When smoke cools, it becomes denser, so when it exits the incense at the bottom, it flows gently downwards.īelow you’ll see a video of the backflow incense cone in action:Īn overview of backflow incense burners ( aka backflow fountains, backflow waterfalls. However, in the case of a backflow incense, as it burns, smoke enters the hollow center tunnel, where it cools as it follows the along the path. But when a normal incense is lit, smoke flows upwards because the effect of the heat offsets the weight of the tiny particles, as hot air is lighter than room-temperature air. This is how we think backflow incense works: incense smoke is actually more dense than normal air at room temperature because it contains tiny particles. Backflow incense can also be made in the shape of a stick which is completely hollow in the center, ie, a long, thin tube. Most of the time backflow incense is made in the shape of a cone, with a small, hollow tunnel through the center, ending in a hole at the bottom center. What are backflow or waterfall incense, and how do they work?īackflow incense are exactly as the name suggests – incense where the incense smoke (or plume) flows in the opposite direction as “normal” incense, that is, downwards instead of upwards. So we hope that we can share some of this knowledge with you, and that it will be helpful in your incense journey. However, it is an incense form that we know a lot about, as we not only hand make our own backflow incense cones, but also design our own backflow incense burners from scratch (aka waterfall incense burners or holders). Over time, the form of incense we use has evolved from leaves, flowers,dried wood and resin pieces, to ground powder that is mixed and dried into different shapes.īackflow incense, otherwise commonly referred to as waterfall incense or an incense fountain, is a relatively new type of incense. Not only is the smoke cleaner but it is also much cooler so the user is less likley to have a coughing fit when trying to inhale the THC vapour.With a lot of the impurities removed the user recieves a much higher absorbtion of THC into their bloodstream than if they were to use the same amount in a normal pipe.Incense has a long history in almost all regions of the world.
Because THC is not soluable in water only the impurities in the smoke will get absorbed into the water ( nicoteen etc). Then violently shake the bottle for a second or two. The idea is then to remove the head then place a finger over the hole in the side of the bottle and a thumb of the other hand over the top of the bottle. Because the hole is made in the side of the bottle not the bottom there is a certain amount of water that remains in the bottle this is not a design flaw.
Most smoking noobs fail to grasp how a waterfall should be used correctly so their knowledge on the subject ends here. The drop in air pressure inside the bottle caused by the water draining out pulls the flame into the head which in turn ignites the smoking material filling the inside of the bottle with thick 'cream cheese' type smoke which (after removing the head from the neck of the bottle) the user then sucks/inhales the smoke in one deep breath (unless they are a lightweight) XD. Then the user removed their finger from the hole letting the water flow out from the side of the bottle while holding a naked flame (lighter/match) above the head. A head (13mm socket set + gause with a thin band of " Sticky Tack" wrapped around the outside to produce an airtight fit) is then filled with smoking material and placed into the top of the bottle. With one finger covering the hole the bottle is filled with water. This is traditionaly made from a 2-5tr plastic bottle with a 5mm hole melted into the side about 10cm from the base. An improvised smoking device mainly used for smoking hash resin through.
