‘Hurricane balls’
These are great fun but how to do you make them and how do you make them spin?

better idea is floating anti gravity balls.
already for sale on amazon, i have some they work really well
make your own using
2 matching ball bearings about 12 – 15mm diameter.
1 3mm machine screw.
1 Biro pen, makes a great blow pipe.
A concave mirror to run it on, a flat surface will do but it will work better on a concave surface.
Superglue, this is optional but is a good idea to help lock the threads in place.
