ABSTRACT:
Self-defense device has a charge of liquid, preferably substantially water so that, when the device is actuated, it is heated and expelled from a nozzle to be directed at an assailant. Heating of the water may also develop gas pressure which causes the expelling of the water, or heating may cause boiling to result in both pressurization and water expulsion. Black powder and cordite comprise mixtures which, when combusted, cause heating of the water and expelling of the water by separate gas generation. In other cases, a material can react with the liquid to cause expelling of hot liquid. An example of this is alkaline metal, such as sodium, being admixed with the water when expelling is desired.
