Props –Things For Adults To Make
The following recipe is inedible. It
is great to use for demonstrating different qualities of animals or are just
fun as a gathering activity for programs. The ingredients listed in each recipe
are non-toxic but not to be eaten.
1 1/2 cup plaster of paris
½ Cup of Water
2 to 3 tablespoons washable tempera paint
(powdered or liquid tempera work equally well)
Large plastic mixing containers (we
used recycled margarine tubs)
Toilet tissue tubes (or gift wrap
tubes) cut in short sections
Duct tape or masking tape
Prepare your chalk molds by covering one end of each tissue
tube with duct tape or masking tape. Set aside until ready to pour
mixture into tubes. Pour water into your mixing container. Sprinkle the plaster
of Paris powder into the water a little at a time (about 1 1/2 cups).
Stir thoroughly, until the mixture is as thick as pudding. Add tempera paint to
the plaster mixture and stir until well blended. Pour the colored plaster into
the tissue tubes. Gently tap the side of each tube to get rid of air
bubbles. Let dry for one to two days, peel off the mold and create at will.
**NOTES: This will be a messy project, so I recommend doing
it outside. Also, Plaster of Paris thickens quickly, so you can’t take a long
time preparing you’re mixture. You don’t need to rush but don’t stop in the
middle of mixing. This stuff won't work on chalkboards, it's too hard, but it
works great on sidewalks and lasts much longer than store bought stuff.
