DIY dinosaur eggs. Mold salt dough around plastic dinosaurs, let harden and then break them open later for lots of dino fun! You need: 1 1/4 cup dirt, 1 1/4 cup flour, 3/4 cup salt, 1/2 cup sand, and water. This goes on my 'party ideas' list... what do you think as party favors? ( insert our own creation)
