A5 7 Life Under Plastic, is it Fantastic?

Abstract

This paper calculates the minimum thickness of the polyurethane dome that the character Sandy Cheeks from SpongeBob SquarePants lives in to withstand the pressure on the seafloor of Bikini Bottom, and the minimum thickness of the dome to withstand the pressure at the deepest point in the ocean, Challenger Deep. We find Sandy’s dome would need to be at least 0.031 m thick to withstand the pressure at Bikini Bottom, and at least 5.6 m thick to withstand the pressure at Challenger Deep.
