is Dutch for Chemistry, and literally means "Separation Science". Now, if one has a carpet made of 85% polypropylene and 15% wool, how does one go about separating them?
Have no fear! Nature already has a solution. I found these cocoons (about half a centimetre long) on the surface of said carpet, and decided to look at them under a video microscope. This is what we saw:
As you can see, these caterpillars emerged from the cocoons and resumed their analysis, selectively removing the wool fibres from the polypropylene matrix.
