Explaining The Universe on Instagram: "A gyroscope is a device that stays oriented in the same direction by using the stability of a rapidly spinning wheel. When the wheel spins, it builds angular momentum, a kind of “rotational stubbornness” that makes it resist any attempt to tilt or change direction. Because of this, if you push on a gyroscope, it doesn’t tip over the way you expect—instead, it moves at a right angle to the push, a motion called precession. This unusual stability makes gyrosc
