Graveyard Carz (2012)

S1E11 Oasis

In an astonishing and daring challenge, Criss plans to live inside a massive, transparent tank filled with water, encased in an air bubble. Without any food and only a small amount of air to breathe, he will endure this for a full 24 hours. As the countdown concludes, he will vanish right before the audience's astonished gaze.
