While soap bubbles are known for their fragile constitutions, the new bubbles can stick around for more than a year before they pop, scientists report January 18 in Physical Review Fluids.
Instead 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 can easily rupture (SN: 1/12/17). Evaporation of the liquid film
