A closer look

Estonia officially invented the extreme sport of kiiking, which translates to swinging, where athletes strap themselves to massive steel swings and try to rotate a full three hundred and sixty degrees over the top spindle. The longer the swing's arms get, the harder it is to complete a full loop, making it a brutal test of lower body strength and pure, unadulterated momentum. Unlike typical tourist traps, this activity requires you to essentially function as a human pendulum while fighting off intense nausea and the very real terror of structural failure. Why anyone thought playground equipment needed to be optimized for maximum centrifugal dread is beyond comprehension, but it does make a standard sightseeing bus tour look profoundly pathetic
