Ok, This works too. Get a 2 liter bottle, about a quarter - 2/3 of the way up the bottle make a hole and put a hollow pen/tube down there [make it permanent if you want] unscrew cap, fill with soem water, put mouthpiece of pipe to the tube and suck through top. I've often broke bong slides and supstituted my pipe as a slide like this [great last minute fix] and it hits damn fine [unless your piece sucks]. But I suggest something more sturdy than a 2 liter, as to they crunch inwards, if you take a lighter to the outside walls and heat them up, they constrict and toughen, thus preventing it from crushing in as much, just dont melt the bottle.
