Various experiments done in my home laboratory, which is a fun and fulfilling hobby for me. I try to come up with interesting experiments that will help raise interest in science, since schools these days aren't allowed to show the more exciting reactions in classrooms. I also try to show the full process of chemistry, not just the reaction. That way I hope to give viewers a sense of what chemistry is really like, and deal with important topics like proper disposal.
Kaowool Furnace Build
In this video, I take you through the process of building my new furnace from scratch. I chose a kaowool furnace because they are very simple to build and very lightweight. Total cost was about $390, and $300 of that was in the custom welding. So if you know how to weld, this furnace is incredibly cheap to build.
This furnace is INCREDIBLY well-insulated. After the first use seen in the video, it was still too hot to touch the interior after FOUR HOURS! The exterior was just warm. It also heated up to aluminum melting temperature very quickly. I'm very satisfied with how it came out.
The mason jar mixing system was inspired by @PaulsGarage.

Dude save your grill for hotdogs ! Theres no way your charcoals are hot enough to melt copper! Lol but hey back to chemistry school!
😢
Can it be ignited by a match or a fuse?
is it the same as red copper sulfide
No, copper sulfide is just CuS.

Use a scrub brush while your washing it down to remove the air pockets
so, i have a bottle of chlorine bleach crystals. is that more useful for this?
Different chemical, unfortunately.
How dangerous is it handle the rocks? It seems like mining them could be scary, since they are out in the rough with many opportunities for dust formation.
Why do people interest themselves in other people's business. he's outside
Well done capturing this first experiment on video and achieving some melt. I love how every back yard melter invents a slightly different setup based on what's lying around😁. I've been using an air mattress inflater with limited success, I need a hair dryer!
unfortunately pressure plays no role in the production of crystals which would be more interesting in weather forecasting!
could you make a video of this mixture when dropped into bottle of water, will it still react
Looks like you're breathing great air quality being around that😢
Can methyl orange be used as the indicator?
Depends on what you're titrating. Different indicators change colors at different pH's, some are more suitable for certain acids than others, etc.
So, doug, do you ever revisit your old channel?
Where’d you go D: I ran across this channel about a year 1/2 ago..as someone else said, I’ve come back many times to re-watch certain things. Hope you’re doing well, you’re easily one of the best on YT in regards to breaking things down into laymans terms, which for those of us with only a minor background in chemistry, makes a world of difference and helps one understand things we probably wouldn’t have caught onto otherwise. Hope you’re doing well, come back!
Thank you so much! I really appreciate the comment and compliments. I've had a rough couple years, and haven't had the time or energy to keep up the channel. Things are much better now, thankfully, and it would be fun to get back into it. Your support really means a lot. Thank you.

Does the slag all sink to the bottom or how can I skim it off the top?
Everything floats. I just use a metal spoon to skim it off. Aluminum benefits from a flux, otherwise the dross gets pretty gooey and hard to separate.
Epic
Can this work with other metals like copper, brass, or gold?
It might be able to get up to copper temperature as-is. It could really use some improvement to hold heat in, though. Maybe wrap it with rigidized kaowool or surround it with fire bricks. Also you'd need a better crucible - mine failed after a couple melts.
I get people not wanting to hear others harp about safety but from experience, when you least expect it some accident can happen an it Will melt your flesh of your foot all the way to the bone. Better safe then sorry.
Just kinda curious say what if ya boost your chloride say add some salt can street salt work or does it have to be no salt
What brand of container is that ? All of the similar containers i can find all have slanted/tapered sides . Thanks
Sterilite!
@@mrhomescientist thanks , not doubting your response but every sterilite i have got and every one on their website has tapered sides . Maybe yours does too but the camera makes it looks straight sided ? Not that i really care , i was just curious . In the process of building an h14 flow hood , so my glove box days are over . thanks for the response just the same .
Dear NSA This Is For My Criminal Science Class
I always wanted to work for the FBI! Now I’m on their list 🖤
From 2024. Remember: chlorine gas reacts with an aqueous solution of sodium hydroxide and the first products are sodium hypochlorite and sodium chloride, while temperature raises. So heating a solution of sodium hypochlorite allows the inverse reaction: NaCl + NaClO -> NaOH + Cl2 (1). Even if you have a pure NaClO solution the following equilibrium exists: NaClO + H2O <-> NaOH + HClO (2) and very unstable acid 2HClO <-> 2HCl + O2 (3) and HCl + NaOH <-> NaCl + H2O (4). So every conditions for (1) are present. Perhaps it's more effective dropping a concentrated sodium hydroxide solution.
Please help me 🙏 I'm confused in the distillation method, Exactly when taking pure substances I deliberately used a sample of medicine that had 5 ingredients in it, after I finished extracting it, then I filtered it and got the residue & filtrate. But I'm confused about how to separate the purity of these substances using the Distillation method, even though I have recorded the boiling points of the 5 substances, here are the boiling points: Substance A > Boiling point: 400 °C Substance B > Boiling point: 260°C Substance C > Boiling Point: 379 °C Substance D > Boiling point: 520 °C Substance E > Boiling point: 232 °C For example, if I want to get the purity of substance B, how do I do it ?? 🤔🤔🤔 Who knows, someone might be able to tell, 🙏

To be fair fbi, i was just curious on how to build this in a safe and controlled environment just for funsies, please dont swat me😢
IDK if you know this, but the HEET in yellow bottles is IPA. HEET in the red bottle is methanol.
Agno3 + h20 + cu = Ago + Cu(NO3)2 + H2, so it's not pure silver but silveroxide
It is not the best to use ammonium nitrate because there is a bit of ammonia in the end product. I was using ammonium nitrate and after a day or two there would be a white substance at the bottom and I am assuming this to be ammonium nitrate I think. I switched to potassium nitrate because of this.
Not the best idea to be bare foot when handling hot metal .
Pretty cool man!!
um thats not slag in the cup its your aluminum you waited to long to pour out
Bear feet not smart
Can we use sodiumbicarbonate on the place of sodiumbisulphate

Can you use acetic acid instead of nitric acid
perhaps you can use swimming pool chlorinator, it comes as a powder. Not sure if it’s pure NaClO3. Also bleach comes with a small amount of sodium hydroxide, presumably to offset the chlorine in the water turning into hydrochloric acid. Probably irrelevant with all that sodium chloride present.
Melting aluminum bare feet. This guy has no idea what he is doing. I worked in a bladesmith workshop, and as far as I now, one can never be too cautious around high temperature metals.

If the lithium caught fire in your glove box you could say goodbye to your glovebox. The temperature of a burning lithium battery is said to be at 500 degrees Celsius. It burns intensely and very quickly, and will have no trouble burning through the plastic box. With little experience, I opened up a lithium battery in open air. That was my first mistake. I knew nothing about what might happen if the battery was shorted, but that's what set the battery on fire while I held it in my bare hands. In the split second it took for me to react and drop it onto my workbench, it burned the part of my thumb that was in contact with the coated film. The iron disulfide electrolyte coating can spark when in contact with metal and it will catch fire. I was not using tools, so I imagine the spark was set off when the electrolyte came into contact with the metal (copper or aluminum?) foil inside the battery. Chalk this up to experience. I now know how dangerous these batteries can be if improperly handled. My thumb was fine and the incident left no visible damage by the following day, though it hurt like hell for the first few hours after it happened. What surprised me was the speed at which this happened! So, be safe. Be very careful when working with these types of batteries. This is not to say, I wouldn't do it again, but I will take better precautions the next time 'round.
