Answer 1

CHROMATOGRAPHY FLOWERS

• Chromatography is the process of separating a solution into different parts — like the pigments in the ink used in markers. If you draw stripes around a coffee filter, then fold it up and dip the tip in water, the water will travel up the filter and separate the marker ink into its different pigments (in cool patterns that you can display as a craft project). This family made the end-result even brighter by adding an LED circuit to the center.

MAGIC MILK

• Put a few drops of food coloring in a shallow bowl of milk, and they'll stay that way — as self-contained blobs. But add a little dish soap to a toothpick or a Q-tip and touch the food coloring, and the colors will swirl around on their own like magic. It all has to do with surface tension: At first, the food coloring stays on the surface, but the soap causes a chemical reaction that breaks the surface tension.

WATER WALKING

• You'll need six containers of water for this one: three with clear water, one with red food coloring, one with blue coloring, and one with yellow coloring. Arrange them in a circle, alternating colored and clear containers, and make bridges between the containers with folded paper towels. Your kids will be amazed to see the colored water "walk" over the bridges and into the clear containers, mixing colors, and giving them a first-hand look at the magic of capillarity.
