What is the PhiTOP? It is a prolate ellipsoid with a highly specific ratio of length/width. It is a unique spinning top. It is a beautiful kinetic artwork. It is an elegant miniature sculpture. It is an effective stress reliever. And it demonstrates a bevy of scientific concepts from disparate studies in the field of physics! Spin it on its side at high speeds and watch as it seemingly magically rises to an upright/vertical position as it turns! The set also includes a concave mirrored surface to help you get the hang of your spinning technique. Makes an excellent conversation starter, and a great and unique gift for all ages.

This will help!!!
This is not a review, it’s a suggestion for those struggle to get it to stand up! The physics of the phitop means that it gets torque from the friction between itself and the surface it is spinning on - try spinning it on a wooden table top or piece of paper and it will be much easier to do! I think the supplied mirror is for display purposes 😉
