Every Saturday, the South China Morning Post will be presenting its top video picks from SCMP.tv and the web - featuring news, features, mini-documentaries and more. This week...from parkour-loving Afghan youngsters to a Canadian man taking flight in a lawn chair, here are our top five videos of the week. Canadian Man flies balloon-powered chair over Calgary Stampede Aircraft seats can be so uncomfortable. This Canadian man decided he was going to travel in comfort by flying in his own lawn chair. Using dozens of helium-filled balloons tied to the seat, he flew himself over the city of Calgary to cloud-level height.

He was soon arrested and charged with mischief causing danger to life.

But, like most people would, he failed at his mission - consuming only a mere 4,300 calories. Excuse us, as we pull out our barf bags... Korean girl re-enacts Jurassic World Trailer in her apartment If you still haven't watched Jurassic World yet, let this side by side reenactment be your incentive to get off that computer, gather some friends and head to the theatre. We personally think this girl has a little too much time on her hands, but we won't hold it against her. With her hairclip teeth and claws made of beans, we think she comes pretty close to the real thing. Click here to see the original video.
