I was always in awe of tightrope walkers as a kid.
High above the crowds and the safety of the ground, these professionals would perform dazzling stunts in front of hundreds, sometimes thousands of people on a wire the width of a quarter. From quick turns, to flips, to even laying down on the wire, these performers were and always have been amazing.
How does one get good at walking a tightrope though? Surely lots of practice goes into it, but all (sane) tightrope practitioners use a harness to stay attached to the wire or a safety net to catch from below if things go wrong.
