A Walkalong Glider is basically a super light paper plane that you keep aloft by following it with a piece of cardboard or such. I’m finding plenty of videos like [this one](https://www.youtube.com/watch?v=VrgY_HHANfQ) that demonstrate how to make and fly one, but nothing really that clearly and concisely explains the aerodynamic principle at work
In: Physics
To be extremely simple, you’re pushing the air with the big piece of cardboard, and the air is pushing the glider. The glider wants to fall down, but because the piece of cardboard is angled up, the air keeps pushing it up. With the right technique, you can balance everything out and just keep it flying along by effectively just pushing it with that piece of cardboard.
