In this video, you can use your kitchen stuff to make an incredible rainbow in a bottle for your children.
The experiment is an exciting stepping stone for children to learn about the density of matter through observing rainbow phenomena, from which you can guide your children to explain density. The density of a solution/object affects its buoyancy in another solution. If its density is higher than the solution’s, it sinks; and vice versa, if its density if lower than the solution’s, it floats.
