The visiting Mythbusters exhibit at MOSI is ending May 8 but not before making a big bang on Sunday. Yep, University of South Florida engineering professors are going to blow up stuff to salute the special touring exhibit that has been at the Tampa science museum for the past three months. On Sunday from noon to 2 p.m. engineers will show some creative combustions while teaching the science behind the reaction (from a safe distance). The show called "1, 2, 3 … Oops!" is included with MOSI admission. This is the traveling exhibition's only stop in Florida. Filled with hundreds of items from the set of the quirky Discovery Channel show, it has stations set up so visitors can confirm for themselves some of the show's most popular experiments. Tickets for MythBusters: The Explosive Exhibition, which includes admission to MOSI's regular exhibits, are $24.95 for adults, $21.95 for seniors and $19.95 for children 2-12. MOSI member tickets to MythBusters are $11.95 for adults and $9.95 for children. Visit mosi.org for more information. MOSI is at 4801 E Fowler Ave., Tampa.
