Perhaps the only thing, despite
what the commercials say, that does
look cool when you are
smoking. This is a small circle of smoke created by carefully blowing
smoke out using a
time-tested method. (see:
How to Blow Smoke Rings) The ultimate smoke ring is
blowing one large one, and then a smaller one through the middle of the first.
And no, even though I have tried very hard, it is impossible to blow smoke letters like the tripped-out, hookah-smoking caterpillar in Alice in Wonderland.
