Make your very own glow-in-the-dark chalk


Why not try a fun and spooky craft that you and your guardian can do together to light up dark nights — glow-in-the-dark chalk! Here’s how to make it:

What you'll need

Your guardians might have to help you get some of these items:

  • Glow-in-the-dark paint (found in a craft store)
  • Plastic ice cube tray
  • Plaster of Paris
  • Water
  • Mixing dish and spoon

Step 1

Once you and your guardian gather up all the materials, it's time to get started. First, pour about two tablespoons of paint into your mixing dish.

Step 2

Add cold water until the mixture is about half paint and half water. Stir well until the mixture is milky in texture.

Step 3

Slowly add the Plaster of Paris, bit by bit, stirring all the time. Keep adding until the mixture becomes firm and hard to stir. The chalk will be thick, but still wet to touch.

Step 4

Carefully spoon the mixture into sections of the ice cube tray. Be sure to pack it down hard so your chalk doesn’t crack! Keep filling up sections of the tray until you run out of mixture.

Step 5

Let your chalk dry and harden. This can take a day or two… Be patient — it's worth it!

Step 6

Pop your chalk out of the ice cube tray, and it’s ready to go! Draw your pictures on the sidewalk (or a piece of paper).

Then, shine a bright light on your art to ‘charge it up’. When you turn the light off, your pictures will glow in the dark.
