We’ve made sidewalk paint out of corn starch, water, and food coloring many times. Did you know that if you add an antacid tablet and capture it in a small container that the gasses will build up and explode? I saw this idea in a kids magazine years ago and it was so easy!
Here’s how to do it!
Sidewalk Paint Rockets
Fill with water until canister is 1/3 full. Stir.
Place the canister on the ground with plenty of clearance space. QUICKLY add the antacid tablet pieces, snap the lid onto the canister, turn it over so that the lid is against the ground, and RUN!
