Hiya, tis me again. We went to Malta this Summer, not least to get away from the weather. Here is a video explaining the piezoelectric theory. Hopefully it is easier to understand with someone talking about it:
Here is another which shows how the probes for the electrodes are placed and they are visible throughout as we had someone around to film it this time! The results are not as good as at Lligwy, but the dolmen was not in such great condition either.
