Cheery sidewalk chalk

This homemade chalk will light up even the dingiest and dreariest of pavements! Make some together, and bring a new lease of life to your neighbourhood slab.

Instructions: making your chalk

  1. Tape off the bottom of your toilet roll tubes with masking tape. Get your child to inspect the bottom of the tube to make sure there are no holes for the chalky mixture to leak through. If they spot any gaps, ask them to cover them up with some of the masking tape.
  2. Line the insides of the tubes with baking paper, and place on a baking tray or a dish lined with baking paper. Set aside.
  3. Add approximately half a cup of plaster of Paris powder to a quarter cup of water. Make sure you do it in this order.
  4. Add one heaped tablespoon of powdered tempera paint and mix thoroughly, making sure there are no lumps. Work quickly before it gets too thick and gloopy. If in doubt, add some more water. The ideal consistency should remind you of pancake mix.
  5. Pour the mixture into the tubes and let it sit for a few hours.
  6. Once the plaster has set, it’s time to get creative!

Top tip: To make rainbow chalk, allow each layer to set slightly before pouring the next layer.

 

Instructions: using your chalk 

  1. Find a plot of ugly, barren, grey pavement. Look how sad and empty it looks! What can you do to change that?
  2. Get your child to take out their chalk.
  3. Ask them to add a rainbow to the ground.
  4. Do a little happy dance together, and bask in your DIY sunshine.
  5. Once you’re done with the rainbow, try to add to the pavement picture. What might be waiting at the end of the rainbow? Are there any lurking leprechauns? Any pots of gold? How about dragons? Invent a little scene to cheer up any passers-by.
