It is also known that other body parts may be transported via Floo Powder, as Umbridge almost catches Sirius the second time he converses with Harry through the Floo network.

It is therefore against British wizarding law to charm carpets or fly them, although they are still legal in other countries. Mr. Weasley was heavily involved in the introduction of this legislation due to his position in the Misuse of
