This imaginatively executed science museum—its driving concept is "Ideas You Can Touch"—is right across from the New Mexico Museum of Natural History and Science. ¡Explora! bills itself as an all-ages attraction (and enthralled adults abound), but there's no question that many of the innovative hands-on exhibits such as a high-wire bicycle and a kinetic sculpture display are geared to children. They offer big fun in addition to big science (and a good dose of art as well). While its colorful Bucky dome is immediately noticeable from the street, ¡Explora! also features a playground, theater, and a freestanding staircase that appears to "float" between floors.
