Growing Gummy Bears

The elf left gummy bears soaking in cups overnight, and in the morning one has grown huge. The kids compare the cups and guess why.

Instructions

Set out three clear cups: plain water, salt water (a spoonful of salt stirred in), and one empty cup.
Drop one gummy bear into each cup.
Put one more gummy bear on a paper beside the cups for comparison.
Sit the elf next to the cups holding a ruler.
In the morning, compare: the plain-water bear swells big and soft, the salty one barely grows, the dry one stays the same.
Ask the kids why. Water moves into the bear; salty water pulls much less in.

Tip: Don't eat the soaked bears. Gummies are a choking risk for kids under 4.
