Floating coloured water experiment

Science experiments are fun to do and a great way for children to learn. Try this simple science experiment that will teach your children about density.

What you need:

• Two glasses
• Salt
• Food colouring
• Water
• Spoon

Number of players:

Activity:

In the first glass, add a couple of teaspoons of salt.

In the second glass, add several drops of food colouring.

Slowly pour in warm tap water to both of the glasses.

Stir the salt water until the salt dissolves completely and stir the food colouring in the other glass until the food colouring mixes.

Slowly pour the coloured water into the salt water glass.

Watch to see how the coloured water rises to sit above the salt water.

Notes

• The coloured tap water will sit above the salted tap water because salt water is heavier than tap water.
