I'm feeling great and have been a total menace this week (hexbear.net)

Yeah, no drinking just high on life but goddamn this is shit that I wish I did when I was drunk. I have been a complete fucking menace to the asshole drivers I deal with as a pedestrian this week. I live in a very car dependant area, and very frequently get verbally harassed or almost ran over. Normally I just shrug it off because I just don't want to care, but now it's like I have to react. In the first kitchen I ever worked at, there was a game of just throwing shit. It was a competition to see who could throw the most accurate throw. The best one was a line cook threw a fry into my shirt pocket from 30 feet away while I wasn't even paying attention. So I've been training how to throw quickly and accurately like my ability to slack at work depended on it.

Was walking to the convenience store the other day for some pouches and someone called me the f slur. At the exact same time, I found a block of wood that had been littered onto the sidewalk, so I threw it at their back window. Yesterday, an asshole was honking and screaming for someone in front of her to turn on a red while I was trying to cross. So I threw a few fries from the dinner I was bringing home into her window. What does this achieve? Nothing really, but it feels really good to throw things at assholes. Today some asshole in a BMW almost hit me while I was crossing the street, and I seriously regret having nothing good to throw.

I don't think they have to be used, it's not an electrical thing according to the ninja rocks article on NATOpedia

Tempered glass, which is used for the side windows of most vehicles, is manufactured with an extremely high surface compressive stress and high internal tensile stress. This gives it strength and durability against shocks and blunt impact. When the glass breaks (such as in a serious vehicular collision) the internal stresses present in the pane cause the entire pane to shatter into thousands of tiny pieces. This reduces the risk of laceration one might otherwise face when using 'normal' glass, and is an essential safety feature in vehicular design.

It is these physical stresses designed into tempered glass which make it vulnerable to ninja rocks. Made of shards of aluminium oxide ceramic, ninja rocks are very hard, and very sharp. When thrown at tempered glass, the ninja rocks' sharp, hard point focuses impact energy into an incredibly small area without blunting. This disrupts the glass surface compressive stress at the point of impact, subsequently releasing the internal potential energy within the stressed pane, shattering the glass.

To be effective, a ninja rock needs to be sufficiently sharp, impact the glass on that sharp point, and impact it with sufficient force. Thrown ninja rocks may often fail to shatter tempered glass if one of these conditions is not met. Ninja rocks are ineffective against windshields, as these are made of a laminated type of safety glass, and designed not to shatter.
