Instructions
Measure in an inch from an end of the 8-inch long, 1-inch diameter wooden dowel. Drill a hole through the dowel at the measurement with a one-eighth-inch wooden drill bit on a power drill. Place one end of a 1-foot long string through the hole.
Wind the end of the string that has been pulled through the hole twice around the screw. Tape the string to the screw with a strip of duct tape.
Apply bonding glue to the side of the hole that the string has been pulled through. Press the screw against the hole and hold the screw in this position for 30 seconds before letting go. Let the glue set overnight.
Stand the 8-inch diameter bicycle wheel up on the floor. Run the end of the wooden dowel halfway through the hole in the center of the wheel.
Raise the wheel off the ground. Grip the end of the string. Hold the string out at arm's length high enough to keep the wheel off the ground.
Give the wheel a quarter spin clockwise. Let the wheel that is now a mechanical gyro continue to rotate on its own. Return the wheel to the ground when you are done.
