Hi everyone, In this video, I reveal the magic card trick that fooled Albert Einstein. This is a really powerful magic trick that is easy to do because it is practically self-working. It will give you the ability to guess how many cards are in a pile just by weighing it with your hand! If you have any questions please ask me in the comments section below. Cheers! Note: The original trick was performed with coins, not cards, but effect and prediction are exactly the same.
