OK well gauze is something different. A screen is what is used to hold your marijuana while you light.

SCREEN=FOR ALL BONGS---A MUST for most new pipes

A waterfall is in fact something different my friend. A waterfall is more of a bong than the gravity bong you were talking about

there are different varieties of the gravity and the water-bong.

The "waterfall" he mentioned is the commonly known "Gravity Bong"
A nice variation of the gravity bong is the

bag bong:
Instructions to make:cut off the bottom of a 2 liter pop bottle and duck tape an airtight bag with no holes to the bottle. Make sure the bag surrounds it and makes it airtight
then push your hand inside of the bottle surrounded by the bag.

For the top of this you need a 5/8" socket and some filters out of your kitchen sink(they got hundreds) stick 1 filter inside of the socket and then cut a hole on the top of the bottles bottlecap that fits into the socket. Duck tape the socket to the cap making sure its airtight. Then you screw it on the bottle, Put your cannabis powder or small pieces into the top of the socket. You can see here that the screen makes sure your weed doesn't fall through the socket and into the bottle.

Now Just put a flame too it while u pull the bag back out of the bottle. (thats what creates the suction)

Now personally I much prefer the TRUE waterfall. A waterfall is a water-bong, however A water-bong is not necessarily a waterfall...

Now just take the cap/duck-taped socket off the bottle, Get a new bottle and cut a little hole at the bottom that you can cover with your thumb. Fill that up with water while keeping your thumb on the hole. Next screw the cap/socket(this is called a bowl)SO screw the bowl onto the bottle(bong) Put your weed in, and then take your thumb off the hole. Next before too much water escapes put the flame to the weed. The smoke will be sucked right into the bottle and will fill it up. When the last of the water leaves.(you can leave some water in if u want a bubbly noise when you toke) Then you put your thumb back over the hole,

Next You have to unscrew the bowl and before too much smoke escapes(it shouldn't if your thumb is on correctly) Take the biggest toke of your life, or choke and cough and want to die. :rastasmoke: Or if you're a wuss you can just take dainty tokes and cover the top of it with your hand in-between.

A good alternative to the 2 liter bottle is taking 2 or 3 watterbottles and cutting the bottoms/tops and duck-taping it into a big ass bottle that flows smoothly. If you do it right it actually looks pretty sick. Make sure to take labels off so you can see your smoke.
