As I was taught in the Army, when you pull the pin, Mr. Grenade is no longer your friend.

1. Grampa Had A Live Grenade

Well, that's just foolish.

2. I thought the same thing.

How? When? Why?

I have questions.

3. As To Your OP Lesson...

...in the military, yes a grenade nearby is nobody's friend.
I fear too many people think it's just a big firecracker.
But, higher density means more mass for its size, a 40% higher energy per unit mass, and about 9x the velocity.
The pressure wave & gas volume at that velocity leads to 12-13 times the pressure. One is eardrum damage, the other is dead.

4. I always enjoy your explanations

I learn something every time!

5. WW2 vet probably?

They brought back all types of stuff after the war. I know a guy who's grandfather brought back a bunch of captured nazi machine guns. Has capture papers for all of them. That collection is worth a small fortune now. Just 2 of the guns are worth 50k each.

That said, for the grenade. Yea, they definitely got brought back even though they weren't supposed to. Guns could be brought back easily enough for the most part. Explosives not so much. But they are small enough that they could be easily smuggled back. It's not like they checked every single bag and crate on the way back home. Finding grenades while cleaning out a vets attic or basement isn't very common, but it's hardly rare.

8. If it was a WW2 era grenade

It was probably made with TNT as the explosive fill. That can get very unstable over time. That’s why we put a service date on munitions, and why we store them under controlled conditions.

12. Yep, I'm wondering if pulling.the pin was enough shock to detonate it

I'm sure you know that pulling a pin isn't as easy as they show in the movies. It takes a bit of yank to do it. Pretty much everyone doing it would be holding it with the spoon down, so unless they were dumb enough to let it go and fly(which is not out of the realm of possibility considering they were messing with a grenade) then the shock of yanking the pin might have been enough to detonate it if the tnt filler was unstable enough.

13. Oh, I used to do it with my teeth...

Like Vic Morrow in "Combat". Maybe that's why I use a tooth brush????

[DetroitLegalBeagle]

14. Lol

I tried it once with a inert trainer and nope, felt like a great way to mess up my teeth lol.

6. Sounds like a country song. The MAGA version.

7. Goddamit, Gramps.

You fucked up huge.

9. Last August the police found a mortar round?

And didn’t search the hell out of that property? And they didn’t wonder what else this old crackpot might have had?

Negligence?

10. Found on a property

Not that property. Sounds like a different house.

11. That's a hell of an inheritance to leave...
