The sense of awe inspired by the sight of a towering T-rex is something none of us ever quite grow out of. Reignite your sense of wonder with a day of discovery at Maryland Science Center in Baltimore. Pay $19 for two adult single-admission tickets including IMAX access (regularly $42). The package includes access to exhibit halls, the star-studded Davis Planetarium, the demo stage where you'll watch experiments in combustion and inertia, and a classic IMAX show (with larger-than-life movies like Flight of the Butterflies 3-D and Ring of Fire). Or, pay $62 for an Adventurer family science center membership for four, with the same science center benefits, plus discounted IMAX access (regularly $125). Time to grab a map, or four, and see where the science takes you. Want more? Check out Maryland Science Center on Facebook.
