About this experiment

Drag left/right on the beaker to tilt it. Particles respond to gravity and bounce off the beaker walls. Raise the temperature to see Brownian motion speed up. Different substances have different densities — oil floats above water, and acid sinks below.

Kinetic Energy: KE = ½ mv² ∝ Temperature
