All you need to make this is:
An empty, clean canning jar and lid
Food Coloring (Optional)
Pour the cooking oil in the jar until it is about half full. (If you are using food coloring in the water, go ahead and add it.) Then, add the water to the jar, being careful not to overflow the jar. Put on the lid. Watch the cool reaction between the cooking oil and water.
For a cool effect, place a flashlight under the jar, as shown in the picture for your lava lamp to light up!
