It definitely resonates with younger audience members but most certainly confounds older ones as
well.
It's easy as can be to perform and you can personalize it really well for any crowd.
The trick has a seriously good shelf life as well.
Truly the only thing you need
to make sure of before you perform it is that someone in the crowd has the Instagram app on their
phone. If they don't I guess you have to give them your phone to take a look - but then it looks
like you did something silly on your phone, when the point of the trick is that you did not.
This is not in any way a complaint - just letting you know that for the trick to have the proper
effect someone needs to have instagram on their phone in the crowd.
