Before the Raiders' new stadium in Las Vegas can open this year, it's going to have pass a bunch of important tests, and one those key tests came on Wednesday when the stadium made it through its "Super Flush" test. If you're wondering what goes into that test, it's the one where the workers at the stadium go into all 297 restrooms at the venue so that they can flush all 1,430 toilets and urinals at the same time. Oh, and while that's happening, the workers are also making sure that every sink in each restroom is running. The test is done to make sure the stadium's plumbing system can handle a game day crowd of 70,000 fans.
