I hope you're referring to the language in the video, or is there something I missed (I'm not a native English speaker...)
B.T.W: And I'm not the guy in the video ....
EDIT: oops, I just googled Jettle, that was a term I could not know as non native speaker
Sorry if it was inappropriate, wouldn't have known... I just thought it was a contraption op Jet and Kettle, which seems pretty reasonable .
