Gyroscopes are fun to play with. Not all of them are created equal though. The RODA Gyroscope is an awesome desk toy that lets you observe the science behind gyroscopes. It comes with a base and rip cord too. The RODA is made out of a polished brass wheel and aerospace grade aluminum.
The RODA has bearings on the sides, so you can play with the gyroscope in a new way. The rip code and integrated gear let you reach up to 3000RPM.
