If you insist on smoalking base without a proper pipe, you can use the method described above, but try to avoid plastic and aluminium foil. If you must do it this way, use a brass end cap (from your local hardware store) instead of foil and a glass/metal funnel.
Thus the process would be as follows:
1) place your spice in the brass cap and place the cap on a surface that won't burn (think along the lines of glass table top or kitchen sink)
2) hold the funnel in your mouth
3) slowly heat the spice with a small torch
4) as the spice begins to vape, inhale, using the funnel to catch as much of the vapour as possible
That being said, BongWizard likes (or maybe loves) changa! He has a special homemade glass bong dedicated to smoalking changa

I'm not a big fan of SWIM. I mean, I've never met the guy, but any time I hear about him, he's doing something sketchy.
