When I was much younger, I would hold my hand out like ๐ but with my thumb in the opening between my middle and ring fingers. Thumb-down, I would "fly" my hand through the hallways of my school as I walked behind my classmates. It was the easiest way for me to make a spaceship shape with whatever I had on me. I imagined the pilot sat in the thumb cockpit, despite the fact that it would obviously cause blind spots.
