Heat up your flask until it's hot
It's either ether, or it's not
And if it boils when slightly warm
It might be meths or chloroform

Don't know, don't know, don't know, I know x3
Don't know, don't know, don't know

(chorus)

With a fume hood, it's less dangerous
Here's a sample, in containers
I smell solvents and reagents
Here's a sample, it'll stain us
Ethanoic
Means acetic
Aromatic
Make me feel sick
Yeugh!

I thought that what I had was meths
I got it wrong, but then I guessed
Does this stuff smell like pears to you?
Amyl acetate does too

Don't know, don't know, don't know, I know x3
Don't know, don't know, don't know

(chorus)

(Solo)

And I forget I should not taste
And now I guess I don't feel well
It smells so bad, it's bad to smell
This stuff, mercaptoethanol

Don't know, don't know, don't know, I know x3
Don't know, don't know, don't know

(chorus)
With a fume hood, it's less dangerous
Here's a sample, in containers
I smell solvents and reagents
Here's a sample, it'll stain us
Ethanoic
Means acetic
Aromatic
Make me feel sick
A mercaptan
A mercaptan
A mercaptan
