Here's how to make a homemade cup of lava:
. Salt (1 or more teaspoons)
.1/4 cup of olive or vegetable oil
.Food coloring (red, green, blue, and any other color you like)
.Large clear glass
1. Fill the glass with tap water, about 2/3rds of the way. You'll need to add the oil later, so make sure there is enough room left in the cup.
2. Pour the oil into the glass slowly. The oil will float on top of the water (don't try to mix it in).
3. Add several drops of different food coloring to the water and oil.
4. Slowly sprinkle 1 teaspoon of salt into the glass. Observe what happens to the oil and water mixture.
