Sense Sonnet - Pumper

Bar of Ivory Soap

More than a hundred years ago
"It floats" became the slogan for
A bar of ivory soap, so
Becoming part of ad game lore.
So why does the bar of soap float?
Proctor and Gamble did come clean,
The soap is pumped with air, but note
There still is almost pure hygiene,
Over 99% pure,
Plus 44/100ths exact,
All verified for sure, for sure,
To be advertised as pure fact.

A bar of soap that floats can be
Good for bathing in lake or sea.
