In this Instructable, we are going to make a Gyro wheel.
A wheel that can be balanced on different objects while it's spinning.
In the "gif" picture above, you can see a 1kg/2.2lbs wheel, spinning vertically around the rope.
If you have not seen a gyroscope or you're not excellent in physics (that would be me), you would expect that the wheel should spin horizontally.
I got this 1kg/2.2lbs wheel. Not that the weight matters, I just wanted to know how heavy it was.
I decided to use a little stick for the axle.
I drilled a hole and pushed in a match to hold the wheel.
Great alternative for the match is a hair pin.
I put on the wheel and marked a point for the second hole.
After drilling a second hole, I covered the area between the holes with electrical tape, so it's a tighter fit.
I pushed in the second match and used a glue for the extra security.
The wheel was ready.
I spun it with an angle-grinder and put it on the bottle neck to see the "magic".
What I learned from this project:
If you use a wheel that heavy and small, make sure to do it outside and wear a protective equipment.
I dropped it a few times - it nearly hit my computer.
Touching a wheel that is spinning so fast is the same as touching your bicycle wheel while you're riding it.
If you don't have gloves and you accidentally touch the wheel - be prepared to look for an adhesive bandage :)
