Note:

This page tracks the development of amor_fati's Mini-Machine Bubbler Stem[1]. The content is to remain accurate as such.

The advantages of The Machine is that having a copper or steel mesh between the product and the flame protects the product from burning as well as distributing the heat of the flame evenly and rapidly to the product. However, most have a difficult time making one in the recommended fashion. Also, many prefer to cool their vapor by bubbling it through water prior to administration, and a properly constructed "machine" does not easily facilitate this.

Procedure for Construction

Materials Required

Equipment: Butane Torch (same one that will be used for vaporization) Glass Dropper Stem (either from a pharmacy OTC or an online vendor) Copper or Stainless Steel Pan Scrubber (as long as the metal doesn't burn of melt with the use of a butane torch) A Thin Metal Rod (even a paper clip would probably work) Pliers 2 Rubber Gaskets (found in the plumbing section, must fit snugly around the dropper stem)

1. Carefully crush the nozzle of the dropper stem with pliers, leaving a slight portion of the nozzles curve.
2. Heat the broken end of the stem with a torch so that the sharp edges are dulled and any cracks sealed.
3. Cut off a piece of the metal scrub pad, hold it with pliers, and burn with a torch under an oven hood until no more smoke is emitted.
4. After it has cooled, stuff it in the larger end of the dropper stem, and use a thin metal rod to stuff it down toward the nozzle-end somewhat tightly, and so that a part of the mesh is exposed out of the broken end.
   • experiment with different lengths of plugs to determine what size is optimal for preventing runoff and providing even, rapid heating.
5. Fit two gaskets on the stem far enough from the plug to avoid heat but far enough from the other end to provide a stable stem.

Administration.

For use as a portable vaporizer, attach the nozzle of a straight dropper stem to the open end by a small section of latex tubing.

1. Place product into the open end of the stem and stuff down to the plug with a thin metal rod.
2. Feather the glass with a torch until the product melts into the mesh plug.
3. Insert the stem into a bubbler as a bowl, with the open end in.
4. Use a torch to apply heat to the mesh plug while drawing air through the bubbler.
   • keeping some distance with the torch is recommended to avoiding burning or overheating.

the Use of a Mini-Machine Bubbler Stem with an Improvised Labware Bubbler
For those unable to easily obtain a proper bubbler. The mouthpiece is a longer dropper tube (Pasteur pipette) connected to the nozzle of the vacuum flask by another segment of latex tubing. The segment of latex on the top of the inlet is folded over itself to make a wide even rim to facilitate a proper seal with the glass rim of the dropper stem when held in place.

Notes

• The second gasket generally makes the piece safer to handle--especially if used as a pull stem--while the other provides a seal.
• For group sessions, it would be easiest to prepare an individual piece for each person so that dosage can be more easily regulated.
• When handling the piece after heating, handle by the gasket and avoid any part of the heated portion of the glass coming into any contact with hard surfaces.
• A good way to cool down a stem is to roll if rapidly between the palms, drawing the heat off the glass.
