The Clockwork Aquarium! project by mjsmiley is the latest project to achieve 10,000 supporters on LEGO Ideas. The aquarium features a number of fish along with some plants and sand but the main play feature is the working internal mechanism that makes the fish “swim” about. You can check out how the aquarium works in the video below.

The project now joins Queen: I Want to Break Free, Seinfeld 30th Anniversary, The Legend of Zelda: BotW Stables, Planet Express Delivery Ship, Ratatouille: Open The Doors!, LEGO Typewriter, The Legend of the BIONICLE, The Huascar, Winter Chalet, Toronto Rocket Subway Train, and Home Alone McCallister’s House as the projects to reach the Third 2019 Review Stage.
