I vaguely recall a few years ago seeing a picture of a rabbit in a box (walls were see-through like glass), which was underwater, and this was meant to be made of a material which would exchange the carbon dioxide breathed out by the rabbit for oxygen from the water. I have become increasingly dubious about this, and I reckon it was probably one of those things that newspapers produce on 1st April each year!
