• About an hour at your own pace, with explanations in Spanish and English
• Strollers welcome, though two rooms with steep ramps are not wheelchair accessible
• Timed tickets, usually cheaper online than at the door; you can move your date up to 2 hours before

More than 50 optical illusions and interactive rooms across 650 square meters, built to fool your eyes and your balance. Kids cross the Vortex Tunnel, where a steady walkway feels like it is spinning, try to stand straight in the Tilted Room, and pose in the Upside-Down Room for photos. Logic puzzles and holograms fill the rest.
