Don't throw it...blow it! This kit comes with everything needed to make a fleet of puff-propelled precision flyers. Follow the step-by-step instructions to fold a custom-designed paper airplane, attach it to a launch straw, and with one quick breath send it soaring. This educational book gives you tips for getting the best performance from your jets, based on the science of aerodynamics. You get enough paper to make 10 each of five different jets, from the mysterious X-88 to the aptly-named Spitfire, plus 10 more bonus sheets. But the fun doesn't end when the pre-printed paper is gone; a sturdy plastic stencil lets you trace and cut out planes from your own paper. How many jets can you make with this book? The sky's the limit! Includes a 60 page book, 60-cut-out planes, 10 jumbo straws, 10 custom rubber nose weights, four standard straws, and a plane-body plastic stencil.
