Tiny Leaf Blower Toy: this little battery operated blower is great for experimenting with the Coandă effect. Here an air stream attaches and wraps around the styrofoam ball trapping it in the center of the stream. As the air changes direction to flow around the ball, momentum is imparted to push the ball against gravity and levitating it in equilibrium. A cylinder constrains the airflow and temporarily changes the dynamics which allows the airstream to push the ball up and out- and if one aims carefully the ball will fall back into the Coandă effect trap. ➡️ Follow the link in my profile for info on where to find this and other amazing items featured here on
