Funny Ballon Animal

One thing I forget to tell about the tube, is how its kept in place now that the early scaffolding has gone. It's a balloon trick!

You see, there's a wee balloon on the inside that gets inflated, if you can inflate something with water, so that it acts like an anchor on the inside. Sort of like a harpoon, Dad? asked Keir - well yes, but with smoother edges. On the outside I have a 'bumper' that I need to keep close to the surface -except for the daily twist and clean routine - and that way I've a tube retaining mechanism.

It seems though that the water inside gradually evaporates, gets out or generally reduces in volume - they didn't seem clear on how - so I get to use another valve to extract last week's remains and top up with a new 5ml syringe. Sciencetastic.

  1. Your positive attitude deserves more than my platitude
    And your upbeat demeanor is grand
    if I ever get ills, need to take bitter pills
    I'll face it with your jocular brand


    Keep plugging away for that fantastic day
    When you sit down with family and friends
    For a feed that wont make your mouth wince,
    You can quaff beer and wine,on fine vittles you'll dine like Owl and Cat....with slices of quince
