Is making it illegal in WA? Can I make it but not use it? Is there a special place/location where it must be used? These are all questions that have baffled me for a while now.
Yes, it is illegal. See State v. K.E., Respondent (1999), who created gasoline-styrofoam napalm, and was convicted of violating RCW 9.40.120 (possession, manufacture of disposition of an incendiary device). That is defined as "any material, substance, device, or combination thereof which is capable of supplying the initial ignition and/or fuel for a fire and is designed to be used as an instrument of wilful destruction". The law is framed in terms of the what use underlies the design of the substance, not the individual's personal intent behind possessing or making the substance (defendant's actual use was to light paper in a fireplace).
