Hybrid Gyroscope Top: the Advanced Gyro is a unique design by @physicshack and can defy of gravity as described by the physics of gyroscopic precession and conservation of angular momentum. No pull cord needed, this unique design spins up via friction with a working surface (thin cardboard works well) and applying a circular motion to bring the rotor up to 1000s of RPM. Machined from solid stainless steel this top weighs in at about half a kilo, providing inertia that produces long spin times. A
