Harry Potter: "Ron, what's Seamus trying to do to that glass of water?"
Ron Weasley: "Turn it to rum. Actually managed a weak tea yesterday, before—"
Seamus Finnigan's spellcasting being interrupted by an explosion[src]

Eye of rabbit, harp string hum, turn this water into rum is supposedly the incantation of a transfiguration spell that turns water into rum. Its authenticity is dubious, as it has only been known to either create a weak tea, or an explosion.[1]

Known uses

Seamus Finnigan tried to cast it in 1991, and in his first attempt, he managed to make a "weak tea," before causing an explosion. The next day, he tried again several times, but only caused another explosion, creating smoke and blackening his face.[1]

Behind the scenes

  • It is unknown if this is a real spell or not, or simply a case of bangs-and-smells magic, although given that Seamus could turn the water into a weak tea, it is possible that it is, although he could not perform it correctly. Alternatively, it is not a real spell, and the turning of the water into a weak tea was purely accidental.
