|There is a very sensitive instrument that is used in the field. Each time you drive this tool into the earth you have
a certain feeling of tactility. You are very sure if you find glass, which is very slick. You start to get a sense for
the materials in the ground. Actually, you think about the mines, and then you don't think at all.
||The best feeling for me is if I know I sold enough excavated earth during my "sale" performances. Then I enter another
part of myself. I'm then totally happy as I count each German Mark, and I think how many square meters we will be able to
clean with this money.
