Propellant in a spray can canidate: Medi-First 'Cold Spray'

[Joshatdot]

I am tempted to find this localy, or order one from Amazon just to see how it compares to Starting Fluid w/hair spray nozzle.

Topical skin refrigerant, cools skin on contact. Use like ice for minor pain and swelling from sprains, bruising contusions and minor sports injuries. Contains Isobutane, N-Butane, Propane. 4 oz aerosol can.

Nice find! That's basically refrigerant in a spray can. The liquid in the can won't even need to evaporate, since it is essentially propane.

Holding the can upside down might allow just the gas to come out.

A lot of aerosol products have combustible gases in them: propane, butane, etc. However most products are not intentionally meant for combustion. (duh?) Air fresheners (poor, but works. surprisingly), body sprays (noxious if you ask me, but by any measure AXE worked well.), but by far starting fluid works the best (cheap, available, and not diluted as far as combustive fuels are concerned).

So if your not being a cheap ass using up all the aerosol products around your house first, rather buying aerosol products for the purpose of a spray-n-pray combustion, I'd suggest buying starting fluid.

I just cannot see how this product would not be diluted. How I made a simple point this long, beyond me...

Different manufacturer, but still.

While starting fluid is designed to burn, there is a liquid component that must be vaporized. Once that occurs, it is a matter of the burn rate and temperature of the individual gas mixes. Also, Wikipedia says that starter fluid uses CO2 as a propellant gas, which would theoretically displace oxygen (air) in the chamber.

even with the CO2, it still makes for one heck of a propellant!

...there is a liquid component that must be vaporized.

To make the liquid more atomized, I found out that a Right Guard spray cap fits perfectly over the nipple of the starter fluid can

I second that.

Happy New Year to all ye inebriated folk! I knoweth that I hath participated too much in this New Years Celebration. Shoudn't be posting this post, but am, anyways. HAPPY NEW YEAR!



P.S. Check out the ME 1-05H Page. Video plus High speed video (210 fps, I think). It's pretty cool.

I'm guessing they are talking about vaporizing, not explosive? Correct me if I am wrong on this point.

Further the ingredients,
Butane (40-45%)
Isopentane (35-40%)
Tetrafluoroethane (15-20%)
Isopropyl Alcohol (<2%)

Tetrafluoroethane - Flash point= Non-flammable

And the biggest point of all, my spray-n-pray experiences are very much along the cut-n-try method. I've shot a good variety of aerosol products, and I can assure you starting fluid works the best IMO. Hard to beat the price.

Knew my time was doomed responding to the old "NEW COMBUSTIBLE FUEL!!!" thread...
