Step 6Who Makes the Coffee?
To work the gadget, leave it plugged in but with the mains wall switch turned off. At coffee time, turn on the power and wait with bated breath to see whose name stops under the pointer. Turn off the wall switch.
If the disk stops precisely on a dividing line, coffee duty will be decided by a round of 'rock paper scissors' between the two people indicated.
The selected person must now go and make the coffee, or, in the case of those unfortunate enough to have one, persuade the drinks machine to produce a beverage which is almost, but not quite, entirely unlike coffee.
As the Kaptin says below, this isn't limited to coffee making. With different disks you could replace throwing a dice, play roulette, make vital life decisions etc. Your imagination is the limit!
(Some drive motors seem to have a couple of dozen angles they prefer to stop at. If you're thinking of using more than ten or so sectors, don't use one of these as it will skew the randomness. You can feel it as a lumpyness when you turn the disk by hand.)
