Tonight I saw the 1944 movie “Double Indemnity”,

which is about a 保険金殺人事件.

 

https://www.youtube.com/watch?v=ele8v_7tuH0

is the very last scene, in which the insurance salesman Neff

(Frederick MacMurray) confesses his insurance-scam murder

to the insurance investigator Keyes (Edward G. Robinson). 

As he lies injured from a bullet wound, Neff gets Keyes to

light Neff’s cigarette.  But Keyes does it in a most unusual way:

 he seems to light an ordinary wooden match by flipping its tip

with a flick of his thumbnail.  This occurs at 1:35 in this clip.

 How is this magic trick performed?

Did matches in 1944 have the property of igniting when friction

is applied to the matchhead?  Sounds kind of unsafe.

 

Earlier in the movie is a scene in which Keyes is buying cigars and

has Neff light Keyes’s cigar with Neff’s cigarette lighter.

Neff says something like, “You know, when you buy cigars,

they’ll give you matches if you just ask for them.”  Keyes replies,

saying something like, “But they always go off in my pocket.”

(Wish I remembered the exact wording.)

 

The custom of breathing tobacco smoke, which occurs as

a matter of course in this movie, will itself be as much

a thing of the past as the centuries-past custom of

sniffing shredded tobacco into one’s nostrils is now.

I think I have seen this magic trick done before. If I recall correctly, it is done by gluing a little patch of sandpaper to the thumb, and lighting the match by rubbing the sandpaper across the tip of the match.

 

I have heard of people that can supposedly use only the fingernail of their thumb to generate enough friction to light a match, but that seems a bit doubtful and unlikely. At any rate, it would probably take considerable practice to succeed consistently. The sandpaper on the thumb trick makes it easy for anyone to do it.

Well, all matches have this property, even now. Sure, most matchbooks and matchboxes have a little strip of rough paper, like sandpaper, that makes it easy to strike the matches. But the “strike anywhere” safety matches with a distinctive red bulb and white tip are made so that they can be more easily struck on rough materials like rocks or concrete or such.

 

But no matter where you do it, friction is needed to strike them.

 

Not sure what is so unsafe about friction needed to strike matches, and I don’t even really know why those matches are called “safety matches.”

     Good movie, in which the always "nice guy" Fred MacMurray plays a real snook.

     This must have been a "kitchen match", which I just learned was invented (and patented" by Louis V. Aronson in 1903 [ en.wikipedia.org/wiki/Louis_Vincent_Aronson ].  Also called "strike anywhere" matches, these could be lit by running the head quickly along your jeans pants leg, or (with practice) by picking at the head with a thumbnail, both of which actions can produce sufficient friction for ignition to occur.  The trick was to avoid getting any of the incendiary material to crumble off under the thumbnail, as that would lead to very unpleasant sequellae.  Aronson's innovation was to put the friction-ignitable material only in the whitish half of the head, which cut down on accidental ignition through incidental contact with other objects in one's pocket.
     These kitchen matches were standard equipment when I was in high school, and smoking tobacco and other combustibles was in fashion.  They came in slide-out boxes about 1.5" x 3" x 5", but could be carried in a pocket for convenience.

     The striking strip on matchbooks contains a chemical that combines with other ingredients in the heads of matchbook matches to produce ignition, which is why matchbook matches will only light from another ignition source or by striking against the matchbook striking strip.

**** Encouraged by the photograph, I rooted around in a kitchen drawer and found that we also have a “diamond” brand box of “Strike On Box Matches” (I would hyphenate it as “Strike-on-Box Matches”).  Other wording on the box:

“greenlight” (the matches have a green head), Lights Quickly & Easily, 300 LARGE KITCHES MATCHES, Made in USA Since 1881, Includes wood from responsibly managed forests [Ooh, I feel so warm and fuzzy!]

CAUTION: CLOSE BOX BEFORE STRIKING, KEEP AWAY FROM CHILDREN

In smaller type:

The match tip in this product contains perchlorate materials. Special handling may apply in California.  See

www.dtsc.ca.gov/hazardouswaste/perchlorate

Two long sides of the box have a surface of what looks like millimeter-wide round bumps (maybe a twentieth as high as their diameter?) against which the matches are to be struck.

 

Naruhodo.

Yes, and that old trick of flicking the end of the match with your fingernail was quite standard. Unfortunately, occasionally a piece of the phosphorus would get under your fingernail and give you a significant burn.

 

There was even a problem with a metal container for matches that boy scouts carried. It had a screw top that allowed you to turn the cylinder containing perhaps a dozen matches to retrieve one or more. If you inserted the matches with the heads outward, turning this metal cover could set them off in a large flare-up.

 

There is also a very sad aspect of the history of the so-called safety match. The women who worked in the factories developed very serious health problems.

 

There is a book written about phosphorous that I think you would enjoy:

Emsley, John (2000). The Shocking History of Phosphorus. Unfortunately, I do not find this book in either the UB library or the Buffalo Public Library; it is, however, available from Amazon for just a few bucks.

Emsley also co-authored a more technical book about phosphorus many years earlier. Gerry
