I did not create the tumble wing or walk along glider which is why there is no charge for this activity. I created a powerpoint presentation to help students construct it and understand how it works. There are links to the original site and pattern and to video clips that explain how it works. I have assembled images to aid my students in building the device.
This tumblewing or walk along glider is a fun activity. Students make a tumblewing out of a piece of phone book paper and learn how to control its motion by allowing it to surf on a wave of air they create by walking with a piece of cardboard or a white board.
You could make this more scientific by having students measure time in the air and the horizontal distance the device travels without a cardboard push, drop them off the railing for a two story building and look at rotational speed, time and distance for larger and smaller versions as well.
