Makeshift Bong Slide

So You Want to Make a Makeshift Bong Slide

I've built more of these than I care to count, mostly out of necessity when you're somewhere without access to anything decent and you just want it over with. A makeshift bong slide is essentially a tube or pathway that connects a bowl area to a water chamber, letting smoke travel through water before hitting your lungs. It's not pretty, it's not efficient, but it works well enough if you don't overthink it. Grab two plastic bottles — a 2-liter soda bottle for the main chamber and a smaller water bottle for the mouthpiece section if you have one. Cut the bottom off the larger bottle. Cut the top third off the smaller bottle so you have a funnel-like piece. Poke a hole in the cap of the smaller bottle for your downstem, or just remove the cap entirely and place it upside down into the larger bottle so the funnel part sits inside the main chamber. Fill the main chamber about a third of the way with water. The water level needs to be high enough that the opening of the smaller bottle sits below the surface but not so high that it floods when you inhale. That last part is something I learned the hard way — filled mine to the brim once and sucked water straight up into my mouth. Took forever to clear that out. Now I fill to about the halfway mark of where the small bottle's opening will sit, and it stays reliable.

The downstem is usually the weakest point on a setup like this. A metal paperclip bent into a U-shape works if you're improvising on zero notice. Wrap some aluminum foil around the base to create a bowl attachment, or just use a small piece of foil as a screen and rest it over the downstem opening. Don't pack material directly onto the stem — it'll clog within seconds and you'll be picking debris out of a paperclip at 2 AM. I use a tiny ball of steel wool between the foil bowl and the stem as a permanent screen solution. Holds up through dozens of hits. When you're ready to use it, place the small bottle upside down into the large bottle so the funnel end is submerged. Light the material in the foil bowl while inhaling slowly through the smaller bottle's opening. The smoke travels through the downstem, bubbles through the water, and comes out the other side. Slow draws are critical here. Rush it and you'll pull water up into the chamber instead of pulling smoke through it. Takes practice, same as any bong, but this rig has less volume so it responds faster and punishes aggression more quickly. The biggest problem people run into with a Makeshift Bong Slide is condensation clogging. Water vapor condenses inside the narrow passages between the two bottles, especially if you're taking rapid successive hits. The passage narrows, airflow restricts, and you end up with wet ash instead of clean smoke. I solved this by tilting the whole thing slightly after each hit to let condensed moisture drain back into the main chamber, then keeping the upright position between hits. Not glamorous but it keeps the thing running without taking it apart mid-session.

Another thing worth noting — these rigs don't filter nearly as effectively as glass. The plastic bottles leach a slight taste into the smoke, especially when warm, and the water chamber is too small to do meaningful filtration. You're going to get a harsher draw than anything from a proper bong. If you're doing something resinous or damp, expect it to feel like sandpaper going down. Dry your material thoroughly before packing, and don't load it heavy. Half a gram at most keeps things manageable with this setup. The main bottleneck with this approach is durability. That foil bowl tears if you press too hard. The bottle connections loosen after a few uses and you start losing suction. And you can't really clean it properly — water gets trapped in the threads and the joints, which becomes a mold problem if you reuse the same rig more than once or twice. I tend to build one, use it for a single session, then dismantle and discard unless I'm in a situation where building a new one takes less time than cleaning the old one. If you have access to even a cheap glass bong from a head shop, spend the ten dollars. This rig is for emergencies and camping situations where you can't carry glass. It works, it just doesn't work well. Know the difference before you invest a lot of time trying to make it perform better than it actually will.
