When I was about eight or nine my parents took us to Holland to visit our extended family. Visitting my grandfather was always a treat, he’d make the most awesome paper airplanes, and we could fly them off the balcony of this 7th floor apartment. I’ve been trying to figure out how to make them ever since, and haven’t figure out how until today, after the 153rd paper airplane for Noah refused to fly properly. This site has the recipe. It’s a lot harder than it looks, but they fly!
