The Jerx App is a utility magic app that can be used to create a myriad of different effects, including: - A Cute Memory Loss: Cause a spectator to forget something she just saw. - Pee Hill Pot: Induce a mild, momentary loss of cognitive ability. Just by touching your spectator's head you reduce their reading ability to that of a 6-year-old. - ScribBold: You read a spectator's mind, or one spectator reads another's mind to determine a thought of word or concept that is never written down or spoken aloud. - Chocolate/Vanilla Twist: A perfect 50/50 prediction. - Digital Linger: Create dual-reality effects for one person. - I Know What You Need: Apparently implant a thought in a spectator's mind (requires The Jerx, Volume One book).
