Football with a bull

In Nevada, people play a form of football with a bull. Daredevils run into the arena in transparent spheres and become "balls" for the bull.

Participants, half-hidden in protective bubbles, run into the arena, where a fierce opponent awaits them.

The bull attacks the rolling balls, butting them with its horns and throwing them up with its hooves. People tumble, fly off, and try to escape again, which only excites the animal. Despite the danger, spectators and participants themselves clearly enjoy this unusual competition.
