This was a gift from Tim Rowett to John Davenport and other attendees at James Dalgety’s puzzle party on 9 June 2001. The idea is to spin the two ball bearings (which are welded together) on a flat surface, and then speed up the spinning rate by blowing on them using the pipe. The balls can be accelerated to an incredibly high rotational speed. The Hurricane Balls were sold by Grand Illusions with LED torches to create amazing illumination patterns.

Purchased by John Davenport from Tim Rowett (Grand Illusions) at the 2008 International Puzzle Party 28 in Prague. When you tilt the card up and down, the letters G – I move across the card from left to right. Presumably this stands for Grand-Illusions.
