Rainbows are everywhere at the moment to say a huge thank you to our amazing healthcare workers. This clever science experiment makes a lovely rainbow jar that you can place in your window for everyone to see!
The Science:
You can create different layers within your rainbow jar by using liquids that have different weights, or densities. This depends on how many molecules there are within the liquid – the more molecules, the heavier the liquid. We’ll be using the heaviest first to fill the bottom of the jar. Then, each liquid will be slightly lighter than the last!
