Wouldn't steel wool catch fire when exposed to an electric current? It might be useful to indicate there was still some charge in the capacitors, though

That was my worry. The resistance might be too high and get too heated. The nail avoids that issue.

In a power supply, you'd also have to worry about shorting and shocking other ICs with steel wool, but not with a big capacitor.
