Decorating paper with coloured bubbles

Mix some paint powder with a small amount of water.
Add dish washing liquid.
Add enough water to fill the container about a quarter.
Mix well.
Blow to form coloured bubbles.
Quickly place your paper on top of the bubbles (quickly because they do pop).
Repeat with other colours.
The result: Lovely home made wrapping paper.

It's also fun to use just the primary colours (yellow, red and blue) and see what colours you can create with the tiny bit of mixing that happens.
