Rainbow sand in a jar

When I was in primary school I remember my dad went on a business trip to some desert location and came back with a small jar of different coloured sands. I thought this was the coollest thing ever and kept it on display in my bedroom for years.

With this in mind, I helped the kids make rainbow sand in a jar. We used the following materials:

• jars
• sand
• food colouring
• spoons
• plastic sandwich bags.

It's pretty easy to make the coloured sand. Just scoop a few spoonfuls of sand into a plastic bag. Add between 5 and 10 drops of food colouring. Seal the bag then shake it or massage it until all the sand changes colour.

We made four bags of different coloured sand - blue, green, red and yellow.

To finish off, scoop the coloured sand into your jar and enjoy!
