Ask the audience to choose a number between 1 and 15 first.
Then, take your smartphone out.
It will display a magic slate with which you can conjure up the number they have just called.
By simply shaking or turning your smartphone over the chosen number will appear at the
center of the slate.
The trick may be played over again instantly.
