So, gather your polystyrene trinkets, give them a little heat treatment, and witness their incredible transformation right before your eyes.

The Temptation of PET

Ah, PET – not to be confused with your furry friend! PET, which stands for polyethylene terephthalate, is another plastic that can handle the heat of the oven. Often used for beverage bottles, PET offers both transparency and shrinkage potential! So, if you’re in possession of PET trinkets and have an itch for some shrinkage shenanigans, fear not – the oven is your crafty ally!

Proceed with Caution!

Now that you’re armed with the knowledge of which plastics can shrink in the oven, it’s time to embark on your grand shrinking adventure!
