Description

A vibrant and engaging science experiment that explores the interplay of ice, salt, and color, perfect for kids and adults.


Ingredients

  • Ice cube trays
  • Water
  • Food coloring (multiple colors)
  • Salt
  • Large shallow pan or tray
  • Spoons (for mixing)
  • Safety goggles (optional)
  • Dropper (optional, for precise coloring)

Instructions

  1. Fill ice cube trays with water.
  2. Add drops of food coloring to each compartment, mixing for desired color intensity.
  3. Freeze the trays for several hours until solid.
  4. Once frozen, remove the ice cubes from the trays.
  5. Arrange the colorful ice cubes in a large shallow pan or tray.
  6. Sprinkle salt generously over the ice cubes.
  7. Watch closely as the salt begins to react with the ice, causing it to crack and melt.
  8. Listen for the crackling and see how the colors start to blend.
  9. Use a dropper to add more water if you want to create a slick, colorful puddle beneath the ice.
  10. Use your spoons to mix the ice and colors.
  11. Experiment with different amounts of salt and observe the differences.

Notes

Try using flavored drink mixes instead of food coloring for a scented twist or add glitter for extra sparkle.
