Stuff to get: Plaster of Paris, tempura pain (preferably neon), silicone pop mold, wood craft sticks, plastic cups, and plastic spoons. Cold water, scissors and measuring cups. You can find all the supplies you need at Walmart.
*Before you begin please read these: Do not put the plaster down your drain. It will harden in the pipes and cause lots of damage. Please does this project outside, it can be very messy. Chill the water in your fridge for 30 minutes before starting. Older children can help, but probably not a good idea for the younger ones.
- First you need to cut down your craft sticks about 3″ long.
- Use one plastic cup for each color you want to make.
- Fill each plastic cup with 1/3 cup cold water.
- Add 2 Tbsp. of tempura paint in each plastic cup. (you can mix colors to get a certain one).
- Use the spoons to gently stir the water and paint. Don’t worry if the mixture is still a little chunky, it’ll smooth out later.
- Add 2/3 cup Plaster of Paris to each plastic cup. This is the messy part.
- Stir until combined. It should look like yogurt when your done.
- Carefully pour your colors into the silicone mold. Gently tap the mold onto the work surface, to get all the air bubbles out.
- After about two minutes, the plaster will have began firming up. Insert your craft sticks (the cut side down) into the middle of the chalk. They should be pretty easy to place.
- Setting them in the hot sun is a good way for them to cure very quickly. After an hour, you can carefully remove them from the mold. Leave them in the sun to keep drying.
- Wait a full 24 hours for them to cure and be used. Just to make sure they are dried all the way.
The sidewalk chalk pops are a lot of fun for little ones. Plus the sticks make it easier, so no one hurts there fingers or knuckles when they are almost out.
