The devices and methods described below provide for a plasticized, adhesive binary explosive mixture formed with nitromethane (NM) plasticized with nitrocellulose (NC) as an energetic component and a urethane resin mixed with any suitable mechanical sensitizer as the sensitizer component. The addition of the sensitizer component to the plasticized component of NM/NC causes the resulting gel mixture to become explosive while maintaining stability.
