"Now watch and be amazed! As the Great and Powerful Trixie—" the showmare reared up and shuffled her forehooves theatrically in the air. Light trails blurred in the air as her hooves moved and her horn lit up. Another flash of magic, and a pair of wide, long rectangular blades appeared in a poof of smoke and colourful sparks. The crowd inhaled collectively "—swaps the heads of her brave volunteers!" Her horn flared as the blades slowly, ever so slowly, were inserted into invisible slots just below where the griffon and dog’s heads were. Handy winced reflexively as he saw the blades delve into the boxes... noiselessly. The two upper parts of the boxes, where he and the crowd knew the volunteers' heads should be, were actually carried away, lifted on the levitating blades, up into the air and away from the lower portions of the boxes. They were deposited as the blades were lowered back onto the boxes, the red head box on top of the blue and vice versa.
