Here’s the deal.
Get a drinking glass at least a 14-16 ouncer, run it under water and place it in the freezer. You want it to frost over like a good icy beer mug. It has to be cold enough, so let it frost.
Use a straw to blow a good shotgun hit into the glass, blowing smoke into the bottom. Put something over the top, the smoke will settle on the bottom. Happens pretty fast. Then, you turn up the glass and inhale off the rim of the glass, through your mouth,taking the entire hit.
Smoooooth and cool..and then..your head blows off..try it!
