    15:20 this is used as a technique in dirt track racing to help keep the tire cool. It is done to new tires, and it is not cut to deep.

    had a 1997 explorer sport, had to remove the ball hitch from its stock position, tried a wrench, nope, try a breaker bar, nope, tried a breaker bar with a jack handle for extension, the hitchs threads snapped, leverage is a hell of a thing, at the time i was shocked because to me that was a large "bolt" to break, but if i do the math for the length of the lever and force put in yeahhhh should have seen that coming

    For the alarm on your head hack I believe it works because our body’s conduct electricity ⚡️ and our brain 🧠 has most of it. It amplifies the signal like an antenna. 🧐
