High Tech Engineering
So what is my goal? Push the envelope of bong design to new highs, those unseen by anyone else. This is what real engineering is about. Take your 2 liter and shove it up your ass. I am smarter than you are. Eat my nuts.
Physics and other mathematical bullshit
PV = nRT
If you don't know this you must be a complete moron. It's the Ideal Gas law. To simplify things, all calculations will be done considering we are working with pure air, since we don't care about molarity or anything like that because chemistry sucks. That means n (number of moles) and R (a constant that has to do with moles) drops out. And because the temperature changes really don't have that much a difference on pressure during operation, we can assume T is constant since we are calculating everything with air anyway - which means we are calculating this as an ADIABATIC SYSTEM. But that means jack shit to you so i'm not explaining it. This gives us.
PV = constant
THIS IS TK'S 1ST FUNDAMENTAL LAW OF BONGS! Rearranged, we see that (generally)
P = (1/V)*constant
Which since your an idiot have no idea what this means. To us smart people, this means PRESSURE IS INVERSELY PROPORTIONAL TO VOLUME! To you dumb people - the bigger you make your bong, the more pressure is needed to pull the same amount of air. Since you're only used to crappy inferior materials, consider a 20oz soda bottle and a 2 liter soda bottle with the same size hole cut at the bottom. Inhaling through the smaller bottle will result in more pressure available at the hole compared to the 2 liter's. WHY? Because the amount of pressure given is equally distributed over the inside surface of the bottle. Since the hole is the same size on each, the smaller bottle has less area, which is why there is more pressure available at the hole. Duh. This is why that stupid ass 2 liter bong takes a lung and a half to pull. Why else does it suck?
Flow Rate = P/A
Yes, the bong sucks because the chamber fills slowly. As you can obviously see, the bigger the area of the tube which it flows through, the slower the smoke. Why should you care about this?
SMOKE STALENESS INCREASES EXPONENTIALLY OVER TIME RESULTING IN NASTY, HARSH SMOKE!
why else?
THE LONGER SMOKE IS IN THE CHAMBER, THE LOWER ITS TEMPERATURE GOES, THE MORE OF IT ENDS UP IN RESIN FORM ON THE INSIDE OF YOUR BONG!
The faster the smoke makes it to your lungs and the less time it is in the bong, the smoother the hit! This is why that gigantic "KONG BONG" which is seen in every generic bong making faq sucks. It takes so long to clear, all the smoke will be stale. What moron designed that one anyway? They might as well call it the "Eat my Schlong Bong."
Guess what. There's another reason why your 2-liter bong sucks. Any moron can see that you need extra pressure to move the smoke through the water.
Pressure Needed to displace water = submerged tube depth*area of chamber
Where does the area matter? Water is a fluid. Duh. When water is displaced, all of it from the submerged tube up push back against the submerged tube, trying to displace the air. This means the more water you have, the more backpressure. Lets not forget that greater area means less pressure available to begin with.
So what have we learned so far?
Less volume = More pressure available
Less cross sectional area = lower rate of flow
Less volume of water (submerged tube depth*area of chamber) = less backpressure.
So what can you do with these 3 relationships? Meet Deuce, the exceptionally smooth, suprisingly easy to pull, double chamber hookah. I'll explain the details of it eventually.
More lessons when i feel like it.
