Although the plexiglass pods in WWE’s Elimination Chamber structure has long been billed as “bulletproof” and “unbreakable,” an unusually high breakage rate has led the company to seek stronger options, such as plastic food wrap.

Since the inception of the so-called “Devil’s Playground” in 2002, the Elimination Chamber has produced countless exciting moments, and “a roughly 98-percent shatter rate among the seclusion pods,” according to a recent study of the chamber’s structural integrity.

Paradoxically, the pods are very effective at keeping wrestlers locked in until their turn to enter the match, but then become highly brittle once the match has reached a certain level of tumult.

Among those who have smashed through the pods:

Wade Barrett

Mark Henry

Chris Jericho

Dolph Ziggler

Umaga

Hornswoggle

A syrofoam cup thrown by a fan

A light breeze

According to backstage sources, Saran Wrap is a leading contender to replace the plexiglass, other options under consideration include balsa wood sticks, tissue paper, and the honor system.
