Chemistry class is way more interesting 

When we conduct labs. Look at the zinc 

wrapped up in the cold pristine copper, 

See how it begins to glow and shine above 

The flame. Look, it's oozing, plummeting 

Towards the heart of the bunsen burner.

There it goes! A shimmering melted mass

contained by the metal pipe bubbles, content

Until the fire flickers and goes out, 

Smothered. Quicker than a blink, the zinc welds

To the burner, refusing to lift away as the metal

Grows chilly. After class our teacher must 

Get rid of it so that the burner will work.

He'll use a chisel to pry the hardened mass 

Away from its unwilling, crippled host. 

Every shard breaks into a million fragments

As he chips away, piece by painful piece.
