Soap-bubble cyclone is a deadly storm in miniature

"Led by Hamid Kellay, a group of physicists at the University of Bordeaux, France, heated soap bubbles from underneath to create large vortices like the naturally colourful one pictured. By varying the temperature and rotating the bubbles, they studied how these spinning, storm-like structures develop under different conditions using a camera that shoots up to 500 frames per second.”
