When we were kids, just about all of us probably used a swing-set at some point. They are at found in most public parks and are a pretty ubiquitous part of everyone’s childhood. However, in Estonia, swinging is much more than just something children do to pass the time. As children, we probably all tried to swing over the bars at some point, and found it was pretty much impossible, due to the design of our swing-sets.
We would compromise by simply getting really high and then seeing how far we could leap out. The Estonians, however, were not to be deterred from flipping all the way over their swings. Being a huge fan of swing-sets, one Estonian invented a new sport that has become quite popular. Essentially, he built a better frame, designed solely for the purpose of going all the way over the bars—and doing so is basically the entire point of the sport. It is extreme, insane, and incredibly cool.
