Self-siphoning beads : ウィキペディア英語版 | Self-siphoning beads
The self-siphoning beads or chain fountain phenomenon is a counterintuitive physical phenomenon observed when one end of a chain of beads held in a jar is thrown over the edge of the jar, and is then followed by a self-sustaining stream of beads, rising from the body of the chain in the jar, up into an arch ascending into the air over the edge of the jar, and down into the outside world, as if being sucked out of the jar by an invisible siphon. The phenomenon was first brought to widespread public attention in a video made by the TV presenter and science blogger Steve Mould. A variety of explanations have been put forward as to how the phenomenon can best be explained in terms of basic physics concepts such as energy and momentum.〔〔 〕 ==See also==
