Borrow a spectators phone, then hand them your phone to film the magic… In an instant, their phone vanishes into thin air. No sleeves. No pulls. GONE.
When they ask where their phone is, you point to their own hands. The phone they’ve been holding the entire time is THIER phone.
That means they filmed their phone vanishing, on their own phone. It’s only confusing because the laws of science shouldn’t allow it to be possible.
Their phone exists in two different places… At the same time.
