The Galleria is filled with stores trying to sell you stuff that you never knew you needed, but at least there's one whose merchandise can help you learn a thing or two. The Discovery Channel store is, not surprisingly, an offshoot of cable's Discovery group of networks (which includes The Learning Channel and Animal Planet), a group that is home to lots of World War II documentaries and goofily addictive shows like Junkyard Wars, where two teams are locked into a scrap yard and compete to build the best cannon, or amphibious vehicle, or whatever, from materials on hand. The store is a perfect place to go if you have to find a birthday gift for some kid you barely know; there's everything from plush stuffed animals to Pond Scum Soap to informative scale models and astronomy kits. Since it's in the Galleria, by definition it's pricey, but a visit to the Discovery Channel store is a much better option than your standard toy outlet.
