Scientists agree that children are our future, which is why most children are sealed in time capsules with a flashlight and a stack of magazines. Give a child something he or she will really dig with today's Groupon: for $55, you get a passport membership at the Imaginarium of South Texas in Laredo (a $110 value).

The Imaginarium of South Texas stimulate the minds of youthful guests with a year's supply of curiosity-inspiring interactive exhibits, workshops, and events. Next year's rocket scientists and quantum theorists are exhaustively vetted with visits to the new permanent Thinking Tinkering exhibit, which invites junior brainstormers to enhance the design of missiles, art cars, and dryer-resistant teddy bears. Fulfill conductor-centric dreams in the Union Pacific interactive model train, complete with a matching miniature wooden set for toddlers, or foster fledgling creative impulses in the Shadow Room light and laser studio. Kids can get an early prep for the logic and physics sections of the SAT with the magnetic Wonder Wall, which features gear chains to construct and Sudoku puzzles to crack. In addition to a year of free admission for parents and their children, a passport membership grants discounts on birthday parties, workshops, and camps, entrance to special events, admission to or discounts on more than 150 other institutions that participate in the Association of Children's Museums's reciprocal membership program, and more.
