14 crazy plastic sheets: 7 golden sheets, 7 silver sheets. From a simple sheet dedicated to this activity, draw and cut the shape you want in the crazy plastic and pass it to minutes in the oven. Your creation will shrink enormously: this is normal Crazy plastic hardens and loses up to 7 times its size when heated. Create key chains and other small items using this technique. You can use it with markers, colored pencils but also with acrylic paint. Very fun activity to do and watch it transform. Make your Christmas decorations with Diam's silver and gold crazy plastic. Contains 7 sheets + 7 sheets.
