Soap Crayons 

• 1/2 cup ivory snow soap flakes
  • or grate a bar of ivory soap to make your own flakes
• food colouring
• 1 Tbsp hot water
• old ice cube tray

Stir hot water into the soap flakes.

Spoon some of the mixture into an old margarine container and add a few drops of food coloring until it's the color you like.

Fill ice cube tray with soap and put in a warm breezy place to dry -- takes 48 hours to one week.

Take out of mold and let dry for another week before using.

Use crayons to draw on the side of the bathtub during bathtime.
