Gum Guns are weapons used by the Six Gum Gang in Operation: R.O.B.B.E.R.S.. It is a hand revolver made from a soda bottle that shoots wads of chewed gum at their intended target, most of the time going into people's hair. The middle of the bottle breaches out to one side revealing a revolving chamber, which holds up to six pieces of chewed gum at a time.
