From the outside, Professor Wonder’s WonderWorks laboratory appears to have flipped completely on its head. When visitors enter the upside-down edifice, they must first pass through the psychedelic, spinning lights of the Inversion Tunnel, which turns the building right-side-up for families to embark on a full day of entertaining, educational activities. More than 100 interactive exhibits spark excitement around the natural phenomenon, including replica mercury capsules that visitors can climb into, a gallery of mind-bending illusions.

Some of WonderWorks’s hands-on displays allow guests to experience the aftershocks of the San Francisco earthquake of 1989, throw a strike against Derek Jeter, and lie down on a bed of 3,500 sharp nails without so much as a scratch. Additional activities include the Indoor Ropes Challenge Course, which exercises bodies and minds as challengers navigate three stories of swinging beams and suspension bridges, and the XD Theater 4D.
