Looking for something fun for your children to do outdoors? Give them an activity to do that will let them use their imaginations. All you need is some sidewalk chalk and a sidewalk to use it on. Those of you who are crafty can try this recipe to make your own sidewalk chalk. Or, you could just use some of these suggestions about where to find inexpensive, pre-made, sidewalk chalk.
How to Make Sidewalk Chalk
Martha Stewart has a recipe that you can use to make sidewalk chalk in any color you want. You will need:
* Cardboard tubes (from the center of paper towels or toilet paper)
* Duct tape
* Freezer paper
* 32 ounce plastic containers (used yogurt containers)
* Tempera paint (in a variety of colors)
* 1 cup of water
* Mixing spoon
* 1 1/2 cups of Plaster of Paris
* Rubber spatula
* Cooling rack
She suggests that you start by cutting the cardboard tubes to about 5 1/2 inches. Use duct tape to seal one side of each tube. Insert a sheet of freezer paper inside each tube. It helps if you cut it to the right size first.
Get a plastic container. Mix 2 to 4 tablespoons of paint into the cup of water. Mix while slowly adding the Plaster of Paris to the water until completely combined. The mixture should be the same texture as frosting.
Fill each cardboard tube (that has been prepared as described above) with the Plaster of Paris mixture. Use the rubber spatula to make that a bit easier. Tap the tube on a work surface to release air bubbles.
The Plaster of Paris will set in about 30 minutes. You can remove the chalk from the tube after it has sat for about an hour. Squeeze the tube gently to check to see how hard it has become. After removing the chalk from the tube, set it on a cooling rack and let it dry for 24 hours before use.
Not interested in being crafty? You can still save money on sidewalk chalk. Start by looking for it in the nearest dollar store. Target might have some in their $1.00 racks. Educational stores may have some on sale just in time for summer.
Another idea is to see if you can track down where your children put the sidewalk chalk that they were using last year. See if it got mixed in with other art supplies.
