Help needed... spraycan for talcum powder Answered

Hi, I'm working on a project at the moment, and I'm trying to come up with an ingenious solution to spray talcum powder over a distance of 6 feet, or so... a bit like an aerosol spray. I've thought of a squeeze bottle (but that's a bit rubbish as you don't get any distance), or something like those modern water pistols fashioned out of a bicycle pump? Anyway, I'm stuck... Any help would be greatly appreciated.

What task are you trying to complete? I've sprayed a talcum dope suspended in ethanol - you can get a very long stream ;) But, you won't get a nice dispersion. Yes - ethanol.... 200 proof too (until you open the bottle and expose it to moisture :P) ;)

I'm trying to make a homemade pepper spray. What did you use to spray the ethanol?

Ahh- then this wouldn't be very good.... 1. Ethanol + eyes (or any mucous membrane) - not a good thing at all 2. It's done with an HVLP spray gun :P

duster these are used in gardening, basically just a hand spun squirrel blower with a hopper.

Oh yeah, I forgot to mention... it has to fit in your pocket! I liked the mini duster though...

Ha! I got all worked about this and made one, (It definitely doesn't fit in your pocket, though :P ). It's more of a thing you would use to dust the crowd during concert, kind of like that leafblower-powered toilet paper gun I saw. Strange, I can't find the MAKE link, but you get the idea.

6 feet? you would need an air blast 'cushion' around the blast. have you thought of using a smoke ring generator? that's probably your best bet to control the air stream without loosing it over distance.

You want something like a dry powder fire extinguisher? These tend to use carbon dioxide I think. You need to blow air (or other gas) into your talc' container, into the powder, and have the exit above. 6 feet is pushing it a bit. Also, why do you want to do this?

I'm thinking: Fan / Vaccum air intake hooked up to a tube, and one feeds powder in through the back.


I wonder if there are already commercial products (for parties, maybe?) that spray out powder/ confetti

A sandblaster?

I love these lines!

I swear that I've seen little leaf-blower like things with a hopper for dusting plants, etc. with pesticides.

You couldn't drop a hint as to what it's for, could you?
