Homemade Sidewalk Chalk

Need another idea for your silicone molds?  How about some homemade sidewalk chalk?

First get all of your supplies collected. 

1. Molds of your choice
2. Plaster of Paris
3. Powdered tempra paint in color of choice
4. Bowl for mixing the chalk
5. Water
6. Spoon
7. Knife 

Mix together 1 cup of plaster of paris with 3/4 cup of water.  Add colored tempra paint to get desired color.  Blend well and let stand for a  few minutes.  Line up your molds so you are ready to pour.

Pour mixture into the molds.  Just a little hint here - DO NOT lift the mold and drop to get out air bubbles like you do with chocolate.  This could result in a huge mess and sidewalk chalk mixture all over your laptop.  Of course - I'm just guessing that could happen?

Allow the chalk to set and then remove from the mold.  I was able to remove them from the molds after 45 minutes.  Then set the chalk pieces aside to dry thoroughly - this takes approximately 24 hours.

Now, I'm all ready for warm weather to get here so I can go out and play!  In the meantime, Jax and Mari ran outside for a quick test.  Future note -- add a little extra color -- the pink was a tad light.  

Mari was cold and wasn't staying outside any longer!
