How to make a snowfall in a lava-lamp?
Reagents and equipment: white gouache, baby oil, baking soda, citric acid, glass, water, spoon.
Mix some white gouache with water in a glass. Pour the solution into a bigger glass and pour baby oil gently down the wall of the glass. Add baking soda and citric acid — white bubbles are formed!
The citric acid reacts with the baking soda, releasing bubbles of carbon dioxide. It rises through the oil layer and pulls the tinted water along with it. Looks like a snowstorm has begun in the glass!

Safety precautions: perform this experiment only under adult supervision.
