Description

Sidewalk chalk is a favorite way to create art during the warmer months.
We have had lots of fun creating different chalk recipes over the years, too. This next chalk activity was a real "blast" of a good time! Are you ready for take off?


Resources

Materials
Corn starch
Water
Food coloring
Film canisters
Alka-seltzer

Instructions

it is easier to mix up a batch of sidewalk chalk and then pour it into the film canisters as we played, adding color to the rockets as we went.
Begin by mixing equal parts of water and corn starch in a bowl or container
This will give you your base sidewalk chalk. Once well mixed pour the chalk mixture into the film canisters, filling them roughly 1/3 of the way. You can alter the amount of chalk you add as you play to produce different art effects.
Add a few drops of food coloring to the canisters and mix well.
Your rockets are now ready for take off!
You will want to set off one chalk rocket at a time. Take a tablet of alka seltzer and break it into 3-4 pieces.
Toss the pieces into the canister, quickly secure the lid, and then place the rocket on the ground. Now stand back!
In a matter of seconds the rocket will fly high into the air, leaving a blast of sidewalk paint all over the pavement below.
