Detailed explanation-1: -Cover the bottom of your Tupperware container with modelling clay to a depth of around 2 centimetres. Press a few plastic animals, shells, or whatever else you’d like to fossilise, into the clay. Remove the objects. This should leave an imprint of the object in the clay.
Detailed explanation-2: -Place the clay on a paper towel or plate with your name on it. Use your shell (or other object to fossilize) and push it into the clay to make a deep imprint. Remove the object and make sure the imprint is clean. Pour enough plaster of paris in it to fill the impression, careful not to overfill and drip down the sides!
Detailed explanation-3: -1 cup of used coffee grounds. ½ cup cold coffee. 1 cup of all-purpose flour. ½ cup of salt. Wax paper. Mixing bowls. Small objects (small toy dinosaurs, seashells, starfish, etc.) to make impressions. An empty can, a butter knife, or a cookie cutter. 20-Mar-2020
