Try adding that to the dictionary, Mr. Spart. I definitely think its flamier.


I think you would stump a Spelling Bee with that one!!


I think I'd rather give you all time to forget it and then ask what it means on this thread.

Wars were fought with black powder for centuries. When a new, more powerful, but less stable explosive was discovered, inventors tried to find a way to weaponize it.

How were the dynamite guns of the 1890s different from other artillery?

Were the projectiles lite before launching them ?

No, not that I know of.

Clue- the projectiles resembled darts, or sky rockets with tailfins.

The naval versions had some holes with salt plugs in them. If they landed in the water, the salt dissolved , and the shell started to sink. The influx of salt water closed the electrical circuit, detonating the shell. If it was close enough to a ship the explosion would stave in some planks below sea level, and the ship would sink, much as if it had been torpedoed. A direct hit to the superstructure was less likely to sink a ship.

Additional clue- The question was about how the gun was different.

Yes - me and my not really reading the question.

How were the guns different.

Dynamite is ignited to set it off - so were the guns a sort of catapult so that there was no explosion to launch the dynamite - though this would only be good in close quarters combat .

But you said - If it was close enough to a ship the explosion would stave in some planks below sea level - so perhaps close quarters combat it was..

Spart, you are close enough, and I have to get ready to travel.

The dynamite was in the shell, not the propellant, as you have correctly surmised. But because dynamite can explode if handled too roughly, they used compressed air to launch it. This reduced pressure and allowed for lighter construction.

Torpedoes only had a range of 800 yards max at the time, much less for a moving target, so the dynamite gun was a superior alternative.

So dynamite guns were air guns. Then cordite was discovered and made them obsolete.

Your turn, Spart.

My question - where was the 1974 World's Fair held ?

A Clue then - the other side of that same State that the 1974 World's Fair was held got toasted May 18, 1980.

I took a peek and saw the answer. I have been to the site of the 1974 World's Fair. They have an awesome Carosel there now. There are some waterfalls at the site too.

Good guess - it had a World's fair - but 73 years earlier.

Buffalo, New York, United States, from May 1 through November 2, 1901



Cheat away.
