FIZZY EASTER EGG EXCAVATIONS
- Large mixing bowl
- 6 Plastic eggs
- 1 lbs box of baking soda
- 6 clear plastic cups or small bowls
- Food coloring
- Tray or bin
- Excavations items. Tumbled stones are a huge hit! Legos, coins, and small plastic animals or dinosaurs are all fun options too!
Excavating Adventures Pro Tip: Instead of food coloring, I like to use bath coloring tablets. These are fun to watch fizz and add color to the water, but most importantly they do not stain hands and cloths like food coloring. You can also use the bath tabs as a learning experience and have your young Excavating Adventurer mix the colors to create new ones!
- Dump the box of baking soda into the mixing bowl.
- Add small amounts of water to the baking soda and stir with the spoon. You will not need very much water.
- Pack baking soda into one side of the plastic egg.
- Press your excavation item into the baking soda.
- Fill the other side of the egg with baking soda and press the ends of the eggs together.
- Open the egg and make sure you have a distinct egg shape. If not, pack some more baking soda into the egg.
- Place in the freezer for fifteen to twenty minutes. This will help the eggs hold their shape.
- Set up the cups in a tray or bin. This will help contain any messes.
- Fill each cup a little over halfway with vinegar.
- Add food coloring or bath color tabs to each cup of vinegar.
- Remove the Fizzy Easter Egg Excavations and allow your Excavating Adventurer to place them in the vinegar cups and watch as the eggs fizz, bubble, and foam.
- Be sure to rinse off the excavation items after they have been discovered.
