About LEGO Cauldron: Secret Potions Classroom
Building this 652-piece set reveals a clever dual-purpose design where the exterior cauldron conceals a detailed potions classroom within. The construction centres around creating an authentic bubbling cauldron that opens to expose the secret classroom inside, complete with removable furniture and magical accessories.
The hidden classroom features interactive elements including movable tables for easy access during play, a blackboard, and an array of potion bottles filled with LEGO ingredients specifically designed for brewing Wolfsbane, Polyjuice and Love Potions. A stirring stick mechanism allows builders to reveal the classroom interior with a simple movement.
Minifigures and Collectibles
The set includes Professor Snape and Hermione Granger minifigures, each equipped with wand accessories for recreating Hogwarts potions lessons. Notable collectible elements include Hermione's Otter Patronus, part of the 25th anniversary Patronus collection, and one of 14 collectible Hogwarts portraits that span the broader range.
Display Specifications
When completed, the cauldron measures 20 cm high, 14 cm wide and 13 cm deep, making it suitable for both play and display purposes. The design works particularly well as seasonal decoration while maintaining the interactive play features that define the building experience. Suitable for ages 10 and up.
