Whether you want to wind down or wind up, this tube is soon to be your favorite automatic aerodynamic magic. Like the giant bubble fan from Willy Wonka’s factory, this easy to make wind tube is great for exploring what flies, spins, tumbles, soars and falls, all easily mobile for the teacher/parent/adult/kiddo on the go.
There are other tubes out there in the world, and this one is inspired by this one. I wanted to make it sturdy, upright, easy to roll around the class, so here we go!
