Renovated in 2007, the nonprofit Liberty Science Center crams noggins with knowledge via live shows, IMAX viewings, and a diverse array of interactive exhibits. Starting Friday, October 7, aspiring mathemagicians can revel in the whimsical atmosphere of the Math Midway, where lasers, square-wheeled tricycles, and other equipment help familiarize children with patterns and numbers. The Touch Tunnel challenges crawlers with a pitch-black labyrinth, prompting visitors to use their nonocular senses and sonar-based superpowers to navigate its twists and turns. Little humans aged 2–5 can guide their adult charges through the I Explore playground, pounding out tunes on the rock xylophone, shepherding spheroids through the two-story ball machine, and chatting about the effects of the automobile on equestrian societies while building a car for the test track. Guests can also check with the welcome desk for the day's schedule of 20-minute Live Science shows, which focus on topics such as medicine and electricity.

Visually stunning and educationally meaty films illuminate the 88-foot domed screen of the IMAX theater, which offers seating for up to 400. Tornado Alley allows viewers to witness the cataclysmic power of an immense tornado, and Hubble explores the celestial landscape without the hassle of g-forces, space suits, or English-to-Vulcan phrasebooks. The center's digital 3-D theater harnesses three of the universe's 12 known dimensions for 20- to 40-minute films such as Waking the T. Rex: The Story of Sue, inspired by the largest tyrannosaurus skeleton ever discovered.

While Liberty Science Center features discounted rates for seniors, teachers, and other groups, this Groupon still represents the best deal available.
