Falcon, probably the same idea but not the same design. The ones I remember were spherical, and as I said, about the size of a large pea. They were made of something like paper mache, and I know from opening some, there was tiny gravel and a powder inside. I guess it could have been silver fulminate, but I don’t know. They came in little cellophane bags, maybe a dozen per bag, and in different colors. I think they were about a dime a bag in the 1950s. They may still be around, but as I haven’t bought any fireworks for many years, I don’t know. They were pretty easy to set off, and you could throw them on a sidewalk or step on them (or shoot them with a slingshot, which was my preferred use).
The noise mines, however they were designated, were undoubtedly of similar construction - but probably a lot more expensive than a penny each.
I somewhere have an original copy of Tenny Davis’ 1940’s book, “Chemistry of Powder and Explosives.” It contains (among other things) a huge amount of information about fireworks of all kinds, and I’ll see if I can find the book and look up what it says about these, if anything. By the way, a valuable resource, even though much technology has changed since it was written. It has extensive information about anything that goes bang, including primer compositions, black powder, smokeless powder, and all types of explosives.
