Origin

Dr. Duncan "Om" MacDougall (1866 - 1920) was an early 20th-century physician who sought to measure the mass lost by human when the soul departed the body at death. Measuring the mass change of six patients at the moment of death. Duncan believed the soul weighed twenty one grams (.04 pounds). The first experiment in 1901 weighed six patients who were dying from tuberculosis in an old age home. Each bed was placed on an industrial sized scale which was sensitive to "two-tenths of an ounce". The results were inconclusive as only one of the six patients in fact lost mass after death. All the hours, belief and money went into finding the answer and in the end he concluded that the soul had weight, the weights he used absorbed his determination.

Effects

Even though the weight only weighs 21 grams when placed on top of something the object gains 21 pounds, weight can then be picked up and set down again gaining another 21 pounds. It can be done indefinitely until the weight is neutralized.
