Hey guys, I need your help. I just ran over to the local headshop to get a bowl and a downstem to make a bong. They gave me the 4 pieces shown in the picture. Downstem, Bowl, and 2 rubber thingies. My question is, what do I use the pieces of rubber for? My friend has a glass drill bit, so I'm probably gonna make it out of an old alcohol bottle. If I cant get the drill bit, I'm just gonna make one out of a water bottle. Any help would be much appreciated! Thanks!
The rubber is to make the Ceil tighter. So that it's air tight. make the hole with the female piece and then put the rubber on the female piece and slide it into place, put the other rubber on the slider.
