Mr Archimedes' Bath (written by Pamela Allen)

A story about a man named Mr Archimedes who takes baths with his animal friends, Kangaroo, Wombat, and Goat. Every time they bathe together, the water overflows, leading Mr Archimedes to investigate who is causing the extra water. Through a series of experiments, they discover that the overflow is due to the combined volume of all the animals in the bath, not any one individual.

Written and illustrated by Pamela Allen.
