- Prepare a glass piece to be fitted to the intake of a bubbler.
- this can be accomplished either by using a glass piece small enough to fit inside with a gasket fitted to provide a seal or by attaching the piece with a small section of tubing.
- 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.
- After it has cooled, stuff it in the larger end of the piece, and stuff it down toward the end designated for heat application somewhat tightly, and so that a part of the mesh is exposed.
| NOTE |
|
| The water in the bubbler acts only as a heat-sink and will not absorb a significant, if any, amount of product, as the freebase product is not very soluble in water; however, the use of ice in cooling should be forgone, as it may cause the premature precipitation of product within the chamber.

| Notes on Administration |
|
- To load, simply place a measured dose inside the piece push on the plug and carefully melt into the plug by feathering with a flame or other heat source.
- A butane torch is a preferable heat source for the operation of this piece.
