Aside from the ones Jeb Corliss, and other wing-suit fliers, the first (or at least the first I saw) use of a go-pro on a hula hoop was, and still is, my favorite.
It is now over three years old, and there have been many that followed.
Here is an idea. Strap one to a snake. That might go viral.
Tons of them put on dogs, skateboards, bikes, vehicles, and drones.....
Meanwhile, here is the one I first saw on a hula hoop, three years ago.
