After a lenthy series of renovations, Discovery Place is unveiling its newest interactive exhibit, Cool Stuff. It allows visitors to launch objects into the air, lie on a bed of nails, crush a garbage can, use a laser to listen to messages, and more. Now, that's pretty cool. Located across from Cool Stuff, is Explore More Stuff, an exhibit which functions as a lab-like environment where folks can explore and test the laws of physics, chemistry and engineering further. If you thought Bill Nye The Science Guy was the answer to your science problems, you ain't seen nothin' yet. $10 for adults ages 14-59; $8 for seniors ages 60 and older, and children ages 2-13; free for children under 2 years old. Monday-Friday, 9 a.m.-4 p.m.; Saturday, 10 a.m.-6 p.m.; Sunday, 12 p.m.-5 p.m. Discovery Place, 301 N. Tryon St. 704-372-6261. www.discoveryplace.org.
