Science News : A stone hitting a pond can produce a tiny supersonic splash, a new study has found.Researchers studying the shape of an air cavity made when an object hits a liquid noticed a similarity to the shape of the nozzles that are in supersonic jet engines. Sure enough, air escaping from the cavity can reach supersonic speeds, the team reports in a paper published online 11 January in Physical Review Letters.
