This trap uses bands that can shrink: a band around the waist, and bands around the biceps and thighs. The prisoner faces a series of painful trials. Failing a trial makes the waist band shrink, while passing a trial makes the limb bands shrink. To escape, the prisoner needs to shrink the limb bands a certain amount (tight enough to force doctors to amputate) and avoid crushing their organs.

The trials involve a button that electrocutes and suffocates the prisoner. The prisoner must hold down the button for some amount of time. Releasing it early fails the trial. This happens over and over again until the victim is released or dies.
