Did you have Shrinky Dinks as a child?!?! I did!! This project has some interesting potential! We did not use Shrinky Dink brand material. The product we used was Grafix Shrink Film. Same idea for the most part. After doing a Sharpie line drawing...the image was filled in with colored chalk dipped in water. If you don't have a classroom toaster oven...they are a good investment(polymer clay, salt dough, melting crayons..etc). The application of this product could be a jewelry lesson. If you cut the product to the right size...it could shrink down to necklace size. Use a hole punch before putting it into the oven...and you have the hole for the string once it is done. Image an Egyptian unit...and they could do a hieroglyph necklace!!
