Gas came from nowhere ( Senryu Form)

I know that for future reference then Ben, I didn't know.

Hello Gel

Well done on this and - although Em is correct, generally speaking - modern senryu/haiku can be 17 syllables or less. She's written some good suggestions there, though.

Great stuff.

Haha Gel how funny, a great senryu though usually the syllabus are 5,7,5.

Here is my suggestion:
A gas emission
slowly released from nowhere
made thin air stinky.

All the best, Em
