Chalk It Up to a Good Time

In nice weather often sees children and families playing outdoors. A favorite pastime of many is using sidewalk chalk. Chalk purchased from the store works just fine, but there are a couple of fun and unique types of sidewalk chalk you can make at home.
The first is glow in the dark chalk. You will need: a bucket or jar, spoon, ice cube tray or other mold, petroleum jelly, plaster, water, food coloring gel or liquid watercolor, and glow in the dark paint.
Coat your ice cube tray or mold with petroleum jelly and set aside. For mixing it is best to use a bucket or jar that you no longer need, as it is highly likely you will need to discard it after mixing the ingredients. Use a spoon to mix 1 Cup of plaster, ½ Cup of water, 3 Tablespoons of the food coloring gel or liquid watercolor, and 4 Tablespoons of your glow in the dark paint. When all the ingredients are completely mixed, spoon them into your ice cube tray or mold. Place in a cool, dry place to dry overnight. Do not freeze! When dry, you may take them out of the mold and begin using them to make glow in the dark art on the sidewalk. The chalk will absorb the sunlight and glow for a short time after dark.
For our small artists who may not quite have the fine motor skills for chalk sticks you can make sidewalk chalk paint. You will need: cornstarch, water, food coloring, a container, spoon (optional), and something to paint with.
In your container, mix the cornstarch and water, begin with a 1:1 ratio and mix with a spoon, your paintbrush, or even your hands! Add a few drops of food coloring and continue mixing. If the chalk paint is too thick, add a little more water, or if it is too runny, add a bit of cornstarch, just try for the consistency you want. Next, take it outside and use a paintbrush to paint on your sidewalk.
Just like the store-bought chalk, neither of these are permanent, but both methods will take a few washes to fully come off the sidewalk. Have fun, and remember to wear sunscreen and drink water when playing outside.
