Fish Tank Friday: Open Bottom Tank

By Evan Ackerman

This is another one of those awesome and weird fish tanks that manages to suspend a whole bunch (in this case, 220 liters) of water vertically without it all spilling out. Once a gate is opened, the fish in the tank have free passage between the top and the bottom parts, and making the transition doesn’t seem to bother them in the least. Not that I’m one to know what really bothers a fish.

As far as the physics goes, my guess is that even though there’s air circulating through the top of the tank, if it’s a closed system, the volume is still constant and the water can’t get out. That’s my guess, anyway. The guy who makes these tanks lives in Singapore, but there’s a lot more info (and more videos) on his YouTube channel.
