This experiment demonstrates capillary action - how water can climb up through tiny spaces in materials. You'll create a beautiful rainbow pattern while learning about the same process that helps ...

GRAND RAPIDS — Have you ever wondered if water can defy gravity? In today's experiment we are actually going to make water walk through a rainbow of colors while defying gravity. So here is what you ...

GOBLES, Mich. — Seeing a rainbow in the sky is always a stunning sight! But, have you ever tried to grow your own rainbow at home? In this week's weather kids experiment, Haleigh Vaughn creates a ...

When you water plants, you water their roots. But how does the water travel all the way from the roots of the plant to the leaves? They are standing upright: wouldn’t that defy gravity? In fact, there ...

Introduction How do trees suck water all the way up to their leaves? How do paper towels soak up a spill? Are these things related? Try this project to learn about capillary action, and repeat a ...

Place cups in a row (I used five cups). Fill the first, third and fifth cups most of the way full. Add food coloring to the water. To make a rainbow effect, add a few drops of blue color to the first ...

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, and in opposition to, external forces like gravity. In this walking water experiment, liquid uses the ...

Today's Challenger Learning Center science experiment involves the colors of the rainbow. Kristin Hibbard was in our studio to show us the science behind capillary action. Line up three empty glasses ...
