Kristian is tandem skydiving with his instructor when things take a turn for the worse. Their lines suddenly become twisted mid-air, but don't worry — Kristian's been doing his homework! He's watched dozens of skydiving videos to prepare himself for situations like this, so he knows that the best way to help his instructor untwist the lines is to start kicking his legs. Sure enough, it works like a charm, and the two manage to land safely on the ground. Well done, Kristian!
