Design student Michal Shabtiali has developed the appropriately named Portable Fish Bowl. It's a fishbowl with a handle. Making it portable. See how that works? It's a concept piece at the moment, but after word gets out I imagine mass production will begin in no time. After all, if the batty ass lady next door can walk her damn cats (read: push them in a stroller), I don't see why you can't take your fish out for some fun. Just don't leave the poor bastard on the subway.
A few more after the dive.
