How to make lava in a cup

If you are wondering on how to make your own lava, try this experiment. Find out what happens to the lava in the cup.

* A clear drinking glass
* 1/4 cup vegetable oil
* 1 teaspoon salt
* Water
* Food coloring

First, you have to fill the glass with 3/4 full of water. Then, add at least 5 drops of food coloring. You can use red if you want. It makes the lava look better.

Next, slowly pour vegetable oil into the cup. You can see how the water and oil separates. The oil floats on the water because it’s more lighter and less thick.

Lastly, to make the experiment work, put in the teaspoon of salt on top of the oil. Look at the lava moving up and down in the cup. If you want to keep it going, just add some more salt.

So this is the end of the experiment. Did you have fun? If the experiment didn’t work, keep trying again and again.
