Are you looking for a fun, easy activity for your kids this summer? Why not make geodes? A geode is a rock with a surprise inside. They are partially hollow inside and lined with sparkling mineral crystals. In nature, it is thought to take hundreds of millions of years to create. However, these imitation geodes will just take a week.
|Make your own geodes|
- 2 cups of water
- Eggs (as many as you want to make)
- Food coloring
Pour out the contents of the egg and discard.
Next, add 2 cups of water into a saucepan, add food coloring of your choice, and then mix together. Add Borax soap to the water until the water is well saturated with Borax (probably about 1 cup or more). Bring the mixture to a boil, remove from heat. (If you want to use multiple colors, divide the Borax water and then add the food coloring after boiling.)
Pour the water mixture into each egg.
The Science Behind The Experiment:
As the water evaporates from the eggs, Borax crystals deposit on the sides of the eggs creating geode eggs. The geode egg is very similar to an actual geode.
