Wally Wallington, a retired carpenter, has been exploring ways of using primitive tools and the laws of Physics to lift incredibly heavy items like five-ton blocks of concrete (that's 10,000 pounds) all by himself and without any effort. He does not use any wheels, rollers, pulleys, or any type of hoisting equipment. He has simply mastered the astonishing power of the lever.
you view his videos, you are forced to conclude that Wally has solved the mysteries
If ever there was a guy who accomplishes more through harnessing the enormous power of “doing less,” Wally Wallington is the man.
