What is what are ninja rocks?

Ninja rocks are small, jagged pieces of ceramic that are often used by burglars to break car windows without making much noise. They are typically about the size of a small pebble and can be found in various colors, including black, white or gray. The term 'ninja rocks' comes from the fact that they are difficult to spot and silently break windows, making them perfect for stealthy operations. Ninja rocks are illegal to possess or use, as they are considered tools used for criminal activities. If you come across ninja rocks or suspect someone of using them, it's important to contact the authorities immediately.
