Plastic
Who didn’t spend hours as a kid playing with Shrinky Dinks? I was always in awe in front of the oven with the light on watching my creations shrink down into a hard piece of plastic. Now you can make your own! Just get yourself some #6 plastic. Most plastic containers you get from many bakeries and restaurants for food items “to go” are #6. You can make anything from jewelry, key chains, magnets,and push pins. The beauty of it all is watching them shrink! Link.
