Discovery Zero Gravity Levitator
The globe floats and rotates in mid-air by pressing the rotate and power button located on the back of the unit. Adjust the levitation height by slowly rotating the orange field strength controller on the front of the unit. The field balance indicator lights will flash green when balance is achieved and red when the globe is out of range. This toy uses the same principle that allows Mag-Lev trains to travel speeds of over 300 miles per hour! Product has been refurbished and has a fixed crack on the globe (as seen in photo).
