Float It! Sink It! [Science It Up!]

Oh yeah, this is a good one! We’ve all kinds of fun ways to explore buoyancy. What makes something buoyant, anyway? What factors are involved? Here are some great ways to start thinking about those questions. Bubbles, a fish tank and molding clay are some of the easier-to-aquire items. But who has a liter of mercury just lying around? (Answer: Little Shop of Physics’ Kenn Lonnquist.) So Kenn joins us, Nisse and Doug, to explore buoyancy, and he graciously loans us his liquid metal. What doesn’t float in a quart of quicksilver?!
