Smithsonian Perfect Cast Museum Craft Kits combine creativity, discovery, and learning in one exciting artistic journey. Start by mixing the Perfect Cast Casting Material in the 'mix and pour' bag and pour it into the molds. While it sets enjoy the fun, games and learning in the included activity booklet. Unmold your creation, paint the parts and set them onto the display background - now it's ready to show off on the easel. Smithsonian products bring fun and learning together by utilizing vibrant imagery and unique and relevant subject matter in a hands-on toy that truly engages a child!
