Need idea to test air flow in shop.
 

I looked into the "smoke tubes" from Grainger but they're $100.00 for
a kit. I know there is something cheap and relatively safe (can't kill
anyone except management) I could use to figure out air flow in the
shop.

Ideas?

Fill a cloths iron with anti freeze and set it on steam. It will
produce loads of smoke and though crude might fill your needs for the
price.

COOL Idea, How toxic is the smoke?

Try smoldering hemp / manila untreated rope , much safer than the
anti-freeze idea. Old furnacemen used to use it for checking drafts.

The simplest way I know to make air flow visible is to weight a mylar
Helium balloon to neutral buoyancy and release it. Latex balloons leak
too much to stay up very long.

How about walking around with a lit cigarette in your fingers (not in your

Dry ice?
Put it in a container with a small orifice on a nozzle. Add some colored
water.

Mcmaster has individual smoke bombs.

An incense stick works real well, putting out a fine trail of smoke that
will map your air currents. Cheap too.

Wal-Mart sells fog juice and generators. At least around Halloween. Or a
party store or Spencer gifts.

Don't use ethylene glycol antifreeze; highly toxic! Non-toxic antifreeze
or glycerin.

Insect foggers (Home Depot, Lowes) make a mineral oil fog that is harmless
in low doses. Can also use fog juice in them.

Yup. Theatrical smoke machines. We use them for training in our fire
department, it's passably accurate smoke but tastes odd if you're in
there without your SCBA on.

I'd stick with the pre-mixed stuff they sell, myself.

I'm guessing liver damage and death since that's what happens if you drink
it.

They also make small squeeze bottles (kinda like the ones eye drops or
nasal spray comes in) with silica powder. I would imagine talc or
carpenters chalk would work, too.

Lots of other good suggestions have been posted

I wouldn't want to stay in a room full of the smoke but if your only
using a little propylene glycol smoke to see air currents It should be
too bad exposure wise. They use the same thing in wind tunnels because
the smoke is extremely visible.

Fog juice in an old iron would probably work well too.

If you have a soldering gun with a desoldering bulb on it, you could
fill the bulb with fog juice and drip a little on the tip and watch
the smoke path.

P.S. if you ever want to add smoke screen to your car inject
antifreeze into your exhaust manifold. It works great.

How about gathering some dandalion seeds or other very light objects?
Soap bubbles?

Ask one of the neighborhood kids if he has any smoke bombs or "snakes"
left over from 4th of July : )

Titanium chloride is the standard "non-toxic smoke" for air-flow tracing.
But you can home-make a chemical smoke that's nearly as dense, in one of two
ways:

1) Obtain some ammonium chloride powder or crystals. Heat a small pile of
the powder in a vessel with a small nozzle. DENSE clouds of ammonium
chloride aerosol will emerge as the powder sublimes.

2) Make an ammonium chloride generator. Equip a bottle with an air inlet,
an air outlet, and a hanger from which you can suspend a wad of cotton waste
about halfway up. Fill the bottle about 1/4 full of the most concentrated
household ammonia you can find. Wrap a stainless steel wire or plastic
string around a wad of cotton waste about the size of a ping pong ball.
Thoroughly saturate the ball with muratic acid, but not to the point of
dripping. Hang the ball just above the ammonia solution so it doesn't
touch, then close the jar and introduce a gentle air flow into the inlet.
Ammonium chloride aerosol will emerge from the nozzle.


The chemical process for TiCl is similar, but very expensive.

If you can't find ammonium chloride by name, look for sal ammoniac.
Same stuff. It's available in blocks for tinning soldering coppers.

Wow, I asked the right people.

Thanks
