"Necessity" is a fickle word and and even more elusive emotion, especially when discussing that quality in others. But there are some things that look, well, just completely unnecessary; so very unnecessary that they are just plain wrong. Hard to identify, difficult to codify--but everyone knows it when they see it.
Such is the case of this fish-throwing machine installed at the London Zoological Gardens. The wooden tower seems to be 12 feet high or so, with a fish launched from its uppermost window once a zoo patron deposited their sixpence, eager to mechanically feed a sea lion. Patrons to the zoo at Regents Park who were eager to see the sea lions fed had to arrive at slimly-appointed time; now, with the fish thrower, they could see the sea lions fed at any time, and do it themselves if they were so inclined. I don't know exactly what happened to these beats, but constant feeding would've have gone all that well.
And yes, you got three fish for sixpence.
