Computer dunked in fish tank

You may be asking yourself: is this not completely pointless? On the contrary: if some of the more alarming Global Warming projections turn out to be correct, those of us who live near coastlines shall need to know how to keep computers working underwater. Not to mention fridges, cars, TVs etc.

Perhaps next these students can work on gill transplants.
