Making a Plaster Print Mold

Plaster of Paris is messy, which means Scouts will enjoy it. You can use this versatile medium to make plaster molds and casts. This technique can be used to make shoe prints or tire track casts for a law enforcement themed meeting.  You could also use it to make a mold of animal tracks or a “fossil”.
