Glow in the Dark Jelly

 

To make the jelly glow in the dark we will be using tonic water. Tonic water contains quinine and quinine glows under a UV light.

For this activity we will be using boiling water so you will need an adult to help you!

The first thing that we are going to do is put our jelly cubes into our jug. We are then going to add one-part tonic water and one-part boiling water to the jelly cubes and stir it until it dissolves.  (If you look on the instructions on your jelly packet it will give you measurements on how much water to add)

You can then pour the jelly into your moulds and you will then need to wait for the jelly to cool and set 

Once your jelly has set you can turn off the lights and use your UV light. If you shine it at your jelly, it should glow in the dark. 

Some colours of jelly will glow to a greater or lesser amount than other colours so you may like to experiment with different colours of jelly and see what colour glows the best.
