We’ll show you just how low-tech a sploof can actually get in a section below. But first, it would behoove us to talk about the etymology of the word sploof (that’s where the word came from for those of you tripping balls right now). The omniscient internet is decidedly vague about where exactly the term sploof came from so maybe it’s not as omniscient as we all thought. Regardless, it’s not hard to conceive of the word sploof as a portmanteau (a blend) of the words “spliff” and “spoof”.
Spliff is a word—possibly a portmanteau itself—of Caribbean origin that refers to a combination of tobacco and marijuana rolled into the shape of a joint , cigarette, or blunt . Spoof is a more familiar term that refers to a trick or a hoax played on someone as a joke. It’s easy to imagine one industrious spliff smoker (the genius mentioned earlier?) coming up with a way to mask the fact he was smoking marijuana by blowing his ganja smoke through a filter. And in proper marijuana fashion, this intrepid inventor gave his creation a name that would confound people to this day. It can be built from things found around the home or require a trip to the hardware store. It all depends on your needs, how much you want to spend, and how long you want the sploof to last. All sploofs are built around the same basic principles: an enclosed tube with holes in both ends filled with some filtering agent. Before we talk about the tube and show you four different things you can use, let’s talk about the filtering agent. Dryer sheets are the cheapest and easiest-to-obtain filtering agent for your sploof.
Chances are you’ve already got some lying around the house somewhere . Dryer sheets work great because they’re often infused with their own odor which works to neutralize the smell of your weed smoke. As an added bonus, the thick weave of the dryer sheet material further traps the molecules that cause weed smoke to give off its tell-tale aroma. If you don’t have a box of dryer sheets lying around, $5 at your local market is enough to keep you in sploofs for a month (depending on how often you smoke). Activated charcoal—also known as active charcoal, activated carbon, or active carbon—is one of the best gas and odor filters available. It’s so good because each “piece” of the charcoal is extremely porous. In fact, because of its high degree of microporosity, just one gram of activated charcoal—which can fit in the palm of your hand, by the way—has an actual surface area of 32,000 square feet. That number might not mean anything to you, but in terms of adsorption (yes, that’s the correct word), it means that activated charcoal has plenty of room to trap and hold the marijuana molecules that make your smoke smell. Though it may sound difficult to obtain, it’s really not. You can find activated charcoal at most pet stores because it’s used in aquarium filters. It’s a bit more expensive than dryer sheets (about $12 for 22 fluid ounces), but is much more effective at getting rid of the ganja odor that will give you away. Dryer sheets will do a good enough job to keep your smoking undetected, but they won’t last as long as activated charcoal. The type of filtering agent you choose can also be dictated by the type of container you use. We suggest trying them both in various builds to see which one you like best. These DIY-projects aren’t expensive by any means so you can try different forms and combinations based on your own needs and designs. Now that we’ve discussed the filtering agent, let’s turn our attention to the container that will hold the “guts” of the operation and how to assemble the numerous variations. First, remove all the toilet paper from the cardboard tube. It’s best to wait until you actually finish the roll so you don’t have a pile of toilet paper lying around. That’s a sure sign that something untoward is going on. Be sure to remove all the little bits of toilet paper that are caught in the adhesive. Second, fill the tube with three or four dryer sheets. Just make sure they’re spread out so that they fill up the entire interior of the tube. Third, cover the end of the tube with another dryer sheet and fold it over so that it covers part of the length.
Secure this dryer sheet with any kind of tape, a rubber band, or even string. Just add fire (to your joint, of course) and blow the smoke from your tokes into the sploof to filter out the stinky marijuana smell. The toilet-paper-tube sploof will last for several smoke sessions but be sure to keep an eye on the dryer sheets. When they’re running out of filtering power, they’ll begin to turn dark. When that happens, just toss your sploof in the trash and start again.
The toilet paper tube may also wear out sooner than the dryer sheets because the cardboard is made to degrade in the presence of moisture (your breath). First, cut the plastic pop bottle in two about half-way down. Basically, you’re just cutting the bottom off, so feel free do that if it makes more sense to you.
