I love these, I'm saving them for one of those days where my kids are driving me up the wall with boredom. Most of all I love them for a party, they are so versatile you can use them for just about any kids party. They would be perfect to hide pirate treasure in or fairy treasure or to be collected by the pick up trucks and take to the treasure freeing yard at a construction party.
Enjoy, they are a lot of fun.
Magic FIZZING Rocks
MAGIC Treasure Rocks Materials
- Baking Soda
- Food Coloring or washable watercolors
Add the desired amount of baking soda to a bowl. Add a few drops of food coloring if color is desired. Then slowly add water and mix. SLOWLY add more water until the mixture is damp and mold-able, but not too wet. It is easy to add too much water, so you definitely want to add it slowly. If you do accidentally add too much water just add a touch more baking soda.
Once mixed mold the baking soda dough into balls, hiding treasures inside. Then lay the baking soda rocks out on a cookie sheet or similar to dry. Drying will take roughly 24 hours. Once dry you can either give them right to your child, OR you can bury them outside and let your child go on a treasure hunt.
To free the treasure either spray the rock with vinegar for a slow fizz or for a fast fizz eruption put the rock into a bowl of vinegar.
