CHEMICAL REACTION EXCAVATION
In this fun and easy excavation activity for kids, we’re going to use a chemical reaction excavation that fizzes, bubbles, and pops to uncover our treasures we have hidden inside.
- 2 ounces of lemon juice
- 1 teaspoon of baking soda
- One square of toilet tissue
- Ziplock sandwich baggie
- Small items to "excavate" that can fit in the square of tissue. I like to use small tumbled stones. Little plastic aliens, dinosaurs, or other toys are also fun.

- Drop the packet of baking soda into the baggie.
- Quickly seal the baggie securely closed.
