Warm water dissolves a candy cane the quickest. Water doesn’t dissolve candy canes more quickly if additives like sugar or salt are added to it. Milk and juice dissolve candy slower than water. Water temperature affects how quickly candy canes melt because warm water has faster molecules that melt the candy cane more quickly.

To make Magic Snow, you’ll need the following supplies:

  • Cold water
  • Cold baking soda
  • Vinegar
  • Bowl or container.

Pour four cups of baking soda into the bowl and add a bit of vinegar. Then slowly pour cold water into the bowl and mix until you get the desired snow-like texture.
