WD-40 is highly flammable!
Flammable, but not "highly"

Go read the label, you know the one that has the word DANGER on the
front in large type, and the word flammable right next to it?

The MSDS lists it as level 4 (severe fire hazard)

The label says "flammable" not "highly flammable", right?

Actually I have a can right here. It's not "highly" flammable.

It's EXTREMELY FLAMMABLE (all in caps)

As if it wasn't flammable enough, the propellent is propane.

Here's the more detailed warning on the back of the can:

Extremely Flammable. Keep Spray Away from: Heat, Sparks, Open Flame,
heated surfaces, and any other sources of ignition.

Disconnect electrical tools and appliances before spraying. Keep can
away from electrical source or battery terminals.

All I'm saying is what I know from experience--

I have a potato cannon. I use an explosive propellant. You spray it
in, hit the sparker, and BOOM a potato goes flying a couple of hundred
yards. It is much more explosive than WD-40 (or else I would use
that).

It is hairspray.

If you think WD-40 is explosive, you'd better seek a ban on hairspray.

You know of a spudgun fuel *less* explosive than hairspray (actually,
the
butane propellant)? I can't get my cannon to fire without vaporizing
the
potato.

Usually it is just 3 short bursts for a shot. A burst being just
enought get a spray -- maybe 1/4 seconds each.

You're sliding the potatos in like a muzzleloader, aren't you?

Well, yeah. Isn't compression a necessary part of the equation?

BTW, Dixie cups make perfect blanks for a 2" PVC barrel. Sometimes,
you just want to make noise to raise the dead.

I don't really compress it. I slide it in first. It does create one
heck of a seal, though. But I've never made french fries with it.
The spud goes out in one piece. I got "the long way" on the potato so
it's a good, solid hunk of flying flesh.

Compression's easy. Taper the inside end of the barrel slightly with
a piece of 100 grit sandpaper, so it punches out the spud
correspondingly
oversize.

I've often thought about putting some sort of groove in the barrel so
I can get some rotation on it. they it would REALLY fly.

Range would be the same, accuracy would be better.

I've seen rifled PVC barrels sold online for just this purpose. Not
cheap, though. I wonder if you couldn't glue in a loose spiral-wound
piece of wire pulled from a bit of Romex for the same effect. Hope
it stays in after the third shot ;-)

Could you cut fins from cardboard and install them into the spud
at a slight helical pitch to add spin?
