Physics behind breaking bricks with bare hand

Smashing bricks with bare hands! How someone's hands weren’t shattered along with the bricks? The interesting physics behind this mind blowing job:


In a word :“It has to do with the impact time. It’s very quick,” At the point of impact, the amount of force one's hand applies to the brick produces an equal reaction force from the brick to his/her hand. Hand is a bit more elastic and can “move up” without breaking. The key is to keep the impact time as short as possible by striking fast and hard while exerting the maximum possible force.

That's it! It's important to takes into account one's confidence level. If he/she hesitate, he/she’ll slow down and increase the likelihood of breaking hand from a failed attempt.

That’s why it takes years of practice and focus to break bricks, and why most people who can start with things like boards of various thicknesses.

Please, don’t try this without supervision unless know what you’re doing.
