Mix up the Plaster of Paris according to instructions. Place your mold onto a solid surface and pour a little of the plaster mix into the mold. Add your mini dinosaur into the mix, top up with plaster and leave to harden as per instructions. Give your little one a few tools and let them get excavating!
Freeze toy dinosaurs in large block of ice. Let the kids play archaeologist and dig them out with different tools (toothbrush, spoon, toy hammer/shovel, ect.). Boiling the water before freezing will resutl in clear ice!
