Bubbles can be observed “galloping” across the surface of a liquid-filled container through a simple up-and-down shaking motion, revealing a surprising phenomenon that may lead to innovative cleaning methods.
Researchers at the University of North Carolina at Chapel Hill were investigating wave behavior within a sealed container using vibrations when they stumbled upon this unexpected discovery. The team determined that shaking the liquid-filled chamber at specific frequencies induced the bubble motion, opening avenues for potential applications in cleaning technology.
