To Make Melting Castles: Add water to a good load of baking soda 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 it in the 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 lukewarm water around the outside of the container to help release the castle!

Hint: I mix a little warm water into the vinegar to help the melting process!
