Charles, an excellent use of SL. What I particularly liked was that I failed to extinguish the fires and received instant feedback but I couldn't quite work out what I was doing wrong (I was not moving the extinguisher over the base of the fires). I had to work that out for myself rather than receive further instruction and that enhances learning. Unfortunately my hands got burned so I now need instruction on how to deal with that (hand under running tap etc but the soothing kiss of a good woman might be difficult to replicate even for SL!).
Great job with the demonstration and thanks for the explanation screenrs.
