One's tendency when one is young is to do experiments just to see what will happen, without really looking for specific things at all. I first set up a little laboratory in the attic at home just to grow crystals or try experiments described in books, such as adding a lot of concentrated sulfuric acid to the blood from a nosebleed which precipitates hemotin from the hemoglobin in the blood. That was quite a nice experiment. I still remember it.
