Remember when we were kids playing on the swing set and we'd try to swing so high that we'd fly over the top bar and come down the other side? No, I never made it either. But in Estonia, they've taken a childhood dream and made it an extreme sport.

It's called kiiking. Using a special swing with steel arms instead of chains, the kiiker stands on the swing and pumps back and forth until he or she gets enough momentum to make a full 360-degree turn. The best kiikers can go around several times. The longer the shaft of the swing, the harder it is, and according to the "Guinness Book of World Records," the record for kiiking is with a 7.02-meter (23-foot) swing used by Andrus Aasamäe of Estonia on August 21, 2004.

Kiiking has taken off in the Baltic states and in Scandinavia. Here we show a video of the Estonian army taking a little time off from defending the nation to practice kiiking.
