[@mandi8345]

On the fancy one I was like "....wheres the siphon? isnt it just flowing back down through gravity?" But the handmade one is much cooler! Reminds me of a rig I through together to make HCl, had to make an elongated U bend tube to make a dual flask catch system so when the final suck happened at the end of the reaction the cold water bath used to capture the chlorine didnt end up in the hot reaction vessel. The awesome part is because it was a double flask setup the suction transferred the final acidified liquid out of the bubbler rig and into a conical flask for me! No need to carefully take apart the bubbler rig while juggling a wet jar of unknown concentration acid, or risk spills transferring to a flask, its already contained and ready for titration! Very efficient! 🤣 About 56% concentration (IIRC) for anyone interested. Not bad for my first go, IMHO. DISCLAIMER: I am not a chemist, doctor, or lawyer. I am not your chemist, doctor, nor lawyer. This does not constitute chemical, medical, or legal advice. Under no circumstances should untrained individuals attempt production of HCl by mixing table salt and sodium bisulfate (Ph down pool chemical) in a roughly 7:3 ratio, and pass the resultant gas of "!!!DEFINITELY DO NOT BREATH THIS!!!" slow-and-painful-death yellow-green through a chilled column of water in your own home.......Use a friends home, in case anything goes wrong. 😉 But seriously, the only person on this planet who is obligated to act in your best interest is yourself. Period. Will that ratio emit chlorine gas? Or will it blow the roof off the house? If you dont know, dont try it. I am not your friend, the internet is not an inherently safe space regardless of what the ToS says, the ToS is only words in a text document not laws of the universe enacted by god themselves, I am ultimately just some anonymous asshole leaving a comment. For all you know I could be a duck typing this on a stolen laptop in the French Rivera. You have no reason to trust me, I have no obligation to tell you the truth. This is how the internet has, does, and will always work. Those who try to hide that from you are ultimately doing you a disservice when it comes using your mind and accumulated knowledge to protect yourself from the very real horrors that exist in the real world. Only you can prevent stupidity, scars, broken bones, and death. Dont be a dumbass. The world is at a surplus right now, and it doesnt need your help.......

[@Ender.wigginn]

I love this video Mr. Beals; I'd like to think this would be an awesome demonstration for a high school chemistry class, but I'm not sure how attitudes towards students and caffeine have changed since I graduated; I remember energy drinks were a huge controversy back in '07-'11. In any case, I did want to note that the vacuum explaination was a wee bit off. This is a bit of knit pick, I know it is conventional, even in science classes, to describe a vacuum as sucking or pulling a liquid or gas. However, it isn't the low pressure in the flask that does the syphoning work, the syphoning work is done by the mass of the whole atmosphere above the brewing beaker. I mean technically speaking, the pressure in the flask does initially do work on the water in the flask, pushing against gravity and the rest of the atmosphere, to move the liquid water though the glass tube and into the brewing beaker, then the atmosphere pushes it back as the pressure falls to restore equilibrium. My point is vacuums don't actually suck, the higher pressure side of the pressure differential pushes. Again, this is more of a knit pick, I didn't learn the correct way to think about pressure differential and vacuum until uni, but it may be a cool way to challenge student's perspectives and preconceptions in the lab. Milk shakes are hard to drink because the atmosphere simply doesn't exert enough force on the surface of shake in the cup to allow the induced vacuum in the straw to overcome the intermolecular forces between the emulsified cream, milk, flavor, and ice crystals and produce speedy movement through the narrow straw. I did an experiment my freshman year of college using a bicycle pump with gauge, a metal water bottle, an o-ring, one one-way air pump valve, two silicon seals, one one way pump valve from a bicycle inner tube, metal straw, a small bit of clear plastic tube, and an alligator paper clip. I put a thick milkshake in the bottle, sealed the lid and straw, and pumped ~1.2 atm of pressure into the container. It was much easier to drink, not because I was providing more suction but because the pushing pressure of the extra gas confined in the container allowed for a higher pressure differential. Though, if you did something like this in class, I'd suggest scrapping the pump (which contains machining oils), and using some rubber tubing, a 2 mouth round bottom flask, an addition funnel, and use a sodium bicarbonate/acetic acid reaction to produce co2 for the pressurization. You don't want a lot of pressure here, the goal isn't to fountain milk shake out of the straw, but rather make it easier to drink so students can get a better intuition for how vacuum and pressure differentials work. You could substitute smoothie instead of milk shake if allergies or sugary treats pose an issue with admin, though you may need to adjust pressure and your smoothie thickness accordingly. Having students calculate how much acetic acid to add to produce the desired volume of gas and thereby the desired pressure might make it a bit more on topic for a chemistry lab, rather than a physics lab 😁

Nice job. Personally I would be interested in building some type of apparatus that actually brewed the coffee in a partial vacuum. I think it would be possible to brew at a much lower temperature and get a smoother cup if the vessel that the slurry was heated in was under vacuum. It would have to be hermetically sealed with some kind of a valve to allow it to flow back once brewed. Perhaps it could be done with steam. Maybe having a vacuum suck heated water vapor through a filter packet of some kind and deposit it in a trap. Any ideas on how this could be done?

I used paper filters (actually two filters because one tended to rip during the vacuum phase) but I would like to try cloth! That would probably be a better choice!

[@user-zh4vo1kw1z]

This has made me want to make a small serving version of this. Perhaps even expand to the Belgian Balance Siphon if that works. For the "normal" one though, i was wondering...: I'm thinking you could probably do without the tubing with a fritted glass or Buchner filter. that way it would still be a single column and thus a lot more managable.... But I don't have a background in chemistry, so am I missing something?

[@BealsScience]

Your thoughts are correct. You can make something like this in a single column. I added the glass tubing because I thought it would be interesting to see the coffee moving between the containers.

@@BealsScience Well, I think you'd need to set up a thermometer because for white / green teas the temperature for brewing needs to be 80C, black / pu'erh teas 100C. If you have water that is too hot for white / green you run the risk of burning the leaves and the flavour turns. I've watched your videos a few times as I always keep coming back to this idea so I don't think the process would be much different from coffee, just need better temperature regulation of the water, and a way to easily time and siphon off the tea. I would suggest collecting into a boiling flask that perhaps is on a pivot point that you can pour into a mug.

Would the coffee brewed in the store bought siphon brewer be brewed too hot? It seems that the brewing coffee in the store bought one is boiling as well, the homemade one doesn't seem to have the same issue of the coffee being as hot though. Also, this is definitely a much better quality video than the coffee chemistry video I made a few years ago for class.

[@BealsScience]

@@BealsScience I have never had any kind of siphon brewed coffee, but in my personal coffee making/coffee drinking(i.e. going to coffee shops) I prefer french press coffee, although pour over is okay too.

[@ROBERT_L.]

I own a store-bought siphon brewer. After several brew experiments, the top chamber never reached the boiling point. A handy digital thermometer stuck in the water on top, did not exceed 190°. It initially pushes to the top at ~165°. The bubbling in the top chamber must be a result of gasses pushed from the bottom and not from a boiling effect in the top container.

What a beautiful video that introduces the viewer to some of the wonders of siphon brewers, all of which come from a 1910 patent from our CONA brand. We are the 'Origin of the Species' worldwide, and the asian specimen Craig uses at the beginning of the video is yet another clone of the pre-WW2 model Cona 'De Luxe'. Since then our 'Quality-made-in-Europe' has evolved forward into the contemporary table model 'D-Genius All-Glass'. At our Cona factory, we make a "Marvel of Engineered Inventions". One of the most surprising of these, is our filter rod made of solid glass. It looks like a fishing bob with at some two-thirds of the stem a cone. This has a rough (sandpaper-like) surface that beautifully solves Craig's remark halfway the video about trial-and-error tweaking (of finding a suitable filter paper among your chemistry lab props). Scientists call this field of knowledge 'hydrodynamics'. How a liquid-solid mixture flows is science you can really wreck your brain on. If you give the liquid in the upper reservoir a twist at the moment you snuff the flame the brew returns to the lower bowl creating sedimentation of the spent coffee grounds in the funnel in the form of a perfect bell-shape. Beyond this the word 'Genius' also relates to the pyrodynamics of the new 2017 wick assemby. It is a sandwich construction of one inch of rope soaking up the alcohol fuel with essentially a cotton de-make-up-pad on top under a stainless steel mesh. For some reason the cotton does not scorch. Zero sutt means a perfect hot blue flame forms, zero wear means it lasts forever. This serves one of the goals of industrial design: durability. We cordially invite everyone to be mesmerized by seeing our coffee maker in action and reading the story on our website www.cona.be: Once you are there just click on "How Abram Games created the CONA design classic and shaped it to perfection using the scrapped plating of Spitfires ". Did we mention about how Cona coffee tastes? Well ... its on the menu of some Michelin-star restaurants in Europe.

Hi! How much time do you spend heating the water approximately?

If I have something available to boil the water before putting it in the brewer I will preboil it. Then it only takes a moment to get it back to a boil in the brewer. Once it is barely boiling in the brewer, I seal the stopper and let it go to work. Does that answer your question?
