What is the science behind it?

Colored oil over colored water or something like that. Looks nice, but it's kind of annoyingly noisy.

Can I refill with different water?

Hi I looked for it I couldn’t find anything about it I think it may not be changed Thank you Sincerely Gourmet depot USA

How long does the battery last?

Hi, there! I am still on my first battery (size C). I've been running my machine at least 8 hours a day for over a week now and haven't seen any signs of my machine slowing down. It's a simple rocking motion and I doubt it uses very much power.
