But there’s a way to make bubbles last much longer, maybe even for hours. Researchers from the University of Lyon in France found that if they trapped a bubble between two platinum electrodes and delivered a charge, the soap flowed upward against gravity. The bubble’s walls became thicker and more stable and even changed colors.
The research gives new insight into the strange world of fluid dynamics and could help improve experiments with lab-on-a-chip technologies.
