When the Andernach geyser awoke
In the "borehole" you follow the geyser water to the eruption
After your stay in the Slate Cave you enter the next visually impressive area of the museum: the borehole. Watch out! A huge, two-metre drilling head seems to be breaking through the rock face right now. Fortunately, it is part of another breathtaking scenery. But why a borehole? And what does it have to do with the Andernach geyser?
In order to provide the carbon dioxide with a way out of the depths, a hole was drilled in the Namedyer Werth Peninsula. Normally, theCO2 would have slowly risen to the surface through small gaps and pores in the earth. But now there was a much faster way up. Now the highly pressurisedCO2 could escape all at once, and it did so with tremendous force - the Andernach geyser erupted for the first time. At that time, by the way, it was still called "Namedyer Sprudel".
But similar to the slate cave, here you will not only be amazed by the elaborate design. Various Exhibits are waiting to be tried out and examined by you. With hand drills, you find out for yourself how different types of rock behave, what density and degree of hardness they have. But your geyser expedition is not over yet, it continues!
