Going Deep With David Rees: The Tumbling Wing
Let the paper plane guy show you how to make a paper plane with a twist.
I had posted this in paper airplane section but probably belongs here. Getting the Tumbling Wing to work properly can be difficult but very rewarding when you get it working. First work on getting the Tumble Wing to spin straight ahead which means tiny adjustments to paper edge and learning to release it correctly. In a summer class I taught the kids had trouble with this: http://scienceguyorg.blogspot.com/2014/07/trying-to-learn-tumblewing-not-easy.html
Then you have to adjust the speed and angle of the paddle as you walk forward, if you go too fast it can go behind the paddle, too slow not enough lift.
