This was such a fun activity. Get your children to draw and write messages on white paper using a white crayon then paint over it using watercolours to reveal the message or picture. How does this work? The wax repels the water and water more readily bonds to itself. We decided to use this as an Easter related activity as Easter is not too far away. We drew some Easter eggs in white crayon then painted them with different watercolours. We also painted some watercolour rainbows.
