    I once dragged one of those ceramic powerline insulators across two international borders because I found it lying around and liked how it looked. It took up the majority of the space in my backpack, so I had to buy a second backpack and carry it on the front of my chest lol. Apparently the reason they have that odd shape is so that when it’s raining, water can’t make a continuous trickle between the wire and the pylon

      That and also to increase the distance any charge has to travel across the surface of the insulator.
