interesting use for cigar smoke.

My BIL and I always smoke cigars in my shop or his. We were wondering just how efficient the charcoal dust filter was so we lit up a couple cigars and watched the particle counter. We smoked about 1/2 our cigars and got an average reading of around 40,000 ppm. We turned on the filter to find that it reduced the amount of smoke down to 13,000 ppm. It also tells us that the filter will remove particles as small as cigar smoke pretty well. I just thought you might find this use of cigar smoke interesting. Have a great day.

A friend of mine once tried to blow bubbles filled
with smoke. Although it was a little sloppy, with
the soapy water and all, he was able to accomplish
the feat after all.

Let me see... what was it that he was smoking?

The sad part of this is, 3000PPm is what's considered safe.
