Get ready to make water walk! In this super cool science experiment, you’ll use clear cups, paper towels, water, and food coloring to create a colorful, moving water loop. You'll watch bright water climb up and over paper towels all on its own to mix awesome new colors! If you're in the younger group, you'll play with color mixing and watch the magic happen. If you're in the older group, you'll uncover the secret science of how water creeps upward—which is the exact same trick giant trees use to drink water straight from the ground!
