Do the twist! (Not related to Chuck Berry)

I have a twist in my bong on the shaft and I heard somewhere it's for ice. I really have no idea what for, or whatever. Can someone tell me what it's really for (if anything)?

 

show a pic?

 

it could be for ice, you just drop ice cubes down the shaft and they cool the smoke and makes it less harsh

 

I guess I'd have to slide it down when the bong is sideways, because the twist is pretty close to the water and it's a 2 footer.

 

i have a friend who has a zong. its pretty cool man.

 

fuck yeah its an ice chamber. it makes the smoke cold. i've only seen them on roor's, but it makes smoking so awesome. make use of it.

 

All sorts of bongs have all sorts of ice catchers. Roor uses three prongs, bongs like Hvy use a large indent, zongs use a crazy ben to keep the ice in place, sounds like yours is just a different style.

Stick some ice in there NOW!

 

Yeah mine is like a twist. I guess it's a pretty decent bong.
Here's what it has :

Ice catcher (twist)
Clear chamber
reverse spirals around the mouthpiece
nothing special about the rest of the glass
2 feet tall
free glass bowl and slider
20 free steel screens (used em or lost em)
$5 off a $25 salvia purchase (used it)

The whole bong package cost me like $69.99CDN which would be about $52 american.
