Demian Aditya's Week 2 Quarterfinals performance in Episode 1213 consisted of performing his "Death Drop" act. Suspended high above the stage, Demian climbed into a wooden box. He was handcuffed, and the lid of the box was nailed completely shut by his assistants. The only support keeping the box in the air was a rope. The rope was looped through pulleys and secured directly above a blowtorch. Demian attempted to escape before the rope burned through and the locks came crashing down onto three solid steel spikes lit on fire. Unfortunately, technical issues arose during the performance: the box failed to fall into the spikes when the rope was burnt through. Nevertheless, Demian appeared behind the judges with a fire extinguisher in hand. Mel B and Simon Cowell buzzed the act. Demian did not receive enough votes to advance to the Semifinals in Episode 1214, eliminating him from the competition instead of Johnny Manuel.
