What’s it about?

Oil and water do not mix and hence they are described as ‘immiscible’. Oil has a much lower ‘density’ compared to water and hence it lies on the top of the water’s surface. Use the immiscibility of these liquids to make your own lava lamp in the following science experiment:

Topics covered

Density, Immiscible

What will I need?

  • LARGE GLASS JAR
  • VEGETABLE OIL
  • SALT
  • FOOD COLOURING
  • TAP WATER

How does it work?

Unfortunately, this section is only available in the e-book version of the project.

The oil floats on top of the water because it is less dense. The salt, in turn, is denser than the water and it weighs the oil down and makes it sink. Once the salt dissolves in the water, the oil slowly floats back up to the top of the water making beautiful patterns in the coloured water solution as it rises.
