Ingredients & Materials

Bioplastic Base:

• ½ cup water

• 2 tbsp cornstarch

• 1 tbsp white vinegar

• 1 tbsp unflavored gelatin powder

Add-Ins for Color & Decoration:

• Natural or food-safe coloring (food dye, beet juice, turmeric, spirulina)

• Optional: fine glitter, flower petals, tissue paper bits

Tools:

• Non-stick surface (plastic sheet, silicone mat, or parchment paper)

• Hole punch

• String or suction hook for hanging

Instructions

Step 1: Make the Bioplastic Mixture

In a saucepan, whisk together the water, cornstarch, vinegar, and gelatin until smooth. Heat the mixture over low-medium heat, stirring constantly. The mixture will thicken quickly into a paste-like consistency. Remove from heat once it starts to gel.

Step 2: Color It!

Separate the gel into small bowls if using multiple colors. Mix in your natural or food-safe colorants. Stir well.

Step 3: Pour and Shape

Pour small amounts of the gel onto your non-stick surface in circles about 3–4 inches wide. Use a spoon to smooth and shape them. Add glitter, dried petals, or tissue pieces on top if desired.

Step 4: Let Dry

Allow the suncatchers to dry completely for 24–48 hours. The drying time depends on thickness and humidity.

Step 5: Punch Holes

Once fully dry and firm, use a hole punch to make a small hole near the top for hanging.

Step 6: Hang and Enjoy!

Thread with string or attach a suction hook and display in a sunny window to enjoy the colorful light show.

Storage Instructions

• Before Drying: Keep unused gel covered with plastic wrap and refrigerated for up to 1 day.

• After Drying: Store finished suncatchers flat in a dry place to prevent curling. Avoid damp areas as they may soften.

Display & Pairing Suggestions

• Hang in windows, on porches, or in classrooms.

• String several together to create a colorful mobile or garland.

• Pair with recycled craft projects for eco-themed décor.

• Add to gift wrap as reusable, decorative tags.

Pro Tips for Perfect Suncatchers

• Keep your surface flat – Use a baking tray to prevent gel from sliding.

• Use thin layers – Thick ones take longer to dry and may crack.

• Try natural dyes – Beet juice for red, turmeric for yellow, spinach water for green.

• Avoid over-mixing – Stir gently when adding color to preserve clarity.

• Seal for longevity – Lightly brush with a clear, eco-safe sealant if you want to keep them long-term.
