Remember Shrinky Dinks? Well did you know you can make your own Shrinky Dinks from styrofoam trays that are packaged with supermarket meat and veggies.
Preheat oven to 350 degrees.
Wash and dry your tray(s). Draw simple pictures on the bottom of the tray. Color pictures with permanent markers. Cut around the outline of each picture and place them on a cookie sheet or piece of aluminum foil.
Place in oven for a few minutes. When they stop shrinking take them out of the oven.
You can make your shrink art into jewelry by punching or cutting a hole in the top of each shape before putting them into the oven. When your shapes have cooled thread them onto yarn or colored string.
Note: You can use a Styrofoam plate instead of a meat tray however it will curl up so that your picture is inside but this is half the fun. Your end up with a secret picture inside a tube that you can see when you hold it up to your eye. You can cut away the turned up edge of the plate before placing it in the oven and it will not curl up.
