The device essentially functions as a liquefied petroleum gas flamethrower.” The inventor claims it is unlikely to kill but would “definitely blind” the assailant.

Patent Date: 1986

In this connection, it is well known in the art and practice of self-administered positive reinforcement activity that various techniques can be successfully employed to extol the virtues of one’s actions and thoughts. For example, it has been reported that many wealthy and successful individuals engage in conversations with themselves, that is, they talk to themselves. Such an activity is understandable in view of the often small populace of self-motivated individuals and in view of the large volume of self-defeatist conversation known to emanate from those of low self esteem.”
