So less tannerite  next time?
And shoot from a little farther away

It is much more powerful to seek Truth for one's self.  Seeing and hearing that others seem to have found it can be a motivation.  With me, I was drawn because of much error and bad judgment on my part. Confronting one's own errors and bad judgment is a very life altering situation.  Confronting the errors and bad judgment of others is usually hypocrisy.

Tannerite is a neat toy but I'm kind of surprised it hasn't been banned. Too many morons doing stupid *expletive deleted*it with it. A couple of years ago some dipshit packed and old stove full of it and managed to kill his daughter when it blew up.

I know it's not considered "manly" to read the instructions (or to follow them), but sometimes it's a good idea.

Some jackwad in the midwest set off 100 pounds of Tannerite and ended up facing a ton of charges, including felonies, because he tripped the threat monitoring equipment at a nuke plant nearby.

So do all who live to see such times. But that is not for them to decide. All we have to decide is what to do with the time that is given to us. There are other forces at work in this world, Frodo, besides the will of evil. Bilbo was meant to find the Ring. In which case, you also were meant to have it. And that is an encouraging thought

They used to use a lot of tannerite on the "Sons of Guns" TV show . . . sometimes in what appeared to be rather large quantities. IIRC, they sometimes "enhanced" the effect with gasoline, kerosene, or some other flammable liquid, and had to call the local fire department at least once.

They had various licenses so maybe they could legally do stuff most of us can't . . . not to say they were smart about it. I remember one show where they took a demilitarized 20mm cannon, welded it back together, and shot it.  :facepalm:

Of course, once the owner was charged with child abuse, the show went away.

I guess they used three pounds, but somewhere I thought I read 24 lb.

Bad luck that a fragment flew right at him.  Figuring a 30,000 psi* overpressure pushing large chunks of metal around, they must have been moving pretty fast.

Anyhow, you're not supposed to mix more than ten pounds in place (no transportation) except for theatrical or entertainment purposes or something like that. I wonder if that concept can be stretched to some of the huge amounts I have heard about on youtoob.  That clip in the news video showing the barn blowing up used >160 lb, if I recall correctly.

https://www.youtube.com/watch?v=edRbcTXAijY&feature=player_embedded

(Found it, added URL for documentation purposes.)

Ten lb sounds like a reasonable amount for stump blowing and tree cutting and other practical uses.

Hey, I ain't sayin' it ain't fun.  In 99% of the videos, the folks laugh like hell.

A single pound will do a tree stump just fine. No need to get crazy.

Dad has some for play time. It both concerns and amuses me. So far, I have not taken it away from him. That could change.

Oh, I didn't mean to imply that stump removal needed ten pounds, just that that was a good amount to have for practical purposes.  (And for funsies.)  Don't know if that's the limit on what you can have, or what you can mix at one time, or what.  (I saw a BATFE sheet on binary 'splosives once, so I'm just working from memory.)

If someone can come up with exact citations, that would be nice and might keep some folks out of trouble.

Me, I don't mess with "fast chemistry" any more.  I've still got ten fingers, two eyes, one head, and two shinbones.

Unlike our friend in the article.

But I am a little deaf now.  >:D  :rofl:

As a kid I did plenty enough damage with the powder taken from a 1,000 pack of Black Cat firecrackers, a medicine bottle and a roll of electrical tape. I set it off on top of dad's utility trailer. Dad was "impressed" with the damage to the to the 2x4 it was sitting on and impressed upon me his take on my deed.

My dream involves a lot of tannerite, an abandoned building, about 500 lbs of coffee creamer and aluminum powder siting on top the tannerite and a rifle that can get there from another post code.  >:D

Yup, deflagration speed is *definitely* a thing.

You'd be surprised how many people don't seem to understand that.

It's been noted that BP burning speed in a barrel goes up as the granule size goes down --FG to FFFFG.  Smaller than that, as in an actual fine-grained dust, the burning speed goes down since there isn't room between the powder-like grains for a flame front to penetrate.

I have found that my tiny 1/4" bore 1.5" barrel model cannon* makes a pretty good "pop" with FFFFG even with no wadding whatsoever.

For very large naval cannons, in 1875 Dupont finally came up with "Hexagonal" powder for large artillery, which was pressed using shaped molds with small center posts, the resulting "powder" grains being about 1.5 inch in diameter, rather like a large threaded nut without the threads. The center hole widened as the grain burned. By 1880 naval guns were using Hexagonal "powder" 1 inch in height.  They no longer called it powder, but simply "Hexagonal" as a trade name, like "Kleenex" is used today. This has been called the ultimate development of black powder.
