Paradox Museum London

A self-guided museum of optical illusions and paradoxes, where the rooms are built to play with balance, gravity and perception. Families wander through more than fifty interactive exhibits, from a zero gravity room and a tunnel that makes walking straight feel impossible to a reversed room and an infinity well. Much of the fun is in the photographs, and the rooms are designed for posing and taking pictures together. The museum says it suits all ages, and younger children tend to enjoy the illusions as much as older ones, though everyone is encouraged to read the short explanations of the science behind each effect. Visits typically take around an hour and a half. Seasonal themed events, such as Halloween trails and storytelling sessions, run at certain times of year. A boutique sells games, souvenirs and gadgets. Food and drink are not allowed in the exhibition spaces, so plan to eat before or after.
