Well, the talk went ahead this morning, and worked quite well. It was a shame the audience numbered only about ten, but this *is* a small convention. (Other speakers had even smaller audiences...)

Anyway, I used a few props to make demonstrations - talcum powder for how the lunar surface would hold a print; blowing the powder at the audience to show how lunar dust doesn't behave; then pulling the belt off my pants to do a flag demonstration (no, my pants didn't fall down!). These all got a bit of a laugh, which was the main objective.

No one seemed to be a hoax believer, and a couple of people came up to me afterwards to say they enjoyed the talk. So thanks to all of you for your suggestions; they helped make the talk that little bit more interesting.

Incidentally, the speaker on after me mentioned that Harrison Schmitt is coming to Australia on some sort of speaking tour. Gee, I hope I get to hear him speak!
