If you have a little guy/gal with even the slightest interest in model planes, or paper planes, or just things that fly, then you should get this paper airplane book/kit. You probably know how to fold like 3 paper airplanes and think that's good enough, but this book has so many seriously cool paper airplanes that I had no idea you could make that it puts the 3 planes I thought were cool to absolute shame. And most of these planes fly great too. Some of the fancier looking ones don't fly that great, they look cool though, and are fun to make, but some of the larger models fly super good, I never would have thought there were so many ways to fold an 8.5x11 piece of paper and make something that flies this good. Plenty of paper included but note you can just use computer paper and they work just as good. The directions are easy to follow and the planes all turn out great. Though some fly better than others for sure, most of the ones in this book are keepers. Some are fast, some are slow, some float, some do loops and are unpredictable, but each one is unique. The launcher is kind cool, but we find just throwing them works best. But you an put the rubber band in them and launch them too, it works fine, again, some planes work better in the launcher than others. Love the cool names they gave each plane too. My son and I have been having a blast making them and flying them and having competitions to see whose plane can fly the farthest. So ton of fun, can definitely recommend.
