"Inverted aquarium"

This is a recent video, but the concept of a "fish tower" is not new.  I first bookmarked a German link for a "Fish Loft" many years ago, thinking it would be a nice thing to put in the pond if I ever have a shack in the north woods.

Most of the images and videos of similar devices suggest using a wet vacuum to exhaust the air from the tower, but all that would need to be done would be to hold the tower underwater until it is full, then invert it on a stand (it would need to be secured because it would be very tippy, especially after the local raccoons find it).
