The science behind Shrinky Dinks! 🤏Which is really a byproduct of the vacuum form process as far as I can tell that someone figured out could be used for crafting and was cool and then eventually they started making the sheets intentionally. Interestingly, with the recycled number 6 plastic version of shrinky Dinks, you can get warping that you can't control depending on if they stretched the plastic in one direction or in both directions So it's good to do a lil test piece before going all out
