I've been doing some research, and it seems that these Cybermen are also vulnerable to a chemical mixture known as the Cocktail Polly. Can someone with more experience with these creatures verify this?
If this is true, the components are easy enough to find, and I can create find containers for them that would keep them stable until they need to be used, whether it be in fire extinguishers again, or as some sort of projectile. Hopefully it can be an additional weapon that can be used to protect ourselves.
