5H20.22 - Levitron (TM) - Levitation Using Permanent Magnets
The apparatus must be leveled for each use. The top may need to be rebalanced after each use also. Use the plastic starter table and start the top spinning. Once the top is spinning you should be able to raise the plastic until the top floats in space.
