Say that a wizard were to foolishly give a Muggle a potion, Time-Turner, broomstick, or some other magical object. Would the Muggle be able to use it (or drink it, in the case of a potion)? To be clear, I'm talking about objects made by wizards and given to Muggle, so no Muggle making potions.
The closest thing I could find is an almost certainly non-canon Harry Potter skit for the 80th birthday of Queen Elizabeth II. In this, Hermione
blatantly violates the International Statute of Wizarding Secrecy gives an envelope that contains "a charm that can be worked by Muggle" with the following instructions:
Dear Prime Minister,
Happy birthday to the Queen from the students of Hogwarts. In view of this special occasion, we send you a charm that can be worked by Muggles, as long as they are in possession of a little borrowed magic, which we include in the envelope.
This is a limited one-time only offer. Stand up straight, point both to the left and the right, and shout the following phrase: “Accio Her Majesty’s handbag”.
Do these sort of magical objects actually exist in the canon Harry Potter universe, that can be used by wizards and Muggles alike?
