This is a borrowed phone effect, and for that reason - most modern day audiences think you're really
doing some big time magic in manipulating their phone. (You just need to make sure their phone has a
flash)
It plays well with kids and adults - and the what I injected into the trick was I
pretended that I just needed to take a picture of the cloth to activate the ghosts inside and then
predicted their card - which they worked hard to shuffle back into the deck.
After they
were wowed by the prediction - I handed the phone back, but with it still turned on to the person
who loaned it to me. Just as people were asking how I did the trick, the phone loaner went nuts
about the picture they saw. I looked confused, "So, I guess you didn't believe me when I said I had
help from ghosts?" And then everyone scrambled to get a look at the phone.
It was a very a
fun, simple trick - a beginner can do it. Plays great with kids - but fools adults as well.
