I've always wondered how water would behave in 1/6th G.
Imagine an Olympic sized swimming pool:

Would the reduced gravitational pull, make a person "super buoyant", and unable to swim underwater, sort of bobbing on the surface, like a Styrofoam ice chest?

If you did a "cannonball" off the diving board, (Hmm, guess you wouldn't need a diving board) would the waves from the splash propagate more slowly, or at the same speed as with 1 G?

The architecture of living spaces would be interesting:

A "Fireman's Pole" might replace stairs. I'll bet you could climb 3 floors, one handed without breaking a sweat.

The "Great room" concept, popular in today's homes, might work well for 1/6th G, but with the outlying rooms distributed more in the vertical than the horizontal, and without hallways.

Beds and mattresses should be fairly simple, maybe just a thin pad of foam. Sleeping might be pretty nice in 1/6 G, due to the reduction of stress on pressure points.

Preparing and eating food, should be a little easier than in zero G.
I wonder if you could use open cooking utensils, like a wok? I'm sure there would be a learning curve, but something tells me people would adapt.
