Flowering Hurricane Balls

You may already be familiar with the normal Hurricane Balls. However these are something special.

There are the usual two ball bearings that have been welded together; but in this case, instead of being shiny, the ball bearings have been milled so that they have a fine pattern of lines on their surface.

Secondly, there is an unusual miniature LED torch that when you switch it on, continually changes, or morphs, from one colour to another. In addition, it is also flashing on and off. This is not visible to the naked eye if you hold the torch still, but if you wave the torch about, you can see that the light appears as an intermittent line, it is not continuous.

By spinning the Hurricane Balls on a smooth surface and then shining the torch onto them as they spin, an extraordinary pattern appears and changes before your eyes. Rather like a flower opening and then closing, first in one colour and then another. As the Hurricane Balls gradually slow down, the flowers rotate one way and then the other, growing and then diminishing, and always changing colour, due to the colour morphing LED torch.
