This is the first in a series of 3 video clips. In this first video, a slinky is held in the air by one end. The question is asked: when the slinky is let go, will the top fall first, will the bottom fall first, will the slinky “accordion” together first, or will the whole slinky fall at the same time? Students are asked to make a prediction. The result is not given in this video, but is instead seen in the second video, “Slinky Drop Answer”, at https://www.youtube.com/watch?v=eCMmmEEyOO0. “Slinky Drop Answer” also posits another question: what if a weight (a tennis ball) is attached to the bottom of the slinky? The result is shown in the third and final video, “Slinky Drop Extended”, https://www.youtube.com/watch?v=oKb2tCtpvNU, which also relates the phenomenon to other applications in sports. (A fourth video, with background for teachers, is available on the Veritasium website, www.veritasium.com).
