Is this the most DANGEROUS escape act to appear on Britain’s Got Talent?

The Britain’s Got Talent judges were left shocked by a super dangerous escape act at this year’s auditions.

In an unseen audition shared online, duo Li Lau & Brendon appeared before the panel of Simon Cowell, Alesha Dixon, Amanda Holden and David Walliams.

They told how they had created a “very dangerous and unique escape act that combines skills of escapology with mentalism.”

Li Lau was restrained to a chair using chains, padlocks and handcuffs – with Ant and Dec securing the locks – while a crossbow was aimed at his head.

Connected to the trigger of the crossbow was a scale which when tipped would fire the crossbow.

For the act, Li Lau attempted to escape from the chains while Brendon tried to stop the dart firing by solving Rubik’s Cubes which he used to weigh down the scale.

Brendon’s Rubik’s Cubes skills helped save Li as he escaped from the chains just before the scale tipped and the crossbow bolt fired.

You can watch the full audition in the video above.
