To make your own dinosaur fossils, you’ll need: toy dinosaurs; a small cup of instant coffee; 3/4 cup cold water, 1 cup flour, 6 tbsps of salt; a baking tray; and baking paper. Mix the instant coffee, flour, salt and water together to make a dough. (The coffee smells so good!) The dough needs to be wet, but not so wet that it sticks to your fingers.
