1. For each color, pour gelatin powder into a separate bowl or shallow pan.
2. Add 1¼ cups boiling hot water to each color and stir until completely dissolved. (Do not add cold water for this version.)
3. Refrigerate each color until fully set, about 2–3 hours.
4. Once set, cut each color into small squares. Use a spatula to lift them out.
5. Arrange squares on a platter in rainbow order: red, orange, yellow, green, blue.
6. Add whipped cream “clouds” at one end of the rainbow. If desired, add gold chocolate coins near the clouds for a “pot of gold” look.

Kid-Friendly Tips

• Kids can help sort colors and build the rainbow pattern
• Adults should handle boiling water and carrying pans to the fridge
• Use cookie cutters for fun shapes (stars, hearts) instead of squares

Easy Variations

• Add purple: Include a purple gelatin box for a fuller rainbow
• Layered rainbow: Pour one color into a pan, chill until set, then add the next color on top
• Fruit rainbow: Mix in small fruit pieces (like mandarin oranges or berries) after gelatin cools slightly

Notes

Let gelatin cool slightly (still liquid) before refrigerating if using plastic bowls to avoid warping. Store leftovers covered in the refrigerator and serve within 3–4 days for best texture.
