MrBeast attempts to spend seven days in solitary confinement in a soundproof white room with zero human contact or stimulation. A doctor monitors his psychological well-being, noting the potential for permanent psychological damage after extended periods in such an environment. Throughout the challenge, MrBeast experiences significant boredom, difficulty sleeping, a distorted sense of time, paranoia, anxiety, and depression as he struggles to keep himself entertained and cope with the extreme isolation. He invents various ways to pass the time, including counting tiles, counting rice grains, and creating imaginary scenarios. By the end of the challenge, he is emotionally and mentally exhausted but successfully completes the seven days.
