Questions

Do you know why some metals (like stainless steel for instance, and gold) make sparks in a microwave oven, and others (like some aluminium) don't? I've had many people give me a range of totally unsatisfactory answers (ranging from: "it's the shape of the objects" to "it's because aluminium is a better conductor than stainless steel" (what about gold then?)).

If you have an answer to this, and you know you're correct I'd like to hear from you. Mail me here. Note that there are NO prizes for correct answers, I'm just curious. I'll post the answers which I'm most inclined to believe here once I've received a few. Thanks
