I looked in the chem files. Iron seems better than Alluminum foam (slightly more durable, but still easly wrecked with bare hands). Personally, alluminum foam is a minor nuicance. At least it's not mutagen-foam! I am making myself an encyclopedia of REALLY nasty grenades and that seems... effective... but cruel. Blinding, deafening, clumsy-ing, Tourettes-ing, etc. is worse than killing in the eyes of admins right?
Oh, and foaming agent doesn't need water. It just works on iron or alluminum(1pacid+1agent+3iron/alluminum).
Flouresurfacent/Foam surfacent/Foam Precursor however DOES. It can deliver any chemical though! Acid/napalm bombs! Mutagen warheads! Antiviral/Spacecleaner Quarentine granades!
Speaking of Napalm, does it work? I tried making it in a beaker and it vanished. The components were gone, but no napalm AND no !!Chemist!!. I should really try it in a grenade. But with or without foam? And should I waste valuable grenades on something I don't know will work?
Oh, and Hyperzine seems to not do anything but cause side-effects. Why? I thought it would... I dunno... caust Toxin damage and give temporary Hulk?
EDIT: Spacelube is REALLY slippery. Even walking people go FLYING when they step on it. HALARIOUS!
