well, the engines or planes usually don't explode, they catch fire and critically fail. But in the time it takes for the foam to congeal or harden most of it would already be whicked away by fast moving parts before hand, that's not to say all those millions of particles wouldn't be bad for any intake system though.

[Vass654]

What if it was cut with a strong adhesive?

Also, I was figuring on this mostly being used on military or hard security targets, people who would/should be in harnesses or strapped in. An airplane should be able to make a glide, and a rotorcraft should be able to autorotate to safely-ish land. It's not no risk, but much less than if you opened it like a tin can using an autocannon.

Also, figure points for style. Taking down a million plus nuyen aircraft using 50 nuyen plus launcher, and since the 2.5m ball was per dosage... Couldn't one up the dosage quite a bit and create even larger balls of lovely foam?

Hell, you could use it to knock out their eyes and ears. Target sensors and antenna. Target their guns.

As for a dragon... Huh. Use a massive enough dose, and launch it down their gullet?

New spell idea :choke dragon.

Something tells me, it's threads like these that keep the alien invaders away.

[Vass654]

Oh, remembered this one from when I was first looking at the foam.

What if you use it as a cheap armor filling? If it doesn't increase weight or expand as it sets, couldn't you spray it between body panels or in open spaces (like within a wing structure) of a vehicle/drone to give it some (extra) form of armoring?

[Shaidar]

This stuff is basically a Military Grade A/B foam or the can of spray in insulation foam you can by at the hardware store IRL today.

It expands like mad to fill all of the cracks and crevices.  I had a bit under a finger nail until I washed real good with a mild acid, and boy was it painful.

New use: torture device.  Spray under finger nails, then apply hefty amounts of tape to concentrate it's expansion under the nail.

Personally, I think Terra is under a galactic quarantine because we are so violent and are too dangerous to be allowed to spread beyond our own system.

Barrier Foam:  This hand-held canister comes with a built-in spray applicator.  The chemical inside it is a foam that expands on contact with air, then dries and hardens in seconds, creating a protective cover that can support heavy weapon mounts. One can contains enough foam to create a flat grey barrier one meter tall, one meter thick, and ten meters long; it does not build up well, but careful application of a new layer on top of a hardened layer will create a taller, if not structurally sound, wall. Barriers can be shaped, to a degree with the careful use of entrenching tools. Soldiers will often use tubes or boxes to create gun ports in the foam while it is being applied.
  When applied, barrier foam is soft until the end of the Combat Turn in which it was deployed, at which point it hardens into a rigid form with Armor Rating 14 and Structure Rating 8. If used in a chemical grenade, one application of barrier foam is enough to create a sphere just over 2.5 meters in diameter, or if triggered on the ground, a flat dome one meter tall and five meters across. Targets caught in liquid barrier foam have until it hardens to escape or risk ensnarement and/or suffocation.

This sounds like what is being described.



Which is is roughly 2 Gallons in volume, or 7.57082356 Liters, or 0.007570824 Cubic Meters.  Which expands to 10 Cubic Meters, or 1320 times it's original volume, in 3 seconds time.  Which is nowhere near fast enough to replace an automobile's airbag, which expands in 1/30th of a second and the deflates.

[Mithlas]

Yes, but an airbag (probably) won't kill you and has no-where near the same hardness as concrete. I still think it's ridiculous to think that we're ever going to get to a material that can, with only 3-5 seconds of curing, equal concrete.

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

...most engines aren't built to handle concrete forming in them, at the very least, it should freeze up any moving parts.

I seem to remember this exact use in several series, my favourite being Ghost in the Shell. I'm actually surprised that it wasn't mentioned as a possible use with the Freeze Foam in Arsenal. The concept is older than 3E.

That picture would make one heck of a big chemical grenade.

The canister version contains approximately 10 cu. m of foam, as you stated.

A chemical grenade, based on the diameter stated, contains approximately 8.18 cu. m of foam.

Most grenades are roughly the size of a soda can, so the canister - being only about 20% larger, is probably a lot smaller than the one in your picture.

It's probably more along the lines of those cans of expanding foam you can get at the hardware store.

[Red Canti]

You could probably use it to make a simple closet an inescapable cell. Or keep a Johnson from leaving a meet.
One situation may very well lead to the other.

I really wanna boobytrap a car with a bunch of these.
