Did you know that there is a stew of plastic twice the size of Texas floating in the Pacific? In an attempt to reduce the amount of plastic that I use and throw away, I decided to make shrinky dinks out of used salad containers and document the steps.
Step 1: Eat Salad
You can make shrinky dinks out of plastic containers with the number 6 on them. These aren’t recyclable in New York so I can feel good about shrinky-dinking them. Most deli salad bars use this kind of plastic. Make sure to clean the container and cut the edges off before using.
Step 2: Draw an image onto the plastic
There are different techniques for drawing on shrinky dinks. I like to draw the image with a permanent marker on the right side of the shrinky dink. I made these by tracing images from Fakeproject Corp’s Graf Coloring book.
Step 3: Decorate the plastic
Sand the wrong side of the plastic with a fine grit sandpaper to give the colored pencil some texture to stick to. Color in the design with colored pencils. Since this is the wrong side, reverse your designs. I didn’t do this. The shrinky dinks pictured above are designed to replicate some real and fictional graffiti. My apologies to Borf and KR for shrinking their tags. Cut out your design.
Step 4: Bake in oven at 350 degrees
Baking plastic is generally not good for you. Don’t make shrinky dinks unless you are reconciled to this. I got the best results baking the plastic on a piece of printer paper placed on a cookie sheet with the sanded side facing down. Bake for 1 to 2 minutes in a conventional oven preheated to 350 degrees. Keep an eye on the plastic while it shrinks. The shrinky dink will curl up a lot and start to flatten out as it finishes shrinking. You can help flatten things with a metal spatula.
Step 5: Enjoy
Enjoy your shrinky dink. You can make a number of cool crafts with shrinky dinks including jewelry and kitchen magnets. See more pictures at my Flickr shrinky photo set. Link.
