Jump rope machine

E has become a fast jump roper.  They have contests now at dry land to see who can jump the longest, and he has won more than once.  Here is a video of my little man jumping.  He got 108 jumps this time.  Craziness!  I wasn't sure he would ever get this jump rope thing.  I actually made him this video to show him how much faster he was going than the girls who were left in this round of the competition.  The owner's wife coaches dry land sometimes, and she will not let anyone "skippy doodle" as she calls it.  She wants one jump per rotation.
