CBBC have sent four of the UK's hottest magicians back to school to trick and amaze the pupils. This time they're in disguise as they pretend to be supply teachers to teach some surprising magical lessons to the unsuspecting pupils.
The show also teaches children how to do tricks to fool their friends, and presenter Iain Stirling chooses his favourite Wannabe Wizard from footage sent in by the viewers.
Viewers can join in with the Interactive Illusion and members of the public get to see our magicians on the street Up Close and Magical.
Katherine teaches a Year 5 class physics and does the physically impossible by walking right through a mirror sprayed with the mysterious atom spray. Meanwhile, Fergus uses elec-trickery in class to illuminate a light bulb. Also, the Interactive Illusion involves concentration and a bit of mental arithmetic.
