It was kinda cool actually, but i can totally see people getting hurt making it. I'm pretty sure it was thousands and not hundreds

Last week, the fans of Section S in Canad Inns Stadium created what is known as a beer snake — hundreds or maybe even thousands of empty beer cups stacked together to form a line that covered nearly the entire section, reaching into the upper level.
The injuries were suffered when the beer snake fell apart near the end of the game, showering many of the fans not involved. Fans also threw beer cups, hitting some fans and spilling their contents on others.
