Science & Discovery

Raisins bob up and down in a clear cup of fizzy water while the elf watches with a magnifying glass. How do they dance?

The elf left baking soda snowballs in a muffin tin and cups of colored vinegar. Every drop makes the snow fizz and bubble in a new color.

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.

The elf froze a herd of tiny animals in a block of ice. The kids' mission: rescue them with droppers of warm water and a pinch of salt.

A plate of milk with dots of food coloring waits by the elf, plus a cotton swab with a dab of soap. Touch it and the colors explode.

The elf made a lava lamp in a clear cup: colored water on the bottom, oil on top, and a pinch of salt that sends blobs up and down.

Tiny tissue paper snowflakes are scattered on the table, and the elf is holding a balloon that pulls them up like magic.

The elf started an experiment before bed and it worked while everyone slept. Colored water climbed paper towel bridges between cups and filled the empty ones with a rainbow.
