Breaking a bottle with your bare hands isn’t a remotely good idea. Even if you have experience breaking bottles with a punch, you could seriously hurt yourself, and even permanently damage your hand. However, it turns out there’s a way you can pretty safely break a bottle with your bare hands, by hitting it a certain way. The reason it happens is because of science, not because you have magical powers.
As it turns out, it just takes the right amount of liquid in the bottle and just the right palm strike to the bottle’s lip. It’s a pretty cool trick.
