Hi, Mr. Beals! I was looking up coffee filters used in chemistry experiments for an organic chemistry lab, and your video popped up. It was a very nice surprise! I look back fondly on all the time I spent in that classroom!
Hey Sophia!! Thank you for the kind words! You will always be one of my favorite students (don’t tell Madi...or Sam...;) I hope all is well at MSU! Good luck with OChem! That was my favorite chem class, but it can be a beast sometimes!!
I loved my science teacher in high school. He loved any experiment that had water involved! He was so funny and we learned without even trying or knowing it. Everybody loved Mr Livengood. You remind me of him. I bet your kids love you and your class! You rock!

Great video. And that reaction after it worked was really priceless. Your students should be so glad to have such a fun and motivated teacher. Keep up the great work.
This is exactly what i was looking for after that expensive price tag surprised that I actually find it. My inspiration was seeing its only a basic syphon I figured I can create it myself
I am crazy about coffee! My fellow Chemistry teachers at my school and I have developed an entire unit called the "Chemistry of Coffee" where students roast raw, green beans into amazing brews of coffee - and SO MUCH MORE! I will be sharing all of my videos, lesson plans, and information over the next few weeks. So, if you love coffee as much as I do, go over to BealsScience.com/coffee-science or watch the videos as they premier. And, if you have ANY suggestions or comments, I'd love to hear them! Thanks for watching ~ Craig
There is a filtration device 2l or something like that jar and a top with a funnel and mesh and an exit so you can use water stream to generate a vacuum
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?
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?
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.
Very cool, I'm wondering if I can incorporate this into a wood working type project. Being an engineer I really like the teaching aspect of things like this. Great job explaining it, and thank you :).
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.......
It is funny that you would mention a Büchner funnel! I’ve been working on two Cold Brew brewers made from chemistry equipment and both involve Buchner Funnels! If all goes well I should have a video for those in the coming months.
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?
I’m trying to make my own, would that clear plastic/rubber tubing he used as a connector work as a replacement for the glass tubing he used to syphon the coffee from flask to beaker or breaker to flask? I can’t find glass tubing like he had that bent so easily also don’t have a glass cutter
@@BealsScience You should taste the coffee after adding a pinch of baking soda. It's a great example of how baking soda neutralizes acids. An experiment you can taste.
Honestly i didn't expect it'll worked. Really cool style of siphon brewer, but still expensive if you don't have easy contact to this equipment. But still cool.
@@BealsScience You might want to stick a thermometer in the flask to see that the water coming in is 200*F, if it's higher add tubing and if it's lower, shorten the tubing. This is chemistry, let's optimize! :-)
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.
Your coffee video is great!!! My students preferred the coffee in the homemade siphon to every other brewing method...and so do I! It probably has a lot to do with temperature and timing. More research and coffee drinking needed to confirm...
@@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. The National Coffee Association USA has some guidelines on coffee brewing stating optimal coffee extraction is between 195-205F, and I'm sure there is some pretty in depth things people have done in their own time with regards to timing and temperature of coffee.
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.
I am not sure how well it would work. It probably depends on the filter. A fine filter may get plugged with the chocolate. But, you could skip the filter and put the cocoa in the beaker, let the water travel over to the beaker and once all of the chocolate has dissolved in the water you could remove the heat and let it travel back.
I don’t have exact temperatures for the water (I will work on building something to monitor it though - a lot of people have asked). I had never seen the breaking bad coffee maker until my video came out and people said it was kind of like the one in the show!
I was on American Science & Surplus’s (sciplus.com) website last evening looking at lab-ware for a similar. Love the funnel. Is it a paper or cloth filter?
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!
I came here because a chemistry professor used to make his own coffee every morning. Since I have not been in college for many years I wanted to see how it was done. I wanted to see if I can do it myself.
I know I came in late, but I do have a question. In the series it was mentioned that a consistent temperature was the key to a perfect coffee, in efforts not to get bitterness produced by high amounts of quinic acid levels. Is this something real? The setup looks good but I do not see any thermometers throughout the process.
Awesome a scientist performing this. I've always used boiling chips to distill or reflux. Q : Do you think boiling chips will enhance the flavor? Maybe a bit safer.
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 😁
That is an interesting idea! The flavor of the coffee definitely depends on the brewing temperature so it could have an interesting effect, potentially beneficial, effect on the flavor!
I have a strange question, since coffee works, would loose tea work as well; was just curious because I've always wanted to make something like this in my kitchen for tea.
You can definitely use it for tea. You might just have to work with the timing for how long you leave the water in the leaves to brew. Let me know how it works for you if you build one!
When I was experimenting I was using cheap grocery store medium roast because all my prototypes kept failing. Now I use coffee that we roast on our own! I’ve got a video coming soon that shows how to roast great coffee on your stovetop! And, it is legit good! Thanks for watching!
Is the boiling point of water the ideal water temperature to extract all the flavors present in the coffee grounds? Ive heard that slightly below 100C is preferable? Great video!
I'm curious how much oil content was lost through the steam. I might have to try out a steam distillation under vacuum once I can afford some brand new glassware.
But how does brewing it this way affect the taste of the coffee? Also you should always use whole bean and only blend it right before you brew it because a lot of the flavor comes from the beans releasing a gas after being blended and boiled
It's not gonna taste that radically different from a french press. It's still just coffee sitting in hot water for a while that is doing the actual brewing. The vacuum is just moving the water around and the simple paper filter he rigged to the end of the tube is doing all the filtering. The only benefit of this over a french press (in terms of taste) is that you can use a better filter than you use of a french press, that's all. So, I imagine it would taste quite similar to a Aeropress.
@@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.
This guy made brewing coffee 100 times more interesting (plus his reaction to when it worked was priceless)
Maybe a little too excited?!
But so many fails finally turned into success! Sometimes I can’t contain myself! Thanks for watching!
lets be honest every chemistry teacher seems to be astonished if something does what it is supposed to be :D

@@BealsScience ok will do.
nice work sir..
Thank you!
Ahhh this was great!!! Thank you for doing this ❤️
You are welcome!
Thanks for the kind comment!
I know I came in late, but I do have a question.
In the series it was mentioned that a consistent temperature was the key to a perfect coffee, in efforts not to get bitterness produced by high amounts of quinic acid levels.
Is this something real? The setup looks good but I do not see any thermometers throughout the process.
Temperature probes would take this to the next level for sure! I haven’t added any at this point but that will be part of the next one!
Awesome a scientist performing this. I've always used boiling chips to distill or reflux. Q : Do you think boiling chips will enhance the flavor? Maybe a bit safer.
Not sure but they may add a certain flavor depending on what you are using for chips.
Great vid! The link to the blog is broken btw
Can you tell me what link is broken? I will make sure it is fixed.
Thank you!
@@BealsScience The second one in the video description linking to instructions and supplies
@@coppurt THANK YOU for letting me know! I have fixed the website and the link so hopefully it will work now!
Thanks again!
A black lab coat? How does that work? How do you see if you've spilt something on your coat?
it'll start fuming and catch fire LOL
It will work best on H2OS or the other way around. So if no one creeches one will find out when it bleeches.
@@wernerhiemer406 What?
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 😁
genial video..
how about posting a part list of needed parts?
You can find all of the supplies here: www.bealsscience.com/single-post/2018/11/08/Brew-Perfect-Coffee-with-Chemistry-Equipment
What will happen if you use a vacuum so it boils at a lower tempreture ???
That is an interesting idea! The flavor of the coffee definitely depends on the brewing temperature so it could have an interesting effect, potentially beneficial, effect on the flavor!
Average high school chemistry teachers would be fuming right about now 😂 loved the video
Thank you!!
This is so great!
Thank you!!
This video gave me an awesome idea, someone should try to make the strongest coffee possible with soxhlet extraction.
That is a great idea!!
This was a fantastic video
Thank you!
This is frigging awesome!
Thank you for the kind words!!
I have a strange question, since coffee works, would loose tea work as well; was just curious because I've always wanted to make something like this in my kitchen for tea.
You can definitely use it for tea. You might just have to work with the timing for how long you leave the water in the leaves to brew. Let me know how it works for you if you build one!
@@BealsScience okay, I'll inform yeah on how it goes, thank you 👍😎
👍
It's alive!
you are awesome sir and make learning fun.
Thank you!!
I usually enjoy my morning coffee with a thick wall beaker (reserved for coffee only).
How long did it take to boil all of that water?
Not long-just a couple minutes. But I always start with preheated water so that it goes faster.
This video unbelievable amazing
Thank you for the kind words!!
does it actually taste better?
There is a difference! I think it really does taste better!
Love this! Was diverted here while searching for Gayle’s meth lab coffee apparatus in Breaking Bad. This seems a lot easier lol.
I’m glad you ended up here!
What type of coffee did you use
When I was experimenting I was using cheap grocery store medium roast because all my prototypes kept failing. Now I use coffee that we roast on our own! I’ve got a video coming soon that shows how to roast great coffee on your stovetop! And, it is legit good!
Thanks for watching!
I finally got the coffee roasting video up in case you were curious about the type/roast we use: th-cam.com/video/ahMBgH9icbY/w-d-xo.html
Is the boiling point of water the ideal water temperature to extract all the flavors present in the coffee grounds? Ive heard that slightly below 100C is preferable? Great video!
I read something similar at one point but can’t confirm the ideal temp. If you find more info, please let me know!
This concept is so cool! Hopefully you used new equipment xD. Very cool experiment.
Thanks!
All new and/or sanitized!
I'm curious how much oil content was lost through the steam. I might have to try out a steam distillation under vacuum once I can afford some brand new glassware.
That is a great question! I don’t actually know how much oil is lost, that would be an interesting thing to quantity!!
@@BealsScience once I get me some spare cash I'll take a crack at it. either that or I could rig up a makeshift soxhlet extractor and give that a go.
That would be amazing!
ok, that is cool. thx for sharing
Thanks for watching!
Lab Rule: No eating/drinking in the laboratory
Beals Science: I pretend I didn't know that, coffee is life!
what about coffee made using a soxhlet extractor
That would be interesting! I’ve got a soxhlet! What do you think we would isolate?
@@BealsScience probably a ton more caffeine
But how does brewing it this way affect the taste of the coffee? Also you should always use whole bean and only blend it right before you brew it because a lot of the flavor comes from the beans releasing a gas after being blended and boiled
It's not gonna taste that radically different from a french press. It's still just coffee sitting in hot water for a while that is doing the actual brewing. The vacuum is just moving the water around and the simple paper filter he rigged to the end of the tube is doing all the filtering. The only benefit of this over a french press (in terms of taste) is that you can use a better filter than you use of a french press, that's all. So, I imagine it would taste quite similar to a Aeropress.
I would love to see a set up meant for tea!
That’s a great idea! Any suggestions?
@@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.
Thank you for the ideas and info!
THAT! WAS! SO! COOOOOOOOOOLLLLLLLL!!!!!!!
THAAAAAAAAAAAAAAAAAAAAAAANKS!!!!!!!
You should use a magnetic stirring rod
So, does it do tea too?
Great question! I’ve never tried to brew tea with it. Now we must try it!
Damn fine cup of coffee
Agreed!
Reminds me of breaking bad when gale makes his coffee in the super lab.
