Yes, in the show posted by the OP, there was a little confusion in that he (the Feynman character) went to the hardware store before the demonstration but he went to buy a C-clamp, not an o-ring. IIRC (having seen the show only once), I believe William Hurt, who played Feynman, spoke the actual words Feynman says in the video clip during the dramatization of the o-ring material including the fact that he was using actual o-ring material from the space program. All this is minor detail to an otherwise very well done and fairly accurate drama of real history.
