Blood Bath

Summary
Mark and Ethan brew and lie in a bath filled with fake blood that's made out of Maizena corn starch, Karo dark and light corn syrups, Kroger chocolate syrup and assorted food colors, Folgers classic roast instant coffee, Grandma's Molasses, Betty Crocker gel food color, cherry and chocolate Jell-O and ketchup.

Fake-out endings

 * Ethan makes the Unus Annus spiral in the bathtub using syrup and starts chanting the video's intro, as the channel's clock overlaps across the screen before glitching out. This causes Windows' blue screen of death to pop up with its error message featuring a sarcastic jab at Microsoft's system maintenance. The video resumes a few moments later.

Trivia

 * The opening and ending scenes feature animated sequences by UltraMarine.
 * The intro sees Mark and Ethan walking up to the screen in tandem with its Unus Annus chant, as they break the fourth wall by pulling down a black cover over the title sequence.
 * The outro sees Mark and Ethan's Unus Annus silhouettes swinging a pendulum-like timer towards one another. As Mark catches it, the clock turns into a skull, followed by a rose with its petals blowing in the wind. As one lands on a body of water, it transforms again into Ethan leaning against a scythe. The final transformation has the scythe bearer turn into the Unus Annus hourglass, as the scene zooms out to show the device lying in the hands of Mark's silhouette, concluding the video.
