Twist the Stirring Rod and Discover the Secret Classroom
The central play function lies in the stirring rod mechanism: twist the stirring rod on the cauldron and the vessel opens to reveal the hidden classroom within. Inside stand removable desks, a blackboard with recipes and shelves full of potion bottles. The LEGO ingredients cover three famous potions: Wolfsbane Potion, Polyjuice Potion and Love Potion. Professor Snape oversees the lesson with his typically stern expression, while Hermione, as the top student, brews the potions to perfection.
When closed, the cauldron looks like a steaming brewing vessel complete with bubbles and green contents. As a display piece it works as decoration on a shelf or desk. The 20 cm height and round shape make it an unusual eye-catcher that also doubles as Halloween decor.
Patronus and Portrait for the 25th Anniversary
For the 25th LEGO Harry Potter anniversary the set includes Hermione's otter Patronus as a buildable figure and one of 14 collectible Hogwarts portraits. The Patronus figures and portraits are spread across various sets in the anniversary range, encouraging collecting. The otter Patronus is Hermione's personal protective charm, which she learns to cast in the fifth book as part of Dumbledore's Army. The set thus links the dungeon Potions lesson with one of the most important spells in the entire series.
