Look at the spiral for 20 seconds
Look at the spiral for 20 seconds is a screamer video uploaded to YouTube on August 14, 2012 by BlueRoseHilbert.
The title of the video tells the viewer to stare at the spiral for 20 seconds. The description also tells the viewer to turn up the volume for surprise. After 20 seconds is over, a picture of a person with no eyes and a wide, open mouth appears with a scream from K-fee commercials, before showing a text that reads: "Scared???". The image used in the jumpscare is a screenshot from one of Dane Boe's videos.
