How good do "lungs" work?

It'll only clear itself if the bag is able to completely contour to the bottle's shape. The way he has it now, it looks like the bag won't be completely sucked in when he inhales, and so it's possible that smoke would be left over.

Waiting for the smoke to slowly make its way out the top would be a pain in the ass, and while waiting for it a lot of the smoke could condense and coat the bottle.

If the bag is big enough, yes, he won't have any trouble at all as is. Otherwise, he'll either need a bigger bag or a carb.

I agree with stick, just make a sobefall...

yeah, you're right...fuck lol :stoned:

how do u make a gravity bong?

That lung is much too small.

We used to use 3/4 of the top half of a 2L pepsi bottle. Same idea, but we used a grocery bag instead.

It simple how they work. When you pull the bag down, the gravitational pull sucks the smoke from the bowl, filling up the upper half of the bottle.

I prefer the G-bong though as it's water cooled. A lung hits pretty hard.

All you need is a nut and a bottle. I have a 3 hitter gravity bong made from a one liter Gatorade bottle. I like lungs though, nice and compact .

I-beg-to-differ

lungs-will-fuck-u-up....trust-me

Yeah Lungs can get you pretty stoned if you make them right. But same with a gravity bong. If you want a good Lung then get.. a 2 Liter bottle and cut the end off, and grab a bread bag, Nice n big to give you a fat rip and it will help clear it out since the bags big. Then just add your piece where the cap would normally be and your set with a kick ass Lung.

When I used "The Lung" it was one of the biggest hits I have ever taken.

This is how my friend made it. He took a 2 leter bottle of soda and cut off the last 1/3 from the bottom. Then taped a plastic grocery bad to the end of the cut off bottom. And he made a bowl on the top with the cap and tinfoil. You stuff the plastic bag inside the bottle. Then you lite the weed and slowly pull down on the plastic bag from inside the bottle. By the time u can't pull anymore, the whole bottle is full of smoke. Unscrew the cap, and take that hit. Its pretty nice.

gravity bongs and lungs do basically the same thing but i think gravity bongs do the job better
