Thanks very much!
I watched a member's youtube video last night on heat management and it explained alot. I think my main issues are packing too much tobacco in the bowl and the size of the holes in my foil. For my next session I'm going to use a pin to prick the holes and make sure that there's a decent gap between the tobacco and the foil. The AF Bubble Gum that I smoked the other night got roasted and it sucked, haha...as soon as I put the coals on I could hear the tobacco sizzling underneath. Then about 10 mins later when I removed the coals I got a tiny comedic black cloud eminating from the bowl. Reminded me of the old Warner Bros cartoons where I character would catch fire and then start sizzling after being put out with water!
This forum is great btw, thanks again
