To avoid the teapot effect, the pot can be filled less, so that a larger tilting angle is necessary from the start. However, the effect or the ideal filling level again depends on the can geometry. The teapot effect does not occur with bottles because the slender neck of the bottle always points upwards when pouring; the current would therefore ...
Operation Teapot was a series of 14 nuclear test explosions conducted at the Nevada Test Site in the first half of 1955. It was preceded by Operation Castle , and followed by Operation Wigwam . Wigwam was, administratively, a part of Teapot , but it is usually treated as a class of its own.
The stirring makes the water spin in the cup, causing a centrifugal force outwards. Near the bottom however, the water is slowed by friction. Thus the centrifugal force is weaker near the bottom than higher up, leading to a secondary circular (helical) flow that goes outwards at the top, down along the outer edge, inwards along the bottom, bringing the leaves to the center, and then up again.

Rope trick effects visible from one of Operation Tumbler–Snapper's tower-mounted test shots in 1952, taken with a rapatronic camera. The adjacent photograph shows two unusual phenomena: bright spikes projecting from the bottom of the fireball, and the peculiar mottling of the expanding fireball surface.
The Seven Teacups trail in the Sierra Nevada, in which three friends tragically lost their lives trying to save one another, had "significant flowing water" and other potential challenges for hikers.
McGrain v. Daugherty, 273 U.S. 135 (1927), was a case heard before the Supreme Court, decided on January 17, 1927.It was a challenge to Mally Daugherty's contempt conviction and arrest, which happened when he failed to appear before a Senate committee investigating the failure of his brother, Attorney General Harry Daugherty, to investigate the perpetrators of the Teapot Dome Scandal.
The geometry was very similar to that of the tea-pot whistle. After a number of tests at various speeds, orifice diameters, and orifice thicknesses, they concluded that the whistle was created by a Helmholtz resonance in the cylinder volume. There was enough data for one case in their study to calculate the Strouhal and Reynolds numbers.
