Our lightbulb science experiment was set up beside a lava lamp experiment at the Science Fair. The boys have been wanting to make them ever since.
Here’s the recipe:
-Pour water into the bottle until it is two thirds full.
-Add a few drops of food colouring to the water.
-Pour in a small quantity of oil, just enough to form a layer on top of the water.
-Sprinkle a few pinches of salt onto the oil and watch what happens.
-Keep adding salt to make your experiment last longer.

Very fun. I want to know how much real time elapsed in the fast-forwarded first portion of your video. Lots of activity!
