Incredible mind-reading using Snapchat that will also help you gain tons of followers!
The magician has a spectator add them on Snapchat and then ask the spectator to send them a message. The magician shows that the message is received but doesn't open it, the magician takes a snapchat photo of the spectator, writes a prediction on it, and sends it to the spectator.
Both the spectator and magician have unread messages. Both messages are opened side by side to show they match.
This can also be performed using a spectators phone as well if you want to approach a group of strangers and you don't want them to have your Snapchat or if you don't have a Snapchat.
Incredible mind reading that is easy to perform with their phone or your own!
