I made my machine from a big Finlandia bottle. I remember the crystal patterns that were left on the inside of it. Good memories. Crazy aliens in toy rooms and all kinds of stuff.
Note: I wasted a lot of spice trying to use a light bulb, for conveniences make the machine. Never put a direct flame on the spice itself, keep the flame 1cm-2cm away from the bowl and suck in the heat from it. Once it's all melted in the wool and you already have two lung fulls, there's another two lungs fulls in there if you place the flame inside.
After some use, the wool itself without any spice is sufficient enouegh to take you to spiceland as it's laced from all the previous encounters. Pull it out and reverse it, there should be melted spice all over the damn thing :D
