We Don’t Know How These Connected Beads Defy Gravity But It Looks Great In Slow Motion
YouTube user Steve Mould discovered that if you take a glass full of connected beads and let them fall from the glass, by some trick of physics they seem to defy gravity by flinging themselves upward into the air before falling. The BBC’s Earth Unplugged brought Mould on to, with the help of slow motion video, attempt to figure out how these beads behave in such a bizarre manner.
“If you’ve got something traveling very quickly, it’s got momentum,” Mould explains. “So you have one side traveling up and it wants to change so it’s traveling down but it can’t do that in an instant, because that would require infinite force.”
