Precision Gyroscope

The Tedco Precision Gyroscope is engineered with mini-bearings. Heavy weight and good balance guarantees the longest spin of any toy gyroscope we have tested. Wind it with a pull string like a top, or get it spinning with the easy-to-use plastic geared T-handle. Watch it balance on the rim of a glass jar or tie it to a string and observe it hang at a right angle to the string. Made in the USA. Colors may vary from photo. Insider Tip: A drop of "3 in 1" oil in the bearings makes it work better.
