====[[#Fluorosurfactant|Foam]]====
When a foam reaction occurs, the foam will consume any other reagent in its original containers, and spread that reagent to flooring and people/mobs who enter its area of effect. The foam will spread slower than smoke and is usually slippery. Reagents will be copied through the [[#Vapor|vapor]] type delivery to those affected over the duration of the foam, BUT the reagents will be heavily diluted depending on the amount of foaming reagent used. Any clothing will reduce how much of the reagents will enter a person's bloodstream. Furthermore, foam reagent bloodstream insertion is divided into several 'ticks'. A minimum amount of reagent is required per tick for it to enter a bloodstream. So if too little reagents are contained in the reaction, or too much foam is used, the foam will do nothing. These ticks are counted ''after'' dilution and protection from clothing. On the other hand, if you use very small amounts of foam, the reagents may instead multiply in the bloodstream to more than the original amount. MODsuits with helmets on will make people immune to getting reagents into their bloodstream through foam. Despite dilution, the foam will still copy remaining chems such as [[#Fluorosulfuric Acid|acid]], [[#Chlorine Trifluoride|CLF3]], or [[#Space_Cleaner|Space Cleaner]] to any tile it touches (but not walls, windows or doors). Foam will not block sight. <br>

'''Foam example 1:''' 250u foam containing 10u [[#Cyanide|Cyanide]] will spread a blue foam that does nothing to those it touches. The poison is too diluted to work at all. <br>

'''Foam example 2:''' 20u foam containing 250u [[#Fluorosulfuric Acid|Fluorosulfuric Acid]]. A small area and everyone touched by the foam will have large amounts of acid slowly melting their clothing and the affected floor and items. Those who did not wear a MODsuit will also have a large amount of acid in their bloodstreams, depending on what they were wearing and how long they were in the foam. If they had internals on or not doesn't matter. <br>
