Top 5 videos of the week: from speed devil's skateboard stunt to the mysterious fireball over Bangkok's sky

This week, we highlight a mysterious fireball that lights up the Bangkok sky (any guesses what it is?) and a skateboarder defying death by racing down a highway at a hair-whipping 112 kilometres per hour. 

Talk about the need for speed. In this video, Zak Maytum, a 24-year-old longboarder, zips down a Colorado road at 112 km/h (70 miles per hour) seemingly without any padding or support, as cars occasionally whip past him. 

In some sections of the road, Maytum crouches lower and uses his gloved hands to touch the pavement, setting off sparks, and doing little twists on his skateboard.
