A Spanish filmmaker boarded a train in Sri Lanka with a dangerous idea in mind – climb to the roof while the train was running. Arnau was visiting the country in December 2015 with two friends to record some interviews for a documentary. The video atop a moving train was not planned, but was dreamt up as a way to pass the time on a nine-hour journey. Arnau managed to avoid police detection and serious injury, but don’t try this at home! Credit: YouTube/Arnau Mateu
