Old M-70 firecrackers

[displayfireworks1]

These came my way recently. While they are old , we see that they are fake. Plus an old Ozark Smoke.

Here is my unlisted video. We can see more firecracker trickery. I was suspicious when I saw M-70 on the red crackers. The old Ozark Smoke was pretty good. What type of composition was used in the old crackers? Opinions are welcome.

Ding ding ding! Yes, you're correct on the nitrate based flash. These weren't half bad due to the amount of confinement they had but there was a batch that had a really healthy dose of comp. and I believe is what got Apollo of the Ozarks in hot water. Indian market uses this "pseudo flash" in their Sutli crackers along with all the other crackers. Makes for quite a low-pitched whallop for sure. Thanks for sharing.

I've never seen the Cherry Salute M100s nor the Miller crackers before. Maybe a weird way to put an apparent use of left over cupsets or m80 tubes to use with small crackers? Even more strange to see paper fuse on a salute tube.

Would be neat to see a compilation vid of a few of those in action!

Apollo of the Ozarks had a patent on those M-70's with the disc and wax plug design. I had a bag of them back when. The manner of construction combined with what appeared to be close to double that of a Chinese cracker gave them a pretty good bang. Also available back then were similar size tubes, dark blue, called "Twitter Flitter" for evening use which spit out gold sparks with a sputter. I know that German Dark was used back then, from my experience with our local plant (late '70's-'80's). It would be interesting to perform a dissection on one of those M-100 cherry salutes to see the amount of the charge. They appear to be 1" cups, and not the 3/4" use in the original cherry bombs. Again, from prior experience, those 1" cup sets filled 2/3 with a good Vitamin F pack a hell of a wallop, without any coating, when glued and sealed tightly.

Here's Appolo's patent for the cracker Dave dissected:

Ah the good old days. It reminds me of being in middle school. The kids sold firecrackers and M80s during lunch. I spent every cent I had. Firecrackers: 3 packs for a dollar, M80s: 50 cents each.

Been a long painful death or our little noisemakers:
1906..........6" limit for rail transportation
1954..........1 1/2" length limit
1966..........2 grain limit
1977..........50 mg (0.77 grains) limit

and at the 1976 CPSC hearings, if it hadn't been for good old Missourian John Blogin to again point out that firecrackers serve religious purposes for people of Chinese descent, we would be like Canada and have no firecrackers at all. The measure to ban failed on a 3-2 vote.

How many milligrams is 2 grains..?

[gweilo]

2 grains would be around 130mg.
