    Going back into the past with a pneumatic hammer. Today the researches are getting down to the bottom of climate change and theyre doing so with the help of the sediments deposited on the sea bed over the course of the millennia. From this sediment they hope to find out whether changes in the climate in the Neolithic period sparked off rapid cultural change. They are drilling from a raft, which turns out to be a rather unsteady business, and it turns out that the passage of time didnt make it easy for them either. The deeper they drill, the harder it gets. Will the Wacker, a kind of pneumatic hammer, help?
