An experiment called "lava in a cup" uses red food coloring, water, oil, and salt to create the illusion of lava. The food coloring is mixed with water in a cup, then oil is added which floats to the top since it does not mix with water. When salt is added, it carries the oil down and back up, resembling lava drops in a lava lamp.

1. My mom and I were looking for a science experiment then we found a brilliant experiment. It was
called “lava in a cup”. You need red food coloring, cup, oil, water and salt. First you mix the water and
food coloring in the cup then put oil which floats on the top of the water because oil does not mix with
water. So it rises to the top. Then put salt in. The salt carries the oil down with it. The salt dissolves but
the oil doesn't so it comes back up looking like the drops of a lava lamp. It is pretty cool. You should
try it! Attached is a picture of how it looks like:
