This all-ages attraction combines physics, optics and art to shock and stimulate the senses over 400 square metres of mind-bending exhibition space. The interactive displays encourage you to play and ponder the mysteries while painting with light, walking on the ceiling, shrinking your size and more. Fun, unforgettable and highly photogenic, friendly staff are on hand to further explain the science behind the illusions and even help you with that Instagram content; they also offer guided tours in English, Polish, Ukranian and Russian.
