How Does the Candy Cane Experiment Work
This candy cane experiment works through dissolution and diffusion:
Dissolution: When warm water contacts the candy cane, its sugar and color coatings dissolve into the water.
Warm water accelerates this process because it increases molecular motion, breaking down the candy faster.

Diffusion: The dissolved color and sugar molecules spread from areas of high concentration (around the candy cane) to lower concentrations in the water.
This creates the colorful patterns as the dyes disperse outward.

By keeping the water layer thin and the plate steady, you allow the diffusion patterns to form clearly without interruption.
Materials Needed
- White plate (not paper)
- Warm water
- Cup
- Rainbow Candy cane (or colorful candy cane)Â
Candy Cane Experiment Directions
Place the candy cane at the center of a flat plate. A slight tilt may affect the results, but it’s fine as long as the table remains steady.
Note: Avoid bumping the setup to keep the water and color patterns undisturbed.
Pour a thin layer of warm water onto the plate, ensuring it reaches beneath the candy cane without fully submerging it.
