Requirements: smooth rocks, crayons (paper removed), oven, work board.


  1. Collect smooth rocks and clean them.
  2. Put them in an oven at 180 degrees for 15 – 20 minutes.
  3. Using heat proof gloves, take them out and place them on an appropriate work board (one that is heat proof and one you won’t be worried if crayon gets on).
  4. place the crayon on top of the rock and watch it melt. Place lots of different colours in layers to come up with your desired look.
