See if candy dissolves faster in hot or cold water.
Red Skittles in hot water dissolve faster
than orange Skittles in ice water
What you need:
- Identical pieces of candy
- Hot and cold water
- Cups
What to do:
- Fill one cup with hot tap water and one with cold water (for better results, add ice cubes).
- Put one candy in the hot cup and one in the cold cup.
- Watch to see which dissolves faster.
What’s happening:
Because molecules move faster when it’s hot, the candy in hot water dissolves much faster. The candy in ice water might take all night to dissolve.
With chocolate, the difference is even more impressive. Since the cocoa butter in chocolate doesn't dissolve in water, chocolate placed in cold water just sits there. But chocolate in hot water melts and mixes with the water.
