A team of world champion acrobatic basketball dunkers put on quite a heart-stopping show on top of a moving train.
The group calls themselves the Dunking Devils and they perform incredible stunts all over the world.
In this clip, several members perform extreme acrobatic basketball slam dunks on a moving train 100 feet above a river. According to the Dunking Devils YouTube page, the performance was in honor of the 110th birthday of the Bohinj Railway in Slovenia — where the Dunking Devils originated.
The tricks involve flames, trampolines, crazy flips and jumping over teammates in various creative (and dangerous-looking) ways.
Be blown away by their stunts in the full In The Know video above.
