Without a doubt, 826 National's line of quirky stores and products offer the biggest and nerdiest bang for your charity buck. For example—at the Brooklyn Superhero Supply company you can purchase a set of vacuum suction cups for scaling the exterior of buildings. If the whole Spider-Man thing isn't for you, how about the power of invisibility? An "invisible" suit is available for the low price of $20,800. Of course, these products are meant as novelties only, but the proceeds benefit 826 National—a nonprofit tutoring, writing, and publishing organization for kids. The Suction Cups are priced at $19.
