Huh, never considered the splint trick, works brilliantly as a cover story for having the stuff as well if you tuck the applicator in a medkit.

Of course, the weight issue is still a thing, after rechecking War!, barrier foam canisters are indeed handheld, and can create 10000000 cubic centimeters of barrier foam. to put that in perspective, a cubic centimeter of air weighs about 1.2 grams, 10 million times that is 12000 kilograms, so unless barrier foam weighs less than air, that handheld canister is impossible to lift.

Think of a canister being like a can of shaving cream. It weighs less than 1 kg and the resulting foam fills a reasonably large size and is mostly air that shouldn't be part of your calculation of total mass. Think of barrier foam as being similar to polystyrene.

I understand the concept, but the scale make it unlikely. If we assume the canister somehow weighs 1kg, then when divided by the area it will cover, each cubic centimeter with get 0.001 gram of the substance, even if it is massively mixed with air, that's still only 0.001 gram of compound per centimeter cubed, which somehow manages to act as a solid structure (AV14, S8, if I recall correctly) If this was the case then it would revolutionize every aspect of science that can benefit from lightweight materials, which is almost all of them, and while advanced, the technology displayed in shadowrun does not display that level of advancement.

So I am forced to conclude, that it is silly, and that I should stop looking in to game mechanics to this degree, it only ever ends in silly buisness.

Also doubles as an enhanced termination system!

I kinda prefer freezefoam for some of these. ::)
I have R6 freeze foam in a splash grenade - works wonders and only costs like 44 nuyen. For another 50 you can make it gecko grip.

Well, yes.  I suppose the world would be revolutionized by such a compound; at least for a couple of hours until the foam degraded into a puddle of useless mush.

Only if you badly undercost the grenades... SR3 used 10x dosage costs for chem grenades someone else related after I suggested 20x was probably a good baseline.   SR4 only says chemical.. it does not say only a single dose of the chemical and given the huge area of effect even 10x is lowballing.

At 10x that you end up with a far more reasonable 260 per grenade.  20x... 500 per.


It seems rather silly that you end up with something better than a vehicular ares glop cannon just by packing an underbarrel GL.


Chemtech in War adds Barrier foam cannisters...
One cannister is enough to produce 10 m3 (cubic meters).   a 5m radius hemispherical splash... is more like 125 m3... and one cannister is far larger than a mini-grenade.

If used in a chemical grenade one application is enough to create a sphere just over 2.5m in diameter.  If triggered on the ground... 5m diameter and 1m high dome of freeze foam...


btw: love the good news suppository joke on that one...


But my other idea was the freeze foam ball...   use the 2.5m sphere... drop it from high altitude set it off... for the old looney toons dropping anvils effects.

have it programmed similar to nanosmokes to get anvils that form in mid air.

Sorry to kind of necro this, but I had a thought about barrier foam as an AA weapon or really, an anti-vehicle weapon.

Airburst a grenade in the intake of a helo or other aircraft. Pretty sure most engines aren't built to handle concrete forming in them, at the very least, it should freeze up any moving parts. Do the same to the intakes/exhausts of an armored vehicle.

Seems like it should be a pretty cheap, effective way to bring almost anything down, with a lot less risk of killing the people inside.

I like it. Wonder what it would do to a dragon.

You think people wouldn't die in a aircraft crash?
Remember, you don't have to kill the vehicle to stop it, just kill the guy driving it.

He did say less risk of killing the occupants, not no risk. If the engine stalls (which is what would happen if the air intake was clogged), you can generally attempt to make an emergency landing of some sort. Engine blows up (as with a grenade) you're pretty well fragged.
