It is not a suggestion, it's the new and shocking effect created by the sick mind of Dan Alex #Liar.
A surprising effect with any borrowed spectator phone!
The magician borrows a phone, then scratch the screen with her fingernail,and shows the spectator a little piece of the screen raised! Immediately he passes hand on it and restore it magically.
Easy to do, 100% visual, hands clean at the end of the routine.
Not to be missed in your street repertoire!
Hope you enjoy!
