You introduce a four digit combination lock attached to a ring. Next, you ask the assistance from a few volunteers to enter a few number combinations to see if they can unlock and free the ring. After a few failed attempts, you instruct one of the volunteers to open the calculator app on their phone.
Next, you have two individuals add their personal info (age/year) into their calculator and try opening the lock, which amazingly it does.
You never touch their phone, nor do you know any numbers entered, uses any four digit combination lock, one time set up that takes seconds. Video performance included.
