Experiments in Shrinking Black #6 Plastic

We had a huge black plastic catering tray (and clear lid) that were both #6 plastic, ideal for shrinking in the oven. I did a few little experiments with the clear lid (not worth posting – they warped badly!) and then cut into the black tray. It was thicker, and also I have never seen anyone post about using the black plastic before, so I wasn’t sure what to expect!

The ridges on the tray made me think of moustaches, so I cut a couple out and punched holes in them. The black plastic behaved differently than the clear plastic. Clear plastic shrinks to about 1/3 its original size. The black plastic warped a bit, and didn’t shrink much.

I still had time to string it into a moustache necklace and take a quick pic!
