Incense.

[Plaidman]

I like the stuff. I really do. It makes me relax. Now I'm curious as to how many sticks does it take to really get a room smoky. I know its overload, but I seem to find the cloud soothing for some reason, and one stick just has a tiny amount of smoke.

[Taboo]

Hmm, not sure... try and avoid setting off your smoke detector, though, or it'll get a lot less relaxing really fast.

Google seems to suggest that some brands are smokier than others, so you might want to try out some new brands and see what works for you.

Depends on the size of the room and ventilation. When you set off the smoke alarm, it's too much.
FWIW, consider shopping for incense in a Chinatown or (Asian) Indian neighborhood market--better deals there.

That and they will besst know how much you need at once and what kinds would yould need for differing effects.

Mmmmmm, incense....I love the stuff, too! We use it at my church, and I just love seeing the clouds of it rising through the air.

I like using the little incense cones--leaves the ashes all in one heap, instead of spread out along a line, like the sticks.

Note: don't use an incense cone directly on any meltable surface...found that out when I perched one on the edge of my tub, lit it, and forgot about it...until a shower of sparks alerted me to the fact that the fire had burned down and fused the cone to the tub... Had to actually sand the dadgum tub down to get rid of the burn and melt marks.

Hmmm I dunno try 3 I guess....that isn't too much for you? One stick is enough to make me choke if there isn't enough ventilation.

I think about ten of the joss sticks from Chinatown. The big ones with the red sticks and yellowish tips to burn. And I mean the BIG ones.

1 is enough to clear a 700 square foot apartment of all smells.
