Make your own “Shrinky Dinks” with #6 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.

    Is it toxic to heat up this plastic in your oven?

    it’s only for a minute, so it’s probably fine. run the kitchen fan/exhuast – but i don’t think it will matter.

    I tried this with some designs drawn on polystyrene (recycle code #6) plates (Hefty Serve and Store Party variety), just as described, and had no success. Tried with varying thicknesses of foil, using a baking sheet and not, letting the plastic “cook” for longer than 1 minute, and all I got was 20% shrinkage at most, a topology like a wilted slice of American cheese, and no discernible increase in thickness. Perhaps not all polystyrenes are alike? Suggestions?
