Physicists Have Argued Over This Problem Since 1883. It May Now Be Solved.

Physicists have debated which way a submerged sprinkler sucking in water would spin. Careful experiments provide an answer.

Solution to Feynman’s reverse sprinkler puzzle also applies to “silly sprinklers”

Researchers at New York University’s Courant Institute conducted a series of experiments with different silly sprinkler ...
