Fossils are a great way to teach children about Noah’s Flood. This mold allows you to create15 plaster of paris replicas at a time so that children can paint them with watercolor or tempera paint. Each child will then have a fossil replica to take home! The molds can also be used with chocolate, gelatin (preferably before they are used with plaster), and even soap. However, liquids should be poured at a temperature of 180° (F) or below so that the mold will not melt. Before pouring anything edible into the molds, be sure to wash them thoroughly by hand, and not in the dishwasher.
