Exploding mendocino motor

This mendocino is turning so fast that the magnets come off ! It runs on 6V @ 100 mA () I still have to find 4 of the magnets. They must bee somewhere...... If you want to try this at home: DON’T TRY THIS AT HOME (magnets may come into your eyes or a window might break) Calculated fly off frequency = 112,54Hz (6752rpm) (radius= 10mm, magnets = 4gram and 20N holding force) But i think the frequency must have been higher (higher sound) so the magnets holding force has to be greater than 2kg ( : datas
