The Super Precision Gyroscope is made from solid brass, along with a light-weight aluminum enclosure. The included battery-powered motor is able to get the brass disc spinning up to 12,000 RPM for an indefinite amount of time, or up to 7 minutes if you detach it.
The gyroscope comes with a number of attachments allowing numerous configurations to perform scientific, educational or simply mesmerising experiments. [Included are] 2 x 50 mm long stainless steel extension rods, 2 x ball ends, 1 x slotted end. The rods when screwed together will extend 100mm, and can be screwed in other positions to create gimbals etc. There are 7 places on the frame of gyroscope that the attachments can be screwed into.
If you’ve ever played with a gyro you’ll know they can be a lot of fun, especially to younger children who don’t initially understand how gravity can apparently be messed around with like that. Granted, $129 may sound like a lot for what appears to be a toy, but all things considered, there are a lot of much worse ways to spend that much.
