you will probably want to get somthing very very sharp to be able to cut into the glass without breaking it...a drill will work really well.
then you need to make a slide...you can make a desent one with a pen, small funnel or tinfoil, and a small rubberband. But since you have such a nice glassbong piece you might want to invest on buying one or you could make a carb hole on the side of the bong that you just cover with your finger...
and make sure you make the slide go in at an angle, so its beneath the water....
