You don't need to know anything.

We open on weekends and holidays. Private during the week.

A museum of illusions. Designed for adults who used to be children. No audio guide, no queue, no obligation to understand anything. You walk in, you walk out, you leave with one object you did not have when you arrived. Most visitors stay about an hour. Some stay longer. A few come back with someone, and lie to them about what is inside.

You walk in. You walk out. You leave with one object.
