Science experiment: Make rainbow paper
Put a splash of colour back into your imagination and make some rainbow paper. Mix and match some nail varnishes and have a play with the sunlight to see how bright the colours can be.
Number of players:
What you need:
- nail varnish
- black paper
Half fill a bowl with water.
Add a drop of nail varnish to the water and allow it time to spread out.
Dip a small black piece of paper and lift it out.
If you tilt the black paper, you should be able to see rainbows. Why?
Because when you dip the black piece of paper in the water, varnish is transferred onto it and when it is exposed to light, the light is reflected by the layers of varnish.
