Four hours of clean smoke? Sounds like you got lucky man.

Three cheap ones on a single door? That sounds like you were going at it pretty hard. Maybe the problem isn't the screws, maybe it's the drill or the technique. I've hung plenty of steel doors with basic hardware store screws and never snapped one off unless I was rushing or using a bit that didn't fit right. People tend to blame the tool when the user is the real issue sometimes.

Basically napalm" is the perfect way to describe it, I am the proud owner of a blackened broccoli campfire myself. I swear my air fryer runs 50 degrees hotter than the dial says, which is great for frozen fries but terrible for anything that isn't basically a brick of meat. I just tell people my broccoli was extra crispy and hope they don't ask for a taste test.

Whoa, actually frost heave is from water freezing under the slab, not inside it.

Nothing like mom's 30 year old curtain wisdom to save the day.
