This is what you need:
- white board
- plate
- water
- straw
- possibly tablespoon
Find a smooth plate, without many scratches. Draw a shape with the whiteboard marker. Let the figure dry.
Carefully pour water into the plate. Slowly the figure will loosen and float to the top. You can help by moving the plate a little or gently stirring the water.
If the marker won't come off completely from the plate, you can draw on the back of a tablespoon or ladle, and slowly lower it into a bowl of water.
If your drawing curls up, breathe with your belly and give it time. It will unfold again.
