A team of mathematicians has devised the most precise recipe yet for blowing perfect bubbles, and it’s not just for fun and frolics. Achieving a better understanding of the dynamics at work could lead to more efficient industrial production of commercial sprays and foams, like shaving cream or Reddi-Wip—pretty much anything that has drops or bubbles in it.

Bubbles have long been serious science. Back in the 1800s, Belgian physicist Joseph Plateau outlined four basic laws of surface tension that determine the structure of soapy films. Surface tension is why bubbles are round; that shape has the least surface area for a given volume, so it requires the least energy to maintain. (As gravity pulls the liquid downward in a process known as coarsening, the shape starts to look more like a soccer ball rather than a perfect…
