One of the bubbles, made with water, glycerol and microparticles, lasted 465 days before popping.
While soap bubbles are known for their fragile constitutions, the new bubbles canInstead of soap and water, the bubbles are made with water, microparticles of plastic and a clear, viscous liquid called glycerol. That trio of ingredients staves off factors that normally hasten a bubble’s death.
In a standard soap bubble, gravity pulls liquid to the bottom of the bubble, leaving a thin film on the top that . Evaporation of the liquid film also saps bubbles’ stamina. In the everlasting bubbles, plastic particles cling to the water, maintaining the film’s thickness. Meanwhile, glycerol absorbs moisture from the air, counteracting evaporation.
“When we discovered that the bubble didn’t rupture after days we were really astonished,” says physicist Michael Baudoin of Université de Lille in France. So he and colleagues waited to see how long the bubbles would last. And waited, and waited. One bubble persisted 465 days before it burst, making it the longest-lived bubble ever produced under normal atmospheric conditions. That bubble turned slightly green before its demise, a potential hint at what caused it to finally pop.
