Posted 2013-06-22 by Jane Street ⇒ follow

This colourful sensory activity will appeal to anyone who likes messing, mixing and making potions. Make your own shimmery colourful crystals and have fun exploring colour mixing.

Time: 30 minutes
Age: Under 5's
Level: Easy

Materials

Rock salt

Food colouring

Aluminium foil

Baking tray and oven

Jug of water

Several clear glasses or jars

Spoons

Stirrers (we used chopsticks)

Newspaper

Rock salt makes scoopable colourful crystals

Method

Bend some aluminium foil into shallow cups, one for each colour. Place on the baking tray

Add a handful of rock salt to each foil cup

Add a capful of different coloured food colouring to each one and mix around each pouch until the salt is covered in colouring

Ready to mix the colour through then dry in the oven

Bake in the oven until dried out and shimmery (about 10 minutes in an oven at 150 degrees)

The colourful crystals are shimmery

Put down plenty of newspaper then set out a jug of water, lots of glasses or jars with stirrers and the cups of coloured salt with a spoon for each colour.

Ready to get stuck in

Let the children decide how much water to pour into each glass then scoop spoonfuls of the colourful crystals into the glasses of water as they choose. The salt crystals make interesting tinkling sounds as they are stirred in the water.

Let the children top up the glasses with more water from the jug if they wish to.

With older children, explore colour mixing and try to predict how the colour will change before you add a new spoonful of crystals.

Watch out as the food colouring will stain hands and clothes and may make quite a bit of mess!
