Abstract
A flexible state-of-the-art plastic bottle fitted with a sealed tube becomes a dynamic system for dispensing water or other fluid in nearly-uniform quantum amounts, in such a way that the apparatus may be used as (1) a timer, such as for cooking a three-minute egg; (2) a toy for enjoyment or learning how to count, etc.; or (3) a model for teaching differential equations or physics. The device is very simple, on the order of a paper clip.
