Some of the items needed for a homemade lava lamp are food coloring, a clear plastic or glass bottle, vegetable oil, water, and tablets of Alka-Seltzer.
In step one, one part water is measured to be mixed with three parts vegetable oil.
In step two, West Junior High School physical science teacher Lucinda Crenshaw and her 5-year-old son, Alex, add the water to three parts vegetable oil.
In step three, food coloring is added to the mixture of vegetable oil and water.
In step four, tablets of Alka-Seltzer should be crumbled.
In step five, Crenshaw’s daughter Alyssa, 12, adds the Alka-Seltzer to the mixture of vegetable oil, water and food coloring.
In step six, the cap should be placed back on the bottle, which should then be inverted and returned quickly to set on the table.
