Melting Castles Baking Soda Science Play 

Last year, we tried a fun baking soda science snowflake search activity and had lots of fun! We are starting early with snowman this year since my son is eagerly awaiting the first real snow! Make sure to see our melting snowman baking soda science too!

Supplies Needed:

• sand castle molds
• baking soda
• vinegar
• water
• glitter 
• food coloring 
• baster or eye dropper

To Make Melting Castles: Add water to a good load of baking soda just until you get a crumbly but pack-able dough. It shouldn’t be runny or soupy. Mix in a load of glitter to make it sparkly! Pack the mixture into sand castle molds and pop in freezer until solid. I do recommend using small molds unless you want multiple children working together. I used one box of baking soda to fill our larger castle mold. You will want to run luke warm water around the outside of the container to help release the castle!

Winter, science, sensory, and fine motor play all in one easy activity using some basic kitchen cupboard ingredients! Use a turkey baster or an eye dropper or an even a small scoop or squeeze bottle. Really, whatever you have in the kitchen will work. Observe the awesome chemical reaction between baking soda and vinegar! Hint: I mix a little warm water into the vinegar to help the melting process!
