Make paper airplanes that fly strong and straight and true. The secret: the "seven folds of genius" that form something called the Nakamura Lock. Kit includes step-by-step instructions, 35 colorfully patterned sheets of 8 ½" x 11" paper with the first fold already in place, tips for fixing common flight problems like the Straight Down Crater and the Swoop Up and Crash, and a simple explanation of how planes fly, because it's fun to know. A great little gift.
