Check out National Geographic's series "Brain Games" and "Fish Tank Kings" in this awesome DVD duo not sold in stores.

"Brain Games"

Hailed by critics as "tremendous fun" and a show that "makes science entertaining," Brain Games explores a world where time slows down, reality is an illusion and things aren't always as they seem: the world inside your brain. Host Jason Sila and top experts lead viewers through a series of interactive experiments to see how easily the brain can be fooled, uncovering surprising facts about how we process information, feel emotions and perceive the world around us. Get ready for lots of mind-blowing illusions, games, and challenges that will turbocharge your brain.

"Fish Tank Kings"

The dynamic "school" of aquarium specialists at Living Color in southern Florida are experts at fulfilling the wild aquatic requests of their fish-loving clientele. Going bigger and bolder than ever before, the guys "reel-in" a new "haul" of extreme projects that range from an aquatic oasis in the middle of the California desert to a pimped-out octopus exhibit at a New York zoo.
