For everyone struggling with moulding for a big fat one.
You will need:
(A microwave, a cup, suppositorys and fridge {optional} - if you can't work out why, read other posts first)
A roll of cling film, though foil sort of works...
A prodding device (Spoon handel, pen, finger etc)
Take a square of cling film, eg 8x8 inch and lay out flat. (or a couple of layers stacked if your film is low quality.)
In the middle of the film stand the prodding device upright by the bluntest end.
Take each corner of the film and hold at the top of the prodder - the film should be loose and "star shaped"
Carefully insert the prodder and film into the end of the cling film tube to the required depth.
Peel back the corner of the film from the top of the prodder and seal over the top of the tube and remove the prodder.
Gentley blow into the tube to inflate the film.
Inspect and when happy pour in mixture.
In exchange for this method: Has anyone had any success with additives in the mixture, its something I've thought of and not tried as I was worried about ruining the glycerin, im thinking for sensation or stimulation or irritation.
Maybe mint oil, chillie flakes, menthol????????
