That same tension can keep it from breaking and even allow it to bounce off a minuscule layer of air. This clip from “Time Warp” reveals things you never knew about the behavior of water, shot using a high-speed camera at about 1000-10000 fps and color to add to the wonder. The most fascinating examples start at 05:39.
