Solid materials get all the production credit. Don’t get us wrong, we depend on their strength and firmness for bridges, bones, and bento boxes. But liquids do us a solid, too. Their free-flowing properties drive the Earth’s magnetic field, inspire a new generation of smart electronics, and make biology possible. But the weird thing is, they elude clear definition. Is tar a liquid or a solid? What about peanut butter?

In this episode: A romp through a cascade of liquids with a materials scientist who is both admiring and confounded by their properties; how Earth’s molten iron core is making the magnetic north pole high-tail it to Siberia; blood as your body’s information superhighway; and how a spittlebug can convert 200 times its body weight in urine into a cozy, bubble fortress.
