Cool Experiments For Kids
Here are a few experiments that involve salt:
1. Lava In A Cup
* A clear drinking glass
* 1/4 cup vegetable oil
* 1 teaspoon salt
* Water
* Food coloring (optional)
What you'll do:
* Fill the glass about 3/4 full of water
* Add about 5 drops of food coloring - I like red for the lava look
* Slowly pour the vegetable oil into the glass. See how the oil floats on top - cool huh? It gets better
* Now the fun part: Sprinkle the salt on top of the oil
* Watch blobs of lava move up and down in your glass
* If you liked that, add another teaspoon of salt to keep the effect going.
What you will need:
* 1 egg
* Water
* Salt
* A tall drinking glass
What you'll do
* Pour water into the glass until it is about half full
* Stir in lots of salt (about 6 tablespoons)
* Carefully pour in plain water until the glass is nearly full (be careful to not disturb or mix the salty water with the plain water).
* Gently lower the egg into the water and watch what happens.
