We had a lovely time making fossil imprints yesterday. We used a variety of materials to investigate which produced the best results; clay, air drying putty, plaster of Paris and ground coffee dough!
To make the coffee dough we mixed a cup of ground coffee granules with a cup of flour, half a cup of salt and half a cup of water. Then we just kneaded it, rolled it out and made out imprints!
They are all drying on our windowsills now – they look great!
