I think these days that procedure has to be carried out by a licenced Piltwrangler (or Piltic Divination Master if you’re lucky enough to have one) and these devices are frowned upon. It’s easy to see why. The glanis nozzle is very unrefined and usually fails to form an adequate seal. There were quite a few injuries involving these in the early days and I think now you can’t actually buy them any more. Probably for the best.

Of course in my grandparents’ day, you’d make your own from an old Clemmy box and a length of spube.

The clear liquid in the hamonique (TM) tank converts your breathing-related actions into musical bubbles. These bubbles then disperse 22 seconds later, through the audio-fan (fan-like bit on the right of the face attachment) which you direct towards your cheek-ear-continuum.

The little blue tube, or ‘toob’, goes into your ear, and a little wire extends from said toob into your ear canal. This hijacks the auditory nerves, in order to feed a musiqal-echo (TM) directly to your brain.

It’s great stress relief. I hope these instructions help.
