In just a few minutes, usually 1 to 3, they begin to curl, twist, and then flatten as they shrink. A standard hole punch works well and shrinks to just the right size for a jump ring if you punch it before baking.

Shrink to About a Third of Their Size

This humble beginning sparked a crafting revolution, showcasing the powerful potential of parental creativity. In a small Wisconsin kitchen in 1973, two imaginative mothers, Betty Morris and Kate Bloomberg, embarked on a creative journey. Look for his cute photo for sciencey insight from Dr. John! Slower heating and a lower temperature for a longer time would lessen the whitening but some pieces may have too much of the additives that lead to void formation. This cup is white since the polystyrene had an intention volatile additive and the material was heated in controlled fashion during forming Into the cup shape.

So now that we had our Shrinky Dink mojo on – I was completely out of my Panera stash — I got desperate and tried shrinking another plastic box that I saved from the Daddy Daughter Dance corsage. If it has a 6 in it, you’re good to go. In case you’re wondering, that’s about 4 cents per second. A 3 year old will blast through coloring this package in approximately 38 seconds a piece of plastic and then be ready to shrink them in the oven.

The shrink plastic is quite brittle, so it is best to use small, sharp scissors for this, though most rough edges will be hidden once shrunk. We have had the best results by keeping the bulk of the design as outlines, and only filling some of the shapes with solid colour. Start by securing your template on a solid surface – we are using the ceramic tile we use with our heat gun – and attaching the shrink plastic sheet on top of it. Line artwork works best, and we have found that embroidery templates or colouring sheets are a great place to find the shapes that work well as outlines. If it still is not flat, hear it up again and place a ceramic tile or other flat heat-proof object on top of it while it cools.

If you chose not to outline the shrinky dink in black ink then you can just double-check the lines around your fire flames are solid. For mother’s day try making cute shrinky dink rings for the moms and grandmothers you know and love for a really perfect keepsake gift. The reason you need to flip the plastic piece over is to make sure when coloring in the flame you don’t drag over any black ink onto the red, orange, or yellow. You could even add blue to your flame at the bottom! For our own shrinky dinks, we went with the regular red, orange, and yellow. Each fire flame will need half of an original size 8 x 10 sheet of Shrinky Dink paper.

In the real world, this branch of science is being used in the manufacture of solar cells, high-density displays and chemical sensors. It’s a branch of science that looks at the properties of materials on very small scales. By nature, the polymer chains within the polystyrene are bunched up and randomly clumped together, but the heating, rolling and cooling process forces them to straighten out and get into a more orderly configuration. When manufactured, raw polystyrene is heated, rolled out into thin sheets and then rapidly cooled so that it can retain its shape. The sheets of plastic you get in a Shrinky Dinks kit is polystyrene—the same stuff as recycled plastic #6, which is commonly used for those clear clamshell containers you see in cafeterias. You were then supposed to play shrinky dink plastic with whatever it was you made, but frankly, the entertainment value was all in coloring pictures of your favorite cartoon characters and then watching them crinkle up in the oven and then mysteriously lie down flat again.

The basic idea is you decorate a piece of polystyrene (plastic) and then bake it so it shrinks down in size. Shrinky Dinks can be used for jewelry, keychains, pins, and lots of other projects.

Take fine sandpaper and lightly scratch the entire surface of the plastic so it’s rough and will hold the color of your medium. This makes a wonderful product but they still get to be creative. Let the kids make any designs they wish and then cut them into shapes for them after. You could lay the sheet on a coloring book page or some of our free printable patterns and first draw a heart onto the sheet. I stink at freehand cutting, but if you are creative with that or have some large punches, you can cut out your own shapes as I did here.

Tips for making your Back to School Shrinky Dinks

I have also made some Boho denim earrings that you might want to check out. With this method, I melt plastic bottles over naked flames and have made some cool mini faux succulents. As mentioned at the beginning, many everyday plastics can be shrunk. If I had to choose a favourite, it would be the white Marimekko style flowers; I have the perfect floral dress to go with them. As the plastic shapes shrink, they will curl up and flatten.

These are my best guesses as I have not used shrinky dinks in the exact way you are. How do you make them opaque so you’re not struggling reading through one and seeing another when there are multiples on the same o ring? Shrinky dinks don’t tend to turn out perfect though. So, if you need perfectly straight lines or corners to fit into a tiny frame or something that might be tricky, but you could sand it down (with fine grit sandpaper). I will say, they probably aren’t perfect rectangles.
