Things needed :
· 2 paper cups
· Plaster of paris
· An object that you would like to use as the fossilized impression
v Flatten a ball of plasticine until it is about 2 cm thick while making sure the top is smooth.
v Put the plasticine inside the paper cup with the smooth side facing up. Carefully press the object you want to fossilize into the plasticine until it is partially buried.
v Carefully remove the object from the plasticine. An impression of the object should be left behind.
v Pour half cup of plaster of paris and stir until the mixture is smooth.
v Leave it for around 2 minutes.
v When the mixture has thickened, pour it on top of the plasticine in the other cup. Leave the mixture until the plaster has dried.
v When the plaster has fully dried, tear away the sides of the paper cup and take out the plasticine and plaster. Keep it in a warm dry place .
