropper to put vinegar on the heart. You can hide some little heart in your baking soda heart for more fun.
