Wonders are everywhere

Happy Christmas hivers. I have been imagining what I saw that beats my imagination and it is till a wonder in my site. Below is picture of an abandoned water tank. Looking on top carefully, you will see at the top left hand side a tiny plant on top of this metal tank. What beats my imagination was that, how could a plant grow on top of metal where there is no soil for it to be rooted?
