The stadium's staircase is constructed in the Cylendric style. Consequently, it appears as though the building is moving when people use these staircases.

Due to the popularity of the illusion's video on social media, this tweet has received over 10,000 likes and has almost 1 million total views.

Interesting comments are being left on the amusing video in the comment area. The viewers of this video on social media also understand why this is happening.

"I have a feeling they meant that the staircase isn't moving at all. If I look at the top and focus more on the people, it doesn't really look like it's moving. Not sure if that's what's happening though," wrote a user.

"I see no staircase; it's a ramp. And the building seems to rotate in the direction people are going, not the opposite direction. But great video," commented another user.
