I have decided to go for my PhD.
After exhaustive search of the literature, I have noted there is not a single case of a shark of any species ever having attacked a compass binnacle.
I shall therefore base my thesis on on the proposal that sharks are repelled by magnets. I hypothesise that the field of a reasonably strong magnet will disrupt the sensitive navigational function of their lateral lines.
I shall test this hypothesis by putting a couple of fridge magnets in the pockets of my swim shorts, and going swimming in heavily shark infested waters, which is what Australians call the sea.
This is an exciting project with serious implications for bather safety worldwide. I am eager to get started.
I have “I crossed the Nullarbor” and “buzzy bee” fridge magnets in my pockets,. I’m off for my first field test. In the words of Captain Oates, “I may be some time”.
