"Engineer James Bird estimates that he watched thousands of bubbles pop while he was getting his Ph.D. at Harvard University. With the help of high-speed cameras, Bird and his colleagues discovered that when interfacial bubbles--bubbles resting on water or a solid--pop, they give birth to a ring of baby bubbles. The discovery, published in Nature, has implications for soda drinkers and global climate estimates."
