You will need: paper or a square of pale coloured fabric, 1 piece of kitchen towel, a hammer and sellotape. This will need to be done on a flat, hard surface.
Go and collect some brightly coloured flowers (pansies, marigolds, grape hyacinths work well) and a couple of interesting shaped leaves.
Place them carefully on your fabric/paper. Make sure they are where you want them. Place the kitchen towel over the top. Tape them down so they don't move about. Now for the fun part, bash! Take the hammer and bash over and over again. You should start to see the pattern of the flower showing through the kitchen towel. Keep bashing!
Slowly unpeel the kitchen towel and look at the print you have made.
