Experiment with "Quicksand"
What do you think of when you think of quicksand? Most likely, you'll conjure up images of action heros struggling to get out of a slippery pit of sand. The hero usually needs a sidekick to help him out–the quicksand is too sticky and dangerous to just swim away.
Quicksand has a unique texture that makes it particularly tricky to escape. Comprised of sand floating on top of water, it is both a solid and a liquid. People and animals can get trapped in the subtance easily, as it's impossible to stand or swim in. Quicksand is created when water rushes into sand quickly, as in a flood, underground spring, or earthquake, and usually happens near riverbeds.
Your child will learn about the unique liquid and solid properties of quicksand (in a safe way!) in this hands-on experiment.
