I was reading about palladium.
Me: “Palladium is a rare metal used mostly in catalytic converters.”
Vanessa: “What’s a catalytic converter for anyway?”
Me: “I’m not exactly sure.”
Vanessa: “Great…so when I go to the mechanic and they say they need to replace the catalytic converter, I can say, ‘I don’t know what that is, but did you know that catalytic converters use a rare metal called palladium?'”
