1. Deep-Water Drilling
I used a 3-inch drywall screw to hang a heavy, framed painting in my bedroom, because the extra length provides more load-bearing strength, right? It held the frame fine, but two months later, the living-room ceiling collapsed. Turns out the screw had punctured a water pipe, creating a slow, insidious leak.

Lesson Learned: Use a hollow-wall anchor, not a drywall screw, which can plunge deep enough to do real damage.

2. What a Tool
I rolled the drum floor sander into the room, plugged it in-and it took off like a crazed robot. I gave chase as it bashed a hole in the wall and raced into the next room.

Lessons Learned: (1) Make sure the machine is switched off before you plug it in. (2) If you forget the first lesson, never chase a runaway floor ­sander: Instead, pull the plug.
