Actual, turning the bread and wine into realio-trulio flesh and blood is not transubstantiation. According to Catholic dogma, it isn't the physicality of the products, but the substance of them, the underlying reality, that is the miracle. In fact, the church has gone so far as to claim that after the transformation into the body and blood of Christ, the bread and wine are, to all sense and to any scientific test imaginable, unchanged in physical form.
So, the way to prove transubstantiation would be to get some bread and wine, pray over it, and lo! watch it magically transform into...bread and wine.
