When you’re in space and you want to set something down, like a spoon or a Sharpie, you don’t actually put it down. There is no down. You set it out at arm’s length and let go and float it there where it’ll be handy if you need it again. On my second day home I was unloading the groceries from the store. I grabbed a bag from the back of the car, took it out, stood up, set it out about shoulder high, and let go. It didn’t float.
