Feature

SOOTHING AND RELAXING - Its aluminum mirrored finish and ellipsoid shape is known to relieve stress and be an aid with meditation. Give it a spin to enjoy the captivate sights and mesmerizing sounds.
PHYSIC-ALLY ENTRANCING - When spun at high speeds on its side, it will seemingly magically shift its position upright and vertical demonstrating angular momentum. Be amazed at how this unique shape can go from laying on its side to standing up with just one spin!
NO NEED TO FIDGET - In the course of its spin on the concave mirror, you will see physics take its place with Lissajous figures, electrodynamics, and the gelatinous ellipsoid effect. Shine some light on it and treat yourself to a fantastic light show.
CHICKEN OR THE PHITOP? - What came first, the chicken or the PhiTOP? Going back 150 years, physicists have been analyzing the cause of the rise of the center of mass of spinning. See if you can help figure it out.
ENJOYABLE FOR ALL AGES - Anyone from ages 5 to 105 will be ecstatic with what happens to this top after it has been spun. As it slows down, it provides an astonishing optical illusion with a relaxing sound while capturing the imagination of young children and adults. Have fun and challenge friends to see who can spin it the longest.

Description

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.
