WATCH: Eek! ‘Britain’s Got Talent’: Escape Artist Stunt Goes Terrifyingly Wrong

Don't try this at home, folks...

'Britain's Got Talent' semi-finalist Matt Johnson was forced to gesture for help during Monday night's show, after failing to remove a box filled with water from his head.

In a bid to bag a place in the final, the escape artist performed a stunt that saw him pick various padlocks in order to unlock the box, as a two-minute timer counted down behind him.

However things didn't go exactly to plan and as time went on, he was clearly beginning to struggle.
