Predict any number a spectator is thinking of - and much more. GAUSSUS is a calculator that gives you a superpower. A new tool built especially for mentalists, magicians, and anyone who wants to leave people absolutely amazed. Here are just some of the effects you can perform with GAUSSUS: 1. A spectator thinks of a random number - any number - and you reveal that you had already written it in advance on the calculator on your iPhone. 2. Two spectators (or more) think of different random numbers, and you reveal that you had already written the final total in advance on the calculator. 3. A spectator thinks of the birth date of someone close to them, and you reveal that you knew the date in advance. The possibilities are endless.
