Talk at NZ Skeptics 2010 Conference, Wellington

The talk I gave at the 2010 NZ Skeptics Conference is still online, archived on the Science Media Centre site. Thought it'd disappeared.
We introduced this afternoon talk by having three of us enter the darkened conference room and 'investigate' it with EMF meters, laser thermometers, and wearing head torches. (Denise and Mark helped me with this bit.)
"Are you picking up anything on that side of the room, Mark?"
"Well, I don't know about ghosts but there are an awful lots of skeptics around here."
It got a good laugh, which made going into the talk a bit easier.
It's not very interesting to listen to without the illustrations and slides, but some of it is at least a bit humorous. Many of the photos discussed are in our book 'Spooked...'
I found it somewhat intimidatiing to talk to an audience consisting largely of scientists and others with an average level of education similar to university lecturers. Humour had to be the way forward.
The talk, if you want to listen.
