Mr. Myers is asking people to bring him consecrated hosts from Mass: the Body of Christ. It’s interesting that he seems to believe there’s a difference from unconsecrated hosts (which anyone can order off the Internet). However, he has know way of knowing by sight whether they’re consecrated or not. They’re just little circles made from wheat and water, not even what I’d call a cracker. I make crackers from nutritious ingredients, with some substance so that they’ll hold cheese or taboulet.
This reminds me of the time Jesus met the possessed man, and the demon said, “I know who you are - the Holy One of God!”
I believe the professor made clear he was trying to obtain a transubstantiated host. Wafers: not so tought to get.

1376 The Council of Trent summarizes the Catholic faith by declaring: "Because Christ our Redeemer said that it was truly his body that he was offering under the species of bread, it has always been the conviction of the Church of God, and this holy Council now declares again, that by the consecration of the bread and wine there takes place a change of the whole substance of the bread into the substance of the body of Christ our Lord and of the whole substance of the wine into the substance of his blood. This change the holy Catholic Church has fittingly and properly called transubstantiation."204
1377 The Eucharistic presence of Christ begins at the moment of the consecration and endures as long as the Eucharistic species subsist. Christ is present whole and entire in each of the species and whole and entire in each of their parts, in such a way that the breaking of the bread does not divide Christ.205
1413 By the consecration the transubstantiation of the bread and wine into the Body and Blood of Christ is brought about. Under the consecrated species of bread and wine Christ himself, living and glorious, is present in a true, real, and substantial manner: his Body and his Blood, with his soul and his divinity (cf. Council of Trent: DS 1640; 1651).
