B125 - Dandelion clock

Approx. 32 x 22 mm, electroplated brass.
Hold this spinning top by lightly pinching it between your thumb (on top) and index finger (on the bottom).
Keep the axis of rotation vertical and bring it close to your lips until your thumb touches them.
Blow firmly onto the top from above. Once it is spinning fast enough, lift your thumb away
and let the top continue spinning on your index finger, or place it down on a suitable surface.
If necessary, use a flexible drinking straw to blow on it.
