I can't get hold of any heavy water so I want to try extract it from normal water, I only need a drop or two. I was gonna use electrolysis to separate the atoms and increase the concentration if heavy water till it gets to around 70% (min.) but how much of power do I need to pass though the wires to only separate H2O and leave the D2O? (Need the deuterium for a fusor I'm building)

I had a bunch of fresh herbs, and some home-distilled 180 proof alcohol that a friend brewed. SO, I thought I'd try to make some smelly stuff. I packed a jar with the fresh herbs, and filled it with the alcohol, plus a little tad bit of water. I let it sit for two weeks, and now it's ready to be strained. BUT, I'm not sure what to do with it. Do I use it to make a perfume, room spray, body spray? Can I use it to make an essential oil? Is what I now have called an herbal extract? One jar is fresh sage and rosemary, Jar 2 is rose geranium leaves and rose petals, Jar 3 is lemon verbena, and Jar 4 is lavendar and sage. All advice is welcome!

I hear oil from algae is extracted by drying it, then soaking it in alcohol to dissolve the extract, then straining it and evaporating the alcohol. I might start experimenting with that, but any suggestions?
Question by sherlocksbumstead 9 years ago | last reply 5 years ago
I am currently looking to build a system that will allow me to boil medecinal mushroom under pressure. Why you ask? Because studies have shown that high temp under normal pressure will destroy the chitin( the building block of mushroom as opposed to cellulose for plants), but will also destroy most of the medecinal compound. What is needed here is a system that can sustain pressure of around 55 psi minimum. My first guess is to get a pressure vessel that can whitstand more than the required 55 psi in order to limit the risk of failure and explosion. See an example here ; https://www.ebay.com/itm/Alloy-Products-Pressure-Vessel-Tank-135PSI-100-F-w-McDaniel-Gauge/183110238087?hash=item2aa2387f87:g:0DUAAOSwbmFanWiEI do not need more than 1 liter for the pressure vessel but it seams that they don't make them smaller than a gallon. Now the big question is, how do I get the water boiling using one of those tank? I can't just put it on a stove! But if you know of something can could safely reach 55 psi and go on the stove please let me know.Also I was wondering what keeps the pressure inside the container? Does it need a water pump to maintain pressure by pushing more water in the vessel or does it merely builds pressure with steam until it reaches his capacity?Thanks to anyone who's willing to give me some pointer, I truly appreciate.

Have you ever wondered how to do something in batch that someone has already done and wrapped it nicely in a little .exe file? Some people like to keep their batch programming secrets to themselves, and don't want to share, so then convert their batch file to .exe. But you can't discover their secrets if they have converted it to .exe, because all you will find is gibberish. Before I will tell you how to "unextract" an .exe, you must now how ".bat to .exe" programs work. What they basically do is "wrap" a batch file with an executable; think about a Christmas present. Pretend the gift inside is the secrets of the batch file, and the wrapping on the outside is like the executable, which prevents you from "seeing" the secrets inside. But this is no ordinary present, the wrapping on the outside can not be torn or opened, you must press a button in order to to "unwrap" it. But when it "unwraps", it shows you what it is, but hiding the secrets. If you couldn't fully understand that, here is what actually happens. Try to compare the two.Batch files in executable form cannot be viewed as the batch language. If you open it in notepad, you will get a whole bunch of symbols. In the philosophy above, pressing the "button" is the same as opening the file as an executable. It opens just like a batch file, but if you try to edit it, you won't be able to read it. What the executable does, is temporarily extracts the batch file within it, to a temp folder.Now to the "how to" part. Here is where that "temp" (temporary) folder is: %userprofile%\Local Settings\TempNow all you have to do is copy and paste that into a windows explorer address bar. You will now be in a temp folder where the batch file will be dumped. Now you have to run the .exe file. But now you do have to get your hands dirty (virtually!). Search in each folder till you find a batch file, most commonly called batchfile.bat. Simply right click, press edit, and your in!So that's how to "unextract" a converted batch file! (note: I didn't make it an instructible because, well, no one likes a one step instructable!)Good Luck!

I have a couple of battered old car batteries. There is no local scrap dealer that will take them so I was wondering if it would be possible to extract the lead myself and sell it for scrap. I have searched on google and cannot find anything about this and I suspect it would be dangerous and impractical. However I thought there's no harm in asking here. I was imagining that I could open the battery up and pour the acid into some kind of strong alkali, neutralising it to make it safe for disposal. But then, I certainly wouldn't like to try this without some advice first. Cheers! Pete

Question by tylervitale 7 years ago
OK, so the main ingredient in instant hand sanitizer is ethyl alcohol, which is a perfect fuel for a soda can stove. I have tried using the sanitizer straight but it leaves to much goo behind. When stalt is added to the hand sanitizer it turns it to liquid and leaves white floaty things in the liquid(glycerol?). These can be filtered out with a coffee filter. This leaves a more concentrated solution (which still dosnt burn well) and it has salt in it. What I want to know is how I can extract the alcohol to at least 80% concentration. I don't have a still (and dont want to make one). Any ideas?

Hi I'm just in the process of refurbishing the bathroom of a flat I bought. It's all been plastered out already and I realised I've no extract! So, I created a plenum at hi level and mounted a fan under floor and have ducted it out. I want to run the small AC extract fan 24/7 at low speed (kinda tick over speed) and then switch it to hi speed when either the humidity goes up (cos the shower is running) or the light goes on (assumes someone's using the WC!). I can't get to the lighting wiring so I'll need to sense that remotely. I can fit a humidity sensor in the duct work. I've tried everywhere to find something suitable with zero joy. Is anyone here able to point me in the right direction?

Can I use white rum to make vanilla extract instead of vodka?
I'm attempting to create a content pack for a Minecraft mod, and need old gun sounds. Anyway, I remembered an older game (not DOS era) game, Oregon Trail, and thought I could rip the sounds out of it, since it had some nice gun sounds from the hunting sections. Anyway, usually this wouldn't be a problem, but that's only if the sound files are either .wav or .raw (which I can expand using audacity), but ... well... as you can see, I don't have anything to work with here. If someone can point me to the proper file, I can probably extract the sounds from there (I have another windows PC I can use if necessary) Note that the folder labeled "CD" is a direct copy of the game CD.

Question by AlternateLives 6 years ago | last reply 6 years ago
This question could go under both "Health" and "Pets" but I chose this one as the most relevant. I drink alot of different types of tea (black, green, red, white, herbal, you name it) so I have alot of supply around. And recently my poor little kitty was diagnosed with a cancerous soft tissue sarcoma in his hind leg. One of the many things our Veterinary Oncologist has suggested to us is supplements of green tea extract daily (as it has shown positive influence in human studies of survival rate with different types of cancer). It wouldn't hurt to give it a try. So the more detailed question here is, how can I make my own concentrated liquid green tea extract without over steeping the tea and breaking down the molecules of the beneficial antioxidants? And as far as dosage goes I have a general idea of how much extract to give (about 30 mg per day) if it's pure (like in a drugstore capsule). Any thoughts or ideas would be appreciated.

I have been reading about the subject, and most articles tell that carbon filters are good for solder chemicals, fumes and odors, while HEPA filter are designed to remove dust, allergens and micro-organisms from the air. Supposedly, solder fume extractors should use both filters for an efficient filtering of the chemicals. Is this correct? Thanks for your time!

Anyone have a good way to extract a broken phillips bit from a screw head? It's the common #2 phillips head. The screw is a #10, stainless steel. When I was driving it in the bit snapped off so that it fills the slots in the screw head. I've tried picks and punches but it's still stuck in there. The screw is countersunk and it's in cosmetic wood (can't dig it out). I can't drill it and use an easy out because the bit is too hard to drill. To make things more difficult, the screw is inserted upward and the piece is a railing so it isn't movable. If there is a better forum for this question please let me know.
