Has anyone ever used a glass tube with some burnt stainless steel wool in the end of it? I tried it this way my first (only so far) time and it seemed to work amazingly well. I was only loading small doses, 10- 15mg, but it seemed like i could get the entire hit within 1sec or so of pulling. Does it work well with large doses? I saw a post somewhere about it but it wasnt very informative. Any info would be great thx!
