Can you guess what is my hobby? If you said doing experiments and calculating you are right. That is not only my hobby, it is my passion.

One time I grew tiny crystals under a microscope. They formed a regular network of bars that look like a maze. After 2 weeks I looked at it and found there where explosions in the intersections. I decided to investigate. Every half-hour I recorded my observations. There where more and more explosions only in the intersections. Why, I don’t know, but I have a suggestion. Maybe there was a little bit of liquid left inside the bar, which evaporated and made it explode
