Row, Row, Row your boat
Over at Swans on Tea there was this gem today
The comments on the YouTube video got me thinking:
So if the density of Mercury is 13.5 g/cm3 and we assume Jesus weighed something around 80 kg, then he would be able to walk across a pool of Mercury with less than 6000 cm3 displacement. If his shoes are about the size of the ones I have on, he would sink up to his ankle.
