“I had no memory for incantations and my potions were a family joke! Now, after a Kwikspell course, I am the center of attention at parties and friends beg for the recipe of my Scintillation Solution!”
-- Madam Z. Nettles of Topsham in Filch's Kwikspell Course Brochure (CS8)
Effect unknown, but mentioned in materials for a Kwikspell Course marketed to Squibs.
References from the canon
- One of the students who found the Kwikspell course helpful wrote that people were now begging for her recipe for Scintillation Solution (CS8).
from Latin scintillatus, scintillare "to sparkle, glitter, gleam, flash"
It is unknown if the Scintillation Solution is a real potion, or just something made-up to fool Squibs into buying the Kwikspell Course (which J.K. Rowling said wouldn't work anyway). Squibs wouldn't know the difference, having never taken a Potions class. The word "scintillate" means to make something flash or sparkle, which would be appealing to a non-magical wannabe like Filch.
