We have been having lots of fun playing and exploring with sidewalk chalk this Summer. Today, Rosie asked if we could make exploding chalk. I thought that sounded SO fun, so we experimented a bit, and these super amazing chalk rockets were the outcome of our trails.
Sidewalk chalk is the perfect way to create art in the warmer months. We have had a blast creating all different play times using a variety of chalk recipes this Summer. These exploding chalk rockets were so fun we have already done this activity THREE times since the other day. Are you ready to give it a try?
MethodYou want to begin by filling each film canister 1/3 of the way with liquid sidewalk chalk. We mixed our chalk right in the canister. This worked great and allowed us to create a variety of colors.
If you are unfamiliar with how to make liquid sidewalk chalk it is basically just a mixture of corn starch, water, and liquid water colors. You can also use food coloring. Exact measurements are not needed. We basically just filled each canister 1/4 of the way with corn starch and then added enough water to make a liquid chalk. ( More detailed instructions for making liquid chalk can be found here)
Once your chalk colors are mixed you want to set one rocket off at a time. Take one alka-seltzer tablet and break it into 3-4 pieces. Drop the pieces into the canister, and then quickly pop the top on and flip the canister over. Then stand back

Lots of beautiful art splatters after setting off multiple rockets
