[QUOTE="wiseornotyoudecide, post: 1999953, member: 358827"] Bricks are like any other object used for the KARATE demonstrations hit in places where they can brake easy. Though the material is strong when compressed is weak when put into tension so when you hit it at a specific point around the middle while someone compresses the sides the brick will tend to snap in half, as long as it can be kept from moving and absorb the impact in the middle will also work. Same with the boards notice that they are hit along the grain put them on the side and see if you can brake them perpendicular to the grain, I can guarantee you that is impossible unless is at least as long as 32 times its width and its thickness less than a quarter of an inch... Is all physics. Stop wasting your time proving that physics works, by hurting your body, since that is what will happen until you figure out where to hit the objects more effectively. [/QUOTE]
