Spread out among 132,000 square feet and three levels are a variety of permanent and temporary exhibits that represent the museum’s goal of innovative inspiration. The recently opened, hands-on, and interactive exhibit Invention at Play examines the evolution of playtime from the hoop-and-stick of yesteryear to the portable holographic virtual wristwatches of today. The art, film, and music-focused Tech Virtual Test Zone conceptualizes ideas from the virtual world of Second Life with interactive wonders such as the Wall of Musical Buttons. The Wall allows visitors to experiment with note intervals in familiar musical melodies, and Mashup Masterpiece gives visitors the ability to add their own creative modifications after observing an artist's artistic process. Aspiring weatherpersons can learn about the powers of wind, water, and sun in Green by Design, or budding Beakmans can perform various science experiments in the Exploration Gallery. Keep the stimulation going while giving tired legs a rest with the included educational IMAX movie. Check out current offerings such as Arabia or Under the Sea or peruse the schedule for other upcoming shows at The Hackworth IMAX Dome Theater.
