Gravity

Keeps everything exactly where I left it. Never had an item float away. Slightly clingy but I've made peace with it.

Went without it for six months on the ISS. Missed it more than I expected. Nice to have my coffee stay in the cup.

Works a little TOO well. Every time I drop something it goes straight down at maximum speed. No grace period.

Best part is it always gives you back down after up. Consistent.
