You will need:
A roll of plastic wrap paper
Paints in bowls
Spoons for each bowl
Place paper on the table and using a small spoon dribble different coloured paints.
Place a sheet of plastic cling wrap over the paint (make sure the cling wrap covers the whole surface).
Flatten the cling wrap with your hands on the paper until smooth.
Peel the cling wrap from the paper carefully and slowly.
Leave the painting to dry.
