This gyroscope is an improvement to the tedco gyroscope and is probably the most precise toy gyroscope for its price. Tiny ball bearings and good balance keep the gyroscope spinning for several minutes. It can be started with a string or a T-handle, both of which are included along with a balancing pedestal and instruction booklet. Durable enough to withstand hours of classroom demonstrations. Recommedned for ages 8 and up.
