I found this rock in my back yard. I suppose it has been there for ages. It weighs about 10 kg and when I tried to cut it with machinery, I couldn't.
Some facts about the rock:
- I live in Cyprus.
- It has the size of a head of a 7-year-old kid.
- It weighs around 10 kg.
- I used a hand cutting machine like the one in this photo.
