9 Screamers all at once

9 Screamers all at once is a screamer video created by YouTube user Jupiter9099 on May 24, 2012.

The video is 9 screamers running simultaneously. These are, from top to bottom, left to right: K-fee car commercial, The Maze, Luna Game 1; SCP-450, Luna Game 3, Proof of Michael Jackson's Ghost; Ghost Caught on Tape, Stickman Screamer, and Luna Game 2. At 36 seconds into the video, the screamers will all go off at the same time; the shorter screamers are delayed and appear at a later time in the video, so as to properly sync with the longer ones.

There is also another version, 9 Screamer reactions all at once uploaded by the same user - as the title implies, the majority of the video is people reacting to screamers.

The original video has accumulated over 450,000 views.
