Britain's Got Talent audience members were left gasping for air during a heart-pounding escape act.
In an unseen clip from the series, Li Lau, 38, and Brendon, 27, enter the stage to perform their act, which sees Lie chained to a chair while Brendon attempts to solve several Rubik's Cubes.
And all this had to be a done with a crossbow pointing directly at Li's head. No pressure, then.
If things weren't tense enough, the hit show also revealed that things hadn't quite gone to plan in the past for the pair.
In the clip's caption that was shared on social media, it says: "The last time Li Lau and Brendon attempted this act, it almost ended in disaster! Can Li Lau escape from the chains, and will Brendon be able to stop the dart by solving Rubik's Cubes?! Watch if you dare..."
After having Ant and Dec enter the stage to help mix up the Rubik's Cubes, Li and Brendon get to work, with Li chained in position, unable to move.
The basic premise of the act is for Li to escape from the chains while Brendon completes a series of Rubik's Cubes - adding them to the scale to buy Li time before the crossbow is set off.
As the water begins to trickle out of the bottle, Simon Cowell and the rest of the judges become increasingly tense, with audience members covering their eyes - even Ant and Dec can't watch.
Brendon makes it through two of the cubes but seems to struggle with the third, the scales getting worryingly close to pulling the crossbow's trigger as he does.
With timing running out, Li appears to be having some difficulty with his chains, and an understandably panicked expressed sweeps across his face.
But somehow, at the very last second, he manages to remove the lock from around his neck and dodge out of the way of the crossbow's bolt.
After that heart-stopping act, I think we could all do with something a little bit more light-hearted. And another BGT contestant has just the thing.
Mr Uekusa, 32, from Japan's Saitama Prefecture, has been entertaining his 700,000 social media followers during lockdown, occasionally performing the NSFW trick which he had hoped to show the Queen at the Royal Variety. Imagine.
In his latest video, he decided to give a shout out to frontline workers. In the clip, he can be seen lying on the floor while covering his nude body with nothing but his famous red tablecloth, and only teacups and saucers to cover his nipples and private parts - as you do.
A handwritten message which says: "HEALTHCARE WORKERS" appears on his stomach as he rips away the tablecloth with speed and accuracy, revealing another note reading: "THANK YOU!"
