For generations, the summer heat has sent kids running through the spiralling streams of water cast from old-fashioned, s-shaped garden sprinklers.
Born out of a thought experiment, this machine functions like an inside-out rocket.
New experiments answer one of the oldest and most difficult problems in the physics of fluids, researchers report.
<p>For decades scientists have been trying to solve Feynman’s Sprinkler Problem: How does a sprinkler running in reverse work? Through a series of experiments, a team of mathematicians has figured out how flowing fluids exert forces and move structures, thereby revealing the answer to this long-standing mystery.</p> <p> </p>
