Once we’d bought the tickets, there was nothing left to do when we arrived on the day. The lady scanned them with her phone, gave us a wristband, and that was that. The museum—which, to me, isn’t really a museum but more like a small city amusement park—was nice, but too crowded, and I was frustrated that I couldn’t buy a miniature version of the (unfinished) puzzle that was upstairs. But it’s worth a visit.

Overall, it was a very positive experience; all the staff were incredibly friendly, knowledgeable, and helpful. There were a few attractions that weren't great, but overall everything was very interesting.

Very entertaining, my two grandchildren aged 7 and 9 loved it. They tried to understand the different optical illusions and are already planning to go back. Well done to the whole team, who explain everything with great patience and attention! And help you take great photos.

Very engaging for the children, and also the parents. The exhibits were great and showed a fantastic insight into the paradoxes of life. The illusions were great as well. My family thoroughly enjoyed the experience.

Step into the Paradox Museum and immerse yourself in 90 interactive exhibits that challenge your senses, including the "Ames Room" where you’ll experience altered perceptions of size, and "The Infinite Tunnel," an optical illusion that creates the sensation of endless space.

Explore the world’s largest collection of paradox-based exhibits, featuring optical illusions like "The Vortex," which creates a disorienting spinning effect, and the "Upside Down Room," where gravity seems to defy logic.

Enjoy up to 80 minutes of exploration through immersive installations like the "Mirror Maze," where reflections confuse your sense of direction, and "The Gravity Wall," which will leave you questioning the laws of physics.

It's too complicated for someone my age, and I don't like having to download the app onto my phone, which, by the way, doesn't have enough storage space anymore!

It was a fun experience with some really cool attractions. The website mentioned it would be a 90min experience but we got through in just over 30mins and done every interactive item except the "defy gravity" as the line was long
