Warning: this link consists of graphic pictures depicting removal of a fingernail by gigantic freaking magnets. [Dirk] likes to gather strange things. A few of those strange things, just occur to be huge Neodymium magnets. even though he was truly really careful, somehow two of them ended up close sufficient to draw in each other. After a short flight, the two collided with his finger idea in between them. It is most likely still there now.
We understand these things can be quite hazardous as well as normally alert people when doing jobs that need them, like building a wind turbine.
