Any good & simple way to use an ecig style cartridge vape with a bong?

I know the whole purpose behind these pen style vaporizers is for portability, but I often find myself using them at home wishing I had a way to run the vapor through a bong to make it smoother. Anyone know of a good way to do this?

I made this to use with my wife's Ego Ecig (it works with a bunch of different size mouthpieces)

(note, not all ecig style vapes can work upside down, you might need to get a PNWT style vape to keep your ecig upgright)
