   For weaponizing tungsten plasma, you already have the Casaba-Howitzer concept:   
   directing a nuclear explosion through a tungsten plate, which throws a plasma   
   cloud at high speed (as in, 3% of c). Only a few percent of the nuclear   
   explosion will probably    
   contribute to the energy of the plasma (the rest is wasted in destroying the   
   nuke itself and beaming all around), but a few percent of an enormous amount   
   is still pretty big.   
   Design it so it widens fast, and you can use it for nuclear external pulse   
   propulsion (a.k.a. Orion). Design it for a narrow cloud, and you have a plasma   
   thrower. The range is still pretty short (I wouldn't bet on more than one   
   kilometre), but it still    
   beats classical nukes hundreds of times.   
   It would be a space weapon, mind you. In atmosphere, it wouldn't make much   
   difference compared to a classical nuke (plasma would be stopped by air, and   
   the shockwave would be more destructive than anything else anyway).   
      
   Now, about putting the plasma cloud in a handwavium bubble. Basically, you are   
   freezing a nuclear explosion and throwing it at the face of your target so it   
   can burst there.   
   Many find it stupid, but I think that's fine as far as 24-carat handwavium   
   goes, though you have to keep in mind those questions - without creating even   
   more unanswered questions:   
   - If they have a strong enough bubble so it can freeze nuclear explosions, why   
   can't it be used in other applications - like a forcefield defence against   
   said explosion?   
   - Why don't the other side burst it by throwing sand clouds at it?   
   - How the hell does it get past air in atmosphere?   
   - Why don't they directly throw a a CH to explode at/near impact instead of a   
   fiddly bubble?   
   - At this tech level, why don't they have more efficient weapons anyway, like   
   lasers, particle beams, relativistic projectiles, grasers, micro-black-hole   
   launchers?   
      
   What I would suggest, for example:   
   - The handwavium bubble is derived from (and powered by) the explosion itself.   
   So it can only be generated by detonating a nuke. Also, it keeps plasma in,   
   not out.   
   - The bubble fails after being depleted, not being burst like a balloon.   
   Small, fast projectiles will go through it and take away a tiny bit of energy   
   (so it will slightly decrease its range) but only being out of range, or   
   impacting a massive object (   
   depleting all its energy instantly), will burst it.   
   - Air depletes its energy fast, so its range is extremely limited there - it's   
   more of an extended flamethrower, particularly with the intense beam of fire   
   it leaves behind it. Only for very well-protected weapon platforms, or they   
   will fry themselves    
   firing it in air.   
   - The bubble is harder to intercept than a solid object, as high-speed   
   projectiles will go through it   
   - They didn't invent it - they reverse-engineered the stuff of a previous,   
   long-extinct civ. In fact, they have no idea how it really works, and it was   
   probably never used as a weapon as they did have some way more efficient stuff   
   - so it's like cavemen    
   sticking a butcher knife at the end of a rifle. Not the original use, but   
   still better than a stone axe. Bonus: they can have as much/little handwavium   
   as you want, and an unlimited access to Raiders of the McGuffin plotlines.

   vacuum and atmosphere.

   0.5cmx50cm cylinder.
