What is ninja rocks?

Ninja rocks are small, unassuming pieces of broken ceramic spark plug insulators that are often used as improvised tools for breaking into cars. These rocks are often found on the ground near parking lots or in other areas where cars are parked. When thrown at a car window, the sharp edges of the ninja rock can easily shatter the glass, allowing thieves to quickly gain access to the vehicle.

Ninja rocks are also known as car thieves' best friend, as they are cheap, readily available, and highly effective at breaking car windows. This makes them a popular tool for smash-and-grab burglaries, where thieves target parked cars to quickly steal valuables left inside.

The use of ninja rocks is illegal and can result in criminal charges for the individuals caught using them to break into cars. Car owners are advised to be vigilant and take precautionary measures to protect their vehicles from potential break-ins, such as parking in well-lit areas, keeping valuables out of sight, and using security devices like car alarms and steering wheel locks.
