Controlling the Bounce of a Bottle
- amelius 3y agoThe water in the bottle bounces instead so it doesn't work with empty or full bottles. Curious about any applications.
- jareklupinski 3y agohalf-filled fuel tanks bouncing around in turbulence mid-flight accounting for their forces means a smoother ride for the passengers, and lower stresses on the connecting hardware
- raattgift 3y agotl;dr, "A central jet emerges nourished by the incoming water from the walls ... an effective force is exerted downward on the bottom ... the bounce after the impact depends dramatically on how much water is available to descend and hence ... on the initial rotational frequency", from the PRL letter: https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.130.244001 https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.13...
