Ingredients Method Notes

Ingredients
  

  • 1 cup distilled water
  • 4 tablespoons cornstarch
  • 1 tablespoon vegetable glycerin optional
  • 1 teaspoon white vinegar
  • Food coloring or liquid watercolor paints
  • A small saucepan
  • A wooden spoon
  • Heat-safe measuring spoons and cups
  • Silicone baking mat or parchment paper
  • Small glass jars or ramekins
  • Toothpicks or a fine brush
  • A straw or skewer
  • A soft cloth and gentle soap for clean-up

Method
 

  1. Measure ingredients. Combine 1 cup water and 4 tablespoons cornstarch in the saucepan, stirring until smooth.
  2. Heat slowly over medium-low. Stir constantly with a wooden spoon as the mix warms.
  3. Add a tablespoon of glycerin if you want softer pieces, and a teaspoon of vinegar for setting.
  4. Remove from heat when the mixture pulls away from the sides slightly and maintains a pudding-like texture.
  5. Let the mix cool for a minute. Fill small jars or ramekins with a thin layer of the bioplastic while it is still pourable.
  6. Add tiny drops of food coloring to each jar. Use 1 or 2 drops to start for soft swirls.
  7. Marble gently. Drag a toothpick or fine brush through the colors to create swirls and soft folds.
  8. Make a hanging hole while the pieces are wet by pushing a straw or skewer through the edge.
  9. Allow pieces to dry on a silicone mat or parchment in a warm, dry spot for 24 hours.
  10. Peel the suncatchers off gently when fully dry. Trim any uneven edges with scissors.
  11. Add cord or thin ribbon through the hole, knot it securely and hang near a window.
  12. Clean up calmly after the making ends by washing the saucepan and utensils with warm, soapy water.

Notes

For a slightly different texture, consider adapting the proportions of the ingredients. Keep the suncatchers dry and out of intense, direct heat to maintain their integrity over time.
