WikiTest is a modern book test that uses a borrowed smartphone. “Marc's apps are unbelievable.” —David Blaine “The greatest app for magicians. It's incredible.” —Asi Wind - You ask a spectator to search for ANY object, person or place on Wikipedia on THEIR phone to bring up its article. - Whilst you look away, the spectator scrolls through the article and thinks of a random word on the page. - You then tell the spectator EXACTLY what object they're looking at, as well as what word they're merely thinking of on the page! The text (and of course their phone) can be thoroughly inspected after the routine with NOTHING to find! * Works with ANY borrowed modern smartphone, tablet or computer. * You NEVER touch their phone! * VERY easy to perform. * NO accomplice required. * NO memory work needed. * Works in English, French, German, Spanish, Dutch, Italian, Swedish, Brazilian Portuguese, Norwegian, Danish, Japanese, and Bahasa Indonesian with more languages added regularly.
