Avatar Aquarium
It was created by a DIYer in China, and it replicates the lush green feel of the planet, albeit underwater.
the plants look a little like floating broccoli, but the most impressive part of the tiny world is the waterfall effect – which I had no idea you could do underwater. Basically, it’s done with very fine sand being pumped into a trough and recirculated back to the top after it falls.
