Make Your Own Sidewalk Chalk

Step 4 Clean-up!

Clean up is very important - and you don't want to rinse this stuff down your sink.  See how it's setting up in those molds?  It's going to do the same in your pipes!

Take a container like a small waste bin, and line it with a plastic bag.  Pour in some water, and use this as a sink to rinse everything - all materials, your hands, everything!    Let the plaster set up in the bottom, and the water will rise to the top.  Once it's settled, you can pour off the water from the top, leaving the plaster undisturbed.   Dispose of the bag.
