Learning about science in a museum is safer than experiencing it firsthand by accidentally ingesting a science textbook. Embrace science with today's Groupon: for $25, you get two admissions to the Body Worlds & The Brain exhibit at the Arizona Science Center (up to a $50 value). This exhibit utilizes timed entry, with up to 125 guests admitted every 15 minutes; the Groupon cannot be used for phone or online reservations but can be exchanged in-person for advance tickets. Plan a trip to the exhibit anytime between now and this Groupon's expiration—May 27, 2011—and drop in before the date of your visit to redeem and ensure entry in your preferred time slot.

The world-traveling exhibit Body Worlds & The Brain has captured the wonderment of global audiences, giving viewers an inside-look at the human body. The detailed collection's population of real human bodies have undergone plastination, a process invented by Dr. Gunther von Hagens that perfectly preserves all organs and tissues of the specimen while allowing doctors to arrange it in any dynamic pose. Each subject is sans skin, exposing muscle structure, and bone formation. Part sculpture, part health lesson, Body Worlds & The Brain also allows patrons will get up close and personal to smoke-damaged lungs and brain matter affected by neurological disease. Purchase an unlimited amount of Groupons with today's deal to schedule educational family outings or spicy double dates.
