I think we can all agree that Harry's potion ingredients are the best part of his potions, rather than the actual effects (though naked Harry and naked Ms. Rodriguez were very nice results). Sooo....
My wizard apprentice, Tyler Bryce, just game up with a new potion to give him more mental stamina in a protracted engagement. I give you, the Focusyn potion!
Ingredients: verbal exercise from a mental health book for sound, energy drink for taste, some no-distract fabric for touch, some finely ground glass powder from glasses for sight, peppermint for smell, and for mind - the episode from the simpsons where bart is on Focusyn to do better in school.
