Rubber Duck
The rubber duck's velocity profile presents a study in serene stationarity. Maximum recorded speeds occur during bathtub drain vortices, reaching perhaps 0.5 metres per second before the inevitable plughole collision. In open water, drift speeds depend entirely upon prevailing currents and wind conditions—the Pacific cargo spill ducks averaged approximately 1.9 kilometres per day. The rubber duck makes no claim to speed; indeed, its very purpose celebrates the absence of urgency. Velocity is antithetical to its philosophical mission of bath-time tranquillity.
Rocket
The rocket exists as humanity's ultimate expression of velocity worship. Escape velocity from Earth requires speeds exceeding 40,000 kilometres per hour. The Saturn V achieved 39,897 km/h; modern vehicles like the New Shepard reach similar velocities within minutes of ignition. Voyager 1, launched in 1977, currently travels at 61,000 km/h and will do so for millions of years. In the competition for raw speed, the rocket occupies a category so vastly superior that comparison feels almost cosmically unfair to the floating yellow anatid.
