Real Tempered Glass Was Used in the Glass Stepping Stones Game
In the glass stepping stones game, which was the second to last game in the series, the contestants were forced to step onto tempered glass panels on a narrow bridge. The challenge was to step on the glass that wouldn’t break. Many players fell to their doom, and audiences were on edge the entire time, but they weren’t the only ones.
“Filming Glass Stepping Stones was actually terrifying,” claimed actor Jung Ho-yeon. The show’s director wanted the actors to feel actual fear which is why the show used real tempered glass.
