Body Chemistry 

Our bodies perform 

lots of chemistry tricks

to break down our food 

into useable bits.

 

We also have microbes 

inside us to aid

with eating the chemistry 

soups we have made.

 

These frothy reactions 

will bubble and pass

some carbon dioxide 

and nitrogen gas

 

which tries to get out 

of our digestive parts

by causing our bodies 

to make lots of farts.

 

Those microbes make 

hydrogen sulphide as well.

A gas we all know 

by its terrible smell.

 

It’s not what we’ve eaten

or what we might drink

but mostly those microbes

that make our farts stink!
