Wow this one just seems so wrong to me. The video shows a man who invented a deep fryer that is cleaned by way of a fish tank underneath. The fryer gunk drains into the tank and the fishies eat it.
It prevents people from having to clean the fryer frequently and from having to feed the fish. It also turns the fish into cannibals which is pretty effed up. I guess though that it’s as ingenuous as it is twisted.
