Exponential water tank

Demonstration, Visualization

This example aims to demonstrate our inability to fully grasp exponential functions.

Our action hero stands on a platform inside an empty 4000 litre water tank. At the very bottom of the tank lies a magic drop of water. Invisible to the eye now, it doubles in size every 10 seconds.

Although the growth rate is constant, for a long time we see no change. But there's a well known limit, the capacity of the tank. Once he realises that water is rising exponentially, poor pixellated Chris has no time left to react.
