I mentioned an infant gas pup tent (as opposed to a gas mask) which is in the MoMA exhibit "Safe." [That tent has been replaced by a half-body gas hood get-up that allows you to change or feed a kid while he's wearing it.] Now Regine has rounded up several other gas masks in production right now around the world.
Trippy and unsettling, but I tell you this much, it beats slapping up some duct tape around the window frame.
