Make your own fossil :

Things needed :

             ·         Plasticine
             ·         2 paper cups
             ·         Plaster of paris
             ·         Water
             ·         An object that you would like to use as the fossilized impression

Instructions :

   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 .
