A gas leak can happen indoors, and there are lots of reasons you wouldn’t be able to smell gas. For example, if your home is on a lot, like a farm or a ranch, there may be gaseous fumes coming from the soil, which you wouldn’t be able to smell.

Haha, no, definitely don’t do that, since that could result in serious harm.

If you smell gas fumes or your smoke detector goes off, it may be time to call a professional.
