Another arc of energy that is about to collapse while another one is building right below. It's fascinating to see what wonderful magic nature can perform. If you keep in mind, that these are just electrons that race to the grounding wires with an extreme high speed and so heat the air and create light and sound that way, it is even more impressive. Especially cause these forms are so interesting and beautiful that. Oh I just love science and nature for that. Sometimes, you will just need to remember what the world around you does and what hidden, treasured beauties you can find almost everywhere ^^
