P4_2 Earth’s Toilet Trouble

Owen William Morris, Lewis Jefferey Banks, Aaron James Laird, Liam Stuart Morris


How large a radius would a toilet bowl need to have in order to cause the Earth to stop rotating? In this paper, a circular motion model of the common flush toilet is explored. By keeping the height of the flush constant and calculating the mass of the water for every possible radius; we have calculated that the toilet bowl would need to have a radius of 4.65 × 10^8 m. For this scenario to occur, the motion of the flush would need to be in a clockwise direction when located on the North Pole to cause the Earth to cease rotating on its axis.
