One Cube or Two?
One Cube or Two?
When
we were at school as children we were made to wear indoor shoes inside the school
building. The teachers would never let us wear our outdoor shoes at all and
they made us change in the changing rooms from the moment we entered the
building. I'd never known teachers be more strict about any other school rule.
The trouble was that my indoor shoes really made me suffer because they were so
tight. “Let’s expand our shoes!” a fellow sufferer suggested. He had had a
brilliant idea. We put plastic bags inside our shoes and poured water into the
bags. We sealed the bags carefully and put our shoes into the freezer. Of
course the ice made the shoes expand and they were a pleasure to wear. This
clever idea help me to get through my schooldays with less discomfort and I
have never forgotten it!
