So much fun! - We had such a brilliant fun time. I had as much fun as my daughters! Lots of interactive items. The upside room was the best! Wasn't too busy so we could really take out time in each room.

Great fun! Great Staff! - My husband and I spent an hour or so here and had a lovely time. Staff were really friendly and informative & even helped with pictures! Good way to spend a couple of hours while in Krakow! Great location just a few minutes walk from the main square!

Great fun place. - Visited here and had a great time, would definitely recommend a great way to spend some time here. Lots of different things to see.

I can't trust my eyes! - Nice museum! Fun and interesting illusions. Great service from the people working there. Some illusions was really cool and interactivvee.

Quite a surprise - Funnier than I expected. Although some illusions were already known to us others were very entertaining. In addition, children were surprised by many of them. SUPER friendly museum staff both when explaining the illusions and when it comes to helping you with any of them to take a picture or tell you the best way to get in them. If you do not read the explanation of the illusions, the tour is done in a short time but it is worth it. I advise to stay for a while looking at the exhibition of pictures on one of the walls.

Fun and interesting... - Great way to spend an hour or so . The staff very helpful and keen to tell you more. Some exhibits are just plain fun but others really play with your understanding of the human brain

Great place to pass the time - 6 of us decided to visit this place on a whim, and what a surprise we had. I cannot remember the exact price for entry but I reckon it was around £7 GBP the upside down room and the photographic room were good too.

Great idea for a relaxing hour - Very nice museum, great to fill any hours of hole between one attraction and another. Not very big, it lasts half an hour, 15 minutes maximum, it's up to you.

It was ok - It was ok, it gave us something to do for an hour! We Wished it was bigger though as it was good for what was there. Thank you x

Fun place but smaller than expected - Staff greeted us in such a friendly manner and made us feel welcome straight away. We left the visit until late in the hope it wouldn’t be busy but visitors never stopped flowing, leaving us feeling a bit under pressure to move on quicker than we wanted to. It’s a fun place to visit but smaller than expected and we had seen many of their exhibits before.
