STEP 2: Mix chalk colours.

Add 2 tablespoons of tempera paint to 1 cup of water and mix them together. Think carefully about the colours you would like your sidewalk chalk to be. 

STEP 3: Get a perfect consistency.

Stir in 2 cups of plaster of paris (per colour) until you get a thick consistency similar to the one of toothpaste. This mixture should be thick but still soft and liquid enough to be added to the cardboard tubes.

STEP 4: Put it in a pastry bag.

Transfer the coloured plaster into a pastry bag rapidly and snip the corner of the bag. You will need to work quickly as you don't want your mixture starting to dry. Squeeze into the cardboard tube making sure to tap the plaster mixture, this will help settle the mixture evenly.

Make sure the chalk is dry completely, if its damp once you start peeling off the tube and paper, leave it on a wire rack to make sure it drys out 100 percent before using it.

You'll get a soft and pastel chalk once it's ready, perfect to draw on sidewalks!
