Most of us know how swings work, and experienced it at least once in our lives. Typically, between two two three metres tall, these were always fun, but never scary. Now, imagine a regular swing pulled up to a height of 30 metres, you go to the top, and then, let yourself free fall, until the ropes swing you around in the air. Sounds scary? Right? Words didn't scare me until I signed up for a test drive of the Swoop Swing.
