The Sloomoo Institute is set to open a 17,000-square-foot slime-themed attraction at 22-24 Clinton St. on November 6, 2026. The new facility will feature interactive sensory stations and slime-making experiences following a previous run of a smaller pop-up in the area.
Why it matters
The expansion arrives after a successful year-long pilot of a smaller attraction nearby. The permanent facility aims to serve the local community by transforming a long-vacant retail space into an interactive entertainment destination.
The new site will support hiring for up to 100 positions and offers general admission starting at $35.99. General admission is $35.99 while VIP tickets start at $65.99.
