A wobble/dancer is a spinning top with a very high centre of gravity.
This makes it very difficult for it to straighten up while spinning top.
While the body of the spinning top rotates more or less on the spot,
the ends of the spinning top's axis describe a circular path.
A very beautiful, dancing effect.
The difficulty is that the spinning top has to spin very fast.
Hold the spinning top body with the thumb and forefinger of one hand and flick the spinning top with the other hand.
Most wobblers have different spinning tops at the ends of the axles.
Start by spinning on the blunter tip.
With a little practice, you will also be able to start the wobbler at a shallow angle on the pointed side.
