Britain doesn’t use commas for decimal points, that’s a mainland European thing.

Cars have (or had, I don’t know if they’re still included) an electric lighter that you pushed in to heat up. It was basically a little metal ring that got really hot. So I think it probably is the heat.

I remember my friend also had a plasma lighter, that unsurprisingly used plasma to light things. It made a really scary noise in the wind and hurt like a motherfucker to touch. We were 18 and dumb.
