The Belgium 'mentalist' stayed silent throughout his audition, which saw show co-host Ant and members of the audience become unfortunate volunteers in a worrying illusion.
Aaron blindfolded himself before carrying out a range of moves on objects held by Ant and two fans from the audience.
Ant, who had a pineapple on top of his head slice off by Aaron, admitted: "I was genuinely terrified as Aaron was coming towards me. It was an incredible act. Everyone was on the edge of their seats.”
His co-host Dec added: “Watching Ant from the wings was pretty nerve-racking. I mean, if anything had gone wrong it would have been the end of our career!”
Now Arron hopes to make it through to the live shows, where he wants Simon Cowell to be part of his next trick, which involves knife throwing.
A BGT insider told the Daily Mirror today: “Aaron’s performance went down a storm with the judges and viewers.
“He’s already started preparing himself for the finals. If he gets through he’s hoping the judges will be part of his act. It’s a first for the show and all the judges are keen to get involved.”
But Simon wanted David Walliams to go first, saying on last night's show: “If you were to make it to the next stage would you be willing to put David on stage, in that situation, with something slightly smaller than a pineapple?”
