Is Communion in the hand a sacrilege?

What happens when a father and son experiment with the distribution of unconsecrated communion hosts in the hand? What if they tell the pope the results?

An ex-Eucharistic Minister made a scientific study of what occurs when a communicant receives Holy Communion in the hand.

How many Sacred Fragments are caused and dropped—even when the Host is given as reverently as possible?

Includes the letter to Pope John Paul II detailing the study's results and the Vatican's response.
