Mark Lemon's 'Argon' is a digital magic trick that uses borrowed phones to perform amazing calculator feats. With '10K Odyssey', you can force a total on every calculator in the room, and 'Atomic Code' reveals a spectator's random number without any handling. It works on both iOS and Android, doesn't require you to own an iPhone, and includes extra routines like 'Sum Duo'. The trick comes with a printed booklet and over 2 hours of video tutorials, making it easy to learn and perform.
