Chemistry 101

"Mix them very carefully"
Tells a lone professor
"You don't want to add too much,
As you see, I'm no hairdresser"

Foreign names of chemicals
All go in and out of my head
Hydrocloric acid,
Mercury and lead

Pouring them into a glass
I guess it's called a beaker
The concoction turns bright green
My attention turns to the speaker

"Don't do that!" the teacher calls,
"You've made such a mess!"
The classmates scuttle to my table
I've caused such distress

My mixture explodes with fierceness
Burning off someone's hair
"Hey, why does her's explode?"
"It just isn't fair!"

The last bell rings
So much for my fun!
I guess it's best to pay attention
