SUPER FAST 12,000rpm Electric motor startThe included Quickstart® electric motor spins the gyroscope effortless up to an impressive 12,000 revolutions per minute. The motor can be fastened to the gyroscope with two screws providing hours of continuous use or it can be used to briefly start it and quickly detach, allowing you to perform experiments for as long as 25 minutes. The electric motor makes it easy and quick to start gyroscope, with speeds you would struggle to achieve with string pull start. The motor has its own battery pack that requires 4 AA batteries. Batteries are not included. |

SUPER SMOOTH computer balanced diskIf a spinning object is unbalanced it will vibrate. A gyroscope needs to be balanced, just like a wheel on a car is balanced to ensure a smooth ride. The super gyroscope disk is made from brass and machined to microns precision, ensuring the disk is incredibly symmetrical and well balanced. Despite the brass looking perfect on the surface, it is an alloy, made up of a number of other metals and these metals are not always evenly dispersed resulting in a very slight non-uniform weight distribution. To correct this, the disk is then computer balanced to an impressive 250th of a gram accuracy! Thus giving the gyroscope a highly balanced, super smooth feel, longer spin and even quieter operation. |

SUPER SUSTAINED spin times of up to 25 minutesCarefully chosen miniature ultra-low friction stainless-steel ball bearings allow it to run smoothly and almost silently for up to 25 minutes, allowing you to perform the experiments and tricks you want to do without having to reattach the electric motor. Please note: Some experiments and tricks remove quite a bit of energy from the gyroscope. This will reduce spin times. |
