The handle hangs in air (and spins if started). Onlyon one side it touches  the transparent bareer. 

Both in handle andin the horizontal suport magnets are hidden. These magnets have a well-definedgeometry - of the same polarity in the correposponding positions in the handleand the support - pushing the handle up and pulling it towards the bareer.

If the handle is placed "upside-down", i.e right and leftdirections inverted, it sticks to the support - two corresponding magnetsare of the opposite polarity.
