Pour enough plaster of paris in it to fill the impression, careful not to overfill and drip down the sides! Let the plaster sit a few hours (or even overnight) to set and harden. Remove the modeling clay from the now hardened plaster–this is your fossil!
Likewise, how do you make a fossil with plaster of Paris and clay? Mix a quarter of a cup of plaster of Paris with water, until it is quite runny. Pour the plaster of Paris over the modelling clay to a depth of around 2 centimetres. Let the plaster dry for 24 hours. Remove the plaster from the Tupperware and remove any leftover bits of clay.

- Small objects (small toy dinosaurs, seashells, starfish, etc.) to make impressions.
- An empty can, a butter knife, or a cookie cutter.
- Create a fossil mold but do not press the object very deeply into the clay.

As the water evaporates the minerals remain, eventually filling in the spaces left as the organism slowly decays.
Can you make your own fossils?
