I have a lot of free time recently, but I don't want to spend money on equipment and materials to cultivate new hobbies. Most of the hobbies I see on the Internet require pigments, musical instruments, sports equipment or paid membership. I don't want to spend money on it for the time being.

I want to find something that I can do in a fragment time and completely without any expenses. It can be done indoors and outdoors. I can do it alone or with others.
