I got this bong for my B-day and me and a buddy were debating whether you need to put water in it or not?

I drew up a crude drawing of what i kind of looks like. There isnt really any big hole for water to enter. I took some pics of it but i need to develop them first before i put them up here if anybody would like to see.

blue line = smoke flow.
