You may also know this illusion as the TOPSY TURVEY, but under any name, it's one of the most devilishly creative props ever devised. Your assistant is placed within a tall, thin box, just big enough to hold her. The box is pivoted
on a central post so that she is in an upside down position....YET SHE CONTINUALLY STAYS UPRIGHT! Our plans feature a unique modification which allows you to actually show her in the reversed position just before the switch.
