Sense Sonnet - Pumper

 Mysterious Spring

Discovered, 1943,

When I was knocked off of a shelf.

"Walked" down a bunch of books, did me,

Discoverer wowed by myself.

There be no magic in my act.

Gravity and energy flows

Make me a scientific fact

Whenever "magic walking" goes.

I was meant for big time, I guess.

Sleek and sinuous means my name.

I became a commercial success,

For decades have had worldwide fame.

Who is this mysterious spring?

I am Slinky, a wondrous thing.
