A good specific example of this that isn't widely known is the "muscle pass".

It amounts to holding a coin in a classic palm position (dead center of the palm), then spending several months strengthening the palm muscles and developing a callus, until you can propel the coin a foot or so without noticeably moving your hand.

That's also a trick

Edit: but look, it's a good one. A little bit of reality mixed in so it looks cool
