Improvising a car fuse

From the RULES OF THUMB blog, whose RSS feed doesn't actually link to its items (?!), this interesting and potentially flammable tip: "If your car blows a weird-looking fuse and you don't have a spare–one wrap of cigarette-pack foil around the old fuse will give you a 20 amp emergency fuse; two wraps will give you about 35 amps.
