The small top will spin around the handle like a wheel. The speed depends on your skills... With a little practice you will learn the hand movements, and the top will go faster and faster until it is shot from the handle and continues to spin on its own.
When you mastered the movemenst you can practice to catch the casting tip again with the hand part and keep it spinning.
Acceleration requires some skill and is well suited as a learning toy to promote motor skills and coordination. This toy is not only suitable for children, but also suitable for occupational therapy of older people.
There are some great Youtube video's to see the Jippi spinning top in action. To give you an idear of what you can do with the toy.
Even only moving it around in the handle is a great relaxing feeling.
