The tubeless wind tube allows visitors to explore all the same effects as our Vertical Flyer, but without the tube. It produces a very solid and consistent column of air that allows you to experiment with aerodynamics and Newton's laws of motion. A playful and inventive way of exploring airflow, drag, symmetry, turbulence, air resistance and gravity. New designs are created by visitors based on the lessons of the first design and can be rapidly tested and improved. We developed two different ways of enjoying the exhibit, one is to keep the traditional open top concept or we have designed and tested a wooden insert that is perfect for centers that might experience the occasional exhibit climbing visitor. The Tubeless Wind Tube Exhibit has locking casters built in to allow for repositioning with ease.
