Episode 9: NASA high jinks with Dr. Paddack

Dr Paddack, one of the discoverers of the  YORP effect , tells some funny stories from his time at NASA. Here he shows an element from his famous experiment; a simplified spacecraft model with uniform color. When placed in a vacuum attached to a friction-less bearing, this element started spinning when a light was shone on it.
