Is this a bong?

I found this in my draw i cant remember buying it but is it a bong?
if so how does it work because there no were for the herb...
advice pleaseee

it looks to be a part off a hooka or sumthing anyway cause u can see the down pipe and all.. i think your missin a few vital parts amigo

its a old type of optic, ie you fit a cork over the big tube and it fits in a bottle, then u can pour liquids without spilling my mum run a pub in the 70s and they used them for diluting drinks so they could just give it a dash of blackcurrant or whatever, but am sure with enough thought you could use it to smoke somehow

Yeah it looks like something that goes on top of a bottle to dispense perfect shots.

disregard that..
i recon its a drinks despenser also
