BRITAIN'S Got Talent viewers' hearts are sure to stop when an underwater act puts his life in the judges' hands on tonight's show.
Escape artist Christian Wedoy is hoping to make a real splash on the BGT stage with his terrifying act, which sees him locked in tank filled with water.
Submerged in water and holding his breath, Christian tries to unlocked four different padlocks; his hands, waist and neck with the help of David Walliams.
After David placed the keys into the case, Christian is seen struggling to open the locks and to hold his breath. The judges at this point are beyond worried as his friend explains to the audience "if he goes over four minutes, we're in a very bad place".
