MAKE YOUR OWN LEVITATION BALL

Junior scientists can learn about aerodynamics and gravity with the Kikkerland Newton’s Lab Make Your Own Levitation Ball Kit. Have fun blowing in the tube to keep the ball afloat. When air speeds up, pressure drops, and this pushes the ball back to the center of the airstream. Designed by Hector Serrano, it includes everything you need. No batteries required, just a little lung power! The assembled piece measures 4"H x 1-5/8"W x 7-5/8"L.
