- "The Revealing Charm will reveal invisible ink and messages hidden by magical means. Simply tap a book or parchment with your wand and any hidden message will be revealed. This spell is more than sufficient to overcome the basic concealing charms and so is a favourite of parents and teachers alike."

- "She tapped the diary three times and said, "Aparecium!""

Behind the scenes
- It can be assumed that this spell, like several others such as the Summoning Charm, can be blocked by the effects of the Horcrux-making spell.
- In Harry Potter and the Prisoner of Azkaban, Severus Snape possibly used this spell nonverbally to attempt to force the Marauder's Map to display its content, while aloud demanding that it reveal its secrets.
- In the Nintendo DS version of the video game adaptation of Harry Potter and the Goblet of Fire, there is a minigame called Aparecium Pairs, the goal of which is to rub the DS's bottom screen within a time limit to reveal a card or group of cards matching the one(s) on the top screen.
