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
When you move a piece of cardboard behind the glider, it makes air flow over its wings, which helps keep it flying by generating lift. There is a name for it but for the life of me I cannot remember
