Fluids at rest

4B: Fluids can be fun even when they’re not moving. A still pond has more going on with it than meets the eye - why exactly do you even float when you decide to jump in on a scalding summer day? It’s because you displace a volume of water that provides a buoyant force upward, counteracting the downward pull of gravity. You will find out why the great Archimedes ran through the streets of Syracuse shouting "eureka" millennia ago in Ancient Greece as we also delve into the concepts of pressure, specific gravity, buoyancy, and Bernoulli's principle.
