Hamsters liking water?

[PurpleKat]

So both me and my friend have hamsters and we talk about their weird habits.
Her's has started to wash with water from its water bottle.
From the video looks like just a quick one, but it does it periodically.
I always thought they didn't like to get wet.

She has a sand bath which it uses, and seems happy and healthy.
Should she be worried?
I'm worried about her hammy as that's very odd.
