Homework question - Philippe Petit's knees Answered
#2 Son is doing a short talk at school on Philippe Petit, the Frenchman that tightrope-walked between the Twin Towers.
He has plenty of information, except he has found several references to a move Petit did called "knee salutes". He would like to do one in front of the class, but we can't find an image or description of the move.
