Method
- Step 1: Combine 1 cup of cornstarch, 2 tablespoons of vinegar, and 2 tablespoons of corn oil in a cooking pan. Stir thoroughly until the mixture becomes smooth and relatively free of lumps.
- Step 2: Place the pan over low heat and stir continuously until the mixture thickens and develops a soft, workable consistency. Do not leave the mixture unattended while heating.
- Step 3: Remove the pan from the heat and stir in a few drops of food coloring. Divide the mixture into portions first if you want to create multiple colors.
- Step 4: Place wax paper or a silicone mat on a flat surface. Position cookie cutters or flexible molds and carefully spoon the warm bioplastic mixture into them. Spread the mixture evenly for a smooth finish.
- Step 5: Transfer the shaped pieces to a baking sheet and allow them to dry at room temperature for at least 24 hours, or until they are completely hard.
- Step 6: Once completely dry, apply a thin coat of clear varnish if desired for a glossy finish. Allow the coating to dry completely.
- Step 7: Attach string or ribbon if desired and hang the finished suncatchers in a sunny window or another bright location where the colors can be illuminated by natural light.
Notes
Personalize your suncatchers with different colors and shapes. Potato or tapioca starch can be tested as alternatives, although results may vary. Biodegradable glitter and small leaves or flower petals can be added before the mixture hardens. Natural dyes such as beet juice or spinach can also be used for alternative colors. Adult supervision is recommended during heating and handling of the warm mixture.
