The sorcerees at Magic School are facing their penultimate magical subject - illusions, and this time they have to learn two tricks, not one. Miss Evans teaches her class how to transform one person into another, and a stretching arm illusion, whilst Mr Knight shows his pupils how to make a person appear in an empty box, and an arm-twisting trick. The sorcerees are split into mixed pairs for this challenge. Ben is unhappy at being paired with ambitious Amber again - after partnering her in the hip hop clown-off, he steels himself for her bossiness. But having found himself in the bottom three last time, he would do well to heed her advice. Illusions are the biggest form of magic, and the sorcerees will need to demonstrate impressive showmanship to master these tricks. To bring out their inner showman they are set a rock and roll dance challenge, as performed by world champions, the Mini Mezzos.
