 Serendipity

Alexander Fleming one day

In 1928 did set

Bacteria samples to stay,

That he needed to study yet,

In his lab in a corner dark.

Fleming then left for quite a while

On a vacation to embark.

When he got back, he found the pile

Of bacteria, now all dead,

Due to being covered in mold.

His further study of this led

To a great finding to unfold.

Penicillin, miracle drug be

Discovered by serendipity.
