Make a lava lamp

MATERIALS: -Food colouring. -Cooking oil -A plastic bottle -A funnel -Salt -Water
INSTRUCTIONS: 1. Put some water into the plastic bottle. 2. Add six drops of food colouring to the water. 3. Add a small quantity of cooking oil into the plastic bottle using a funnel. The cooking oil forms a layer on top of the water. 4. Mix everything. 5. Add some salt into the water. 6. Watch closely.
WHY? Oil and water don't mix because water is heavier. Oil makes a layer on the surface of the water. The salt sinks to the bottom and takes some oil with it. The salt dissolves in the water. Then, the oil floats back up to the surface.
