#### Please observe all safety rules when spinning things. Perhaps do not spin them too fast, just fast enough to show the behavior of a gyroscope.

Few things are as captivating and mind-boggling as a toy gyroscope! Now, if you have a few 608 bearings (22mm, 8mm, 7mm) such as those from a fidget spinner or skateboard, you could make a simple string-driven gyroscope using the parts in this design. You need 6 bearings; at least one is of decent quality. If you like, two bearings can be installed in the middle (at top and bottom) for increased stability. Be prepared. It spins fast.

**Here is the story**. Kids like playing with those fidget spinners, which are technically a gyroscope. I saw a kid trying to spin it faster using a rope, to no avail. So I brainstormed a bit and designed a wall around the central bearing and then added a few grooves to enable string wrapping. With that “wall,” we can now wrap a string
