Electroplating chemical mishap

I figured it would be cool to quickly electroplate some stuff. Since I was lazy, I only used what I had on hand [block of zinc, vinegar, muriatic (hydrochloric) acid)]. The zinc ingot was taking too long to dissolve in the vinegar, so I added about 30 mL of hydrochloric acid. A couple hours later, I was electroplating fine. After two weeks of normal zinc chloride electroplating, the acid suddenly took on a nasty dull brown/yellow amber shade and a ton of white bubbles formed around the zinc (still in the acid). Can anyone tell me what happened?

Q: Is there any chemical that one could mix with water to make the solution more diffuse/milky that helps the transmission of light in the fluid and also helps the diffusion? Since a fluid being backlit would change in temperature there might be some cool things one could do with that, a light panel that changes visual properties over time?

which chemical to deactivate microchips? Answered

Hi, I'm making a cryptex, such a thing like in the Da Vinci Code, and I'm going to make an Instructable of it later. But I'm going to hold USB-sticks in it instead of a piece of paper. That's a little more modern nowadays people lose a lot of usb sticks with secret important information so I'll use a cryptex for it. The crpytex like it was invented by Da Vinci contained a paper, which was rolled around a tube with vinegar in it. If someone decided to just smash the cryptex, the tube breaks and the vinegar would destroy the ink on the paper, making it unreadable. I don't think that works good in real but I don't think it will deactivate a usb stick either. So I want something else in the tube that DOES eat the chip. So I'll remove the outside wrapping of the USB-stick. What fluid can I use?

Avoid using PVC

I see a lot of projects that use or re-use different grades of PVC pipe due to its easy use and availability. Free or cheap PVC seems to be a good material choice for those who lack the tools and skills needed for metal or wood work. I suggest that builder rethink this choice. Exposure to PVC is dangerous to your health. Fumes and dust from cutting, drilling and accidental burning or overheating PVC are known to cause cancer.A few points:PVC production is the largest use of chlorine gas in the world.Chlorine production consumes enormous amounts of energy.Chlorine production causes mercury pollution. Hazardous by-products are formed throughout the PVC lifecycle.By-products of PVC production are highly persistent, bioaccumulative, and toxic.PVC is extremely difficult to recycle.PVC is one of the most environmentally hazardous consumer materials ever produced.source: grades of PVC have different melting points, flash and glass temperatures. At 70-80 Degrees C (~150 F), most grades begin to soften and degrade in performance. This should be taken into account when building projects that involve any kind of direct or indirect heat, including hot water, etc.(I've edited this post to contain more useful information)

My Chemical Romance Update =D

My Chemical Romance will go on a temporary break while they seek inspiration to write a new album."We can't make any more music unless we live. When we get a chance, we're going to get together and do some demos and start rolling. But we're going to take it slow,” frontman Gerard Way said.The band took two years to tour in support of their last album, 2006’s The Black Parade. {Posted from The Star}Things have been a little quiet since My Chemical Romance killed off their alter egos, The Black Parade, back in may at New York's legendary Madison Square Garden venue. However frontman Gerard Way has posted a massssiiiivvvveeee update answering all your questions about the new album, how drummer Bob Bryer is after recent wrist surgery, how guitarist Ray Toro's wedding went, what Frank Iero's been up to with his side-band, Leathermouth, as well as quashing internet rumours that he recently died in a car crash.It reads as follows:"Hey guys, Gerard here... I'm hanging out with Mikey in New Jersey, relaxing, drinking coffee, talking comics, and getting ready to take a drive down south tomorrow. I don't know what states I'm passing through but I know where I'm heading. Don't worry, I've got a the Clockwork Orange audiobook, a Dr. Pepper air-freshener, and a GPS so I don't get lost. We figured by now everyone that's a fan of the band might be wondering what we're up to, what we're planning, so I thought I'd write this letter and fill you all in."We're living, decompressing - The Black Parade took over two years to tour and six months to make so that's a lot of existing in a fictional world, and we're just extremely happy to live in a real one for a while. One thing I can let you know is that we're excited. Genuinely more excited than we have ever been to be in this band, make some new music. And we have ALL been writing new material in our own separate worlds... I started a week after I got home, buying a good rig, an old Jag, and a bunch of pedals- just searching for the next sound."Bob is recovering well from his recent wrist surgery - exceedingly well considering how risky the procedure can be. We're all really happy that when he picks up the sticks again he won't be in the intense pain he was in during the last year of touring. It's going to take him a while to rehabilitate but knowing him, he will most likely be playing the drums before the doctor says it's a good idea. He just loves playing, we all do. Franks on the road with Leathermouth and Reggie and The Full Effect so you should go see them and get spit on. I know Leathermouth doesn't have a record out yet, but Frank gave it to me in Mexico and I can easily say it's my favourite post-hardcore record of the year, so I know you will at least enjoy the songs if you don't know the words."One of the best parts of the last five months was getting to see Ray get married and all of us be a part of the wedding. It was beautiful. I'm not sure where the happy couple is right now but I am sure wherever they are, they are really enjoying it. I have never seen him happier in my life. So we made plans to get together soon and make some demos, see where our heads are at, take it slow. If explosions happen in our heads right away who knows how soon we could have a record out, we aren't in any rush but we get just as anxious as you to find out what the next 'thing' is going to be."So that about wraps it up... I'm glad I could stop by for a chat, I think I will do it more often. I'm writing more comics, writing more music, and missing my wife right now. Oh, and I heard a rumour that I died in a car accident. I didn't."[{Posted from Kerrang!}]

How do I clean a 55 Gallon Plastic Drum that contained Industrial Grade Detergent?

I picked up three free 55 gallon plastic drums after seeing them posted on craigslist.  I was inspired by the compost tumbler and rain collection instructables, and I was looking to build my own.  However, the plastic drums contained an industrial grade detergent used in food and beverage processing facilities.  Two of the barrels were FiChlor Foam HD and the other contained Liqualin CC.  Do you think I could clean these out enough to make them safe for these projects?  Would the chemicals have leaked into the plastic? For rain collection, I was going to use the water for flushing my toilet, so it wouldn't be for watering a garden, and definitely not for drinking.  For the compost, would the chemicals remaining in the plastic leak into the compost?  And then would any plants exposed to that compost die? I really appreciate some feedback on this.  I've read most instructables on here that involve 55 gallon plastic drums, and the recommendation is to use Food Grade containers.  I'm just disappointed about the possibility of not being able to use the ones I picked up because they contained a detergent.  The containers are marked as "Corrosive" and "Do not reuse this container unless it is first professionally cleaned and reconditioned."  This is definitely a bad sign. :( Thanks guys, Eoin Here's some information I found from the manufacturer, Chemetall: Safety and Handling Precautions: Oakite FiChlor Foam HD is a highly alkaline chlorinated material containing sodium and potassium hydroxide. Direct contact causes irritation of eyes and skin. It is harmful if swallowed. Avoid contact with eyes, skin and clothing. Wear safety goggles, rubber gloves and other protective clothing when handling. Wash thoroughly after handling. Avoid breathing vapors. Use only in well-ventilated areas. Do not take internally. Liqualin CC:  Heavy-duty, low foaming, non-silicated alkaline liquid for use in CIP systems or spray washing stainless steel processing equipment in beverage and food plants.

The more natural way of cleaning things...

At my workplace we basically have a specific cleaner or cleaning product for every task you can think of. From glass over stainless to plastics and desinfectants for lots of different surfaces. After a quick look into my cleaining cabinet at home I started to wonder if I am doing something wrong as I only have a few cleaning things for my use. Asking my friends also showed they have a big bunch of cleaning chemicals, plus the bottle of bleach that everyone down here has. So I though: Your grandma only had a few cleaning products and you learned most of things you need to clean from her. Considering I grew up healthy I guess she must have done something right.... Let's clean up with the cleaning myths, shall we? 1. What cleaning chemicals do you have? For quite a few people the list would start something like this: Dishwashing liquid, window, cleaner, bathroom cleaner, soap scum remover, floor cleaner, oven cleaner, several desinfectants.... If that is true for you too than we might be on to something already. 2. What cleaning chemicals do I really need? This is a good question as everyone is a bit different but I assume a healthy household here. Of course we need certain things to clean our various surfaces properly but it is far less than waht you have been told by the TV commercials.... These days we like to think if there is a special cleaner for something then of course we have to use it to clean properly. Unless you have trades people walking through with their wet dogs several times a day and see dust storms at least twice a week you really only need a few things. So let's get to the basics: 3. Old style cleaning and what you need for it - really the only stuff required to keep all clean and sanitised. a) Methylated spirit b) Clear ammonia - cloudy ammonia works too but be aware that the added soap can be a problem that leaves streakes c) Hydrogen peroxide - pool grade to be cheap in the long run d) Orange oil - citrus oil works great too if you prefer a different smell e) Soap - just basic soap, these stinky, slightly yellow and hard bricks - no fancy smelly soap ;) f) Several cleaning brushes but you should already have those g) Windows cleaning tools - the basic microfibre cloth and squeegee will do h) Several microfibre cloths - bigger ones for floors and walls, smaller for windows and the rest I) Yesterdays newspaper j) Baking soda With those few things we have everything to clean whatever comes up and if bought in bulk comes down to a few cents per bottle compared to a few dollars when you buy all the stuff you don't need. Lets figure out what the stuff does and how to use it: 4. Mixing and what to use it for.... The alcohol is a really good remover for everything greasy and also desinfects the surfaces. A quick spray and wipe on your bench is all that you need to remove oily residue or the mess from the kids. Mixed with a bit of soap and water (about 50-50) also removes sticky stuff like jam or syrup. If we use about 50ml of alcohol, 50ml of clear ammonia and 900ml of water we get one liter of really good window cleaner. The modern way is to use microfibre for the cleaning and a squeegee to get it dry, the old way just uses a cloth and then the window is "polished" with some old newspaper. The black ink reacts with the alcohol and form a mild abrasive while the paper soaks up the moisture, the result is a prefectly clean window in under 3 minutes. Orange oil is not only a powerful degreaser but also lifts old dirt or even glue residue. Used directly it will get rid of the remains from sticky tape, stickers and everything that other cleaners fails to get off - smoth surface and non soaking of course. 50ml of it with 50ml of ammonia and 100ml of alcohol per bucket makes a good florr cleaner and your house smells nice when done. Works best if you can use a microfibre cloth or floor wiper to dry the surface with it. In the kitchen we can find a lot of surfaces that are greasy and we already covered that bit, so lets get to the though stuff. The kitchen sink can become dull looking although it is not scratched. This is due to hard water, food residue, soap and other things. Best is of course to wipe it and dry it after use but who really does this every day? A pot scrubbing pad with some baking soda on it does the trick here. Make the pad nly moist and sprinkle the baking soda on it. Rub over the stainless and if too dry add a few drops of water. Once done rinse off and enjoy the difference. For hard to clean or badly turtured sinks you can try a ball of aluminium foil and coke - use it like a polish. The oven is often our worst nightmare. The cooktop is not far behind. But even here we can have a chance to clean without too much hard work or bad chemicals. Of course the best way is to prevent these spills and boil overs ;) For the cooktop some hot water and baking soda will soften the baked on stuff. Simply remove what you can with the hot water and then sprinkle the surface with baking soda. Cover all with the paper towels and if not wet enough add a bit more hot water so all shets are soaked. Leave ove night and wipe clean the next day. The oven is a bit of a problem once the side and back wall are filthy. If baking soda with a pot scrubber won't do the trick get some of these steel pads with soap in it. The soap in them is special in terms that you only need a little bit of water to remove almost anything with them - and they won't scrath enamelled surfaces. On the bottom we often have badly burnt in things that are next to impossible to fully remove. I suggest to cover the same way as the cooktop but also to add some orange oil. Just make a thick paste of baking soda and orange oil and wrok it into the soiled surface. Cover with wet paper towels and leave over night. Now you don't want to flood your oven, so that means you need to use a sponge or thick cloth that is big enough to wipe off the surfaces you soaked the day before. As the orange oil really is oil it pays off to use some alcohol in the cleaning water to get rid of the oil and grease a bit easier. Don't expect to see a clean and shiny surface after one treatment if the oven was badly misused, you might have to repeat the procedure a few times. If in doubt use the soapy steel pads for last clean and before soaking over night again. Three to four treatments are usually enough to clean even the worst disaster that can happen in an oven unless you baked it in for months... 5. Desinfecting and mouldy spots.... As said, the methylated spirit is basically just pure alcohol and kill almost anything that might harm you. But sometimes that just is not enough. And who really wants to spend an hour or longer to clean some mouldy spots in the shower or try to cover the smell by spraying room freshener? As a lst resort for everything I use Hydrogen Peroxide. The supermarket grade is only 3% and usually badly overpriced, so I suggest to get a small canister of pool grade peroxide. Do yourself a favour and ask them to install a tap on it - you don't want to do it yourself unless you already know how bad pool grade peroxide is! For your own safety when handling it I strongly recommend wearing long rubber gloves, nitrile is better but please no latex as it could start to burn when getting in contact with the peroxide. For high grade desinfecting or the removal of mouldy areas I recommend to dilute 1:5, one part of peroxide to 5 parts of water. Only for the mould removal on tiled, plastic, glass or metal surfaces you can use the peroxide pure from the container - but please add face protection when cleaning! Some spray bottles work with peroxide some just start leaking badly, if you want try an old bottle of chlorine based cleaner after really flushing everything out. The peroxide breaks down any organic material it comes into contact with, so not just the mould you want to remove but also your skin or eyes if you allow contact. On the skin you see white areas after contact and they won't go away until all the oxygen in the skin is gone that was left by the peroxide. If you act too late it means you might loose some skin flakes. The sure sign of overlook exposure on your skin is a burning sensation in the area - this only happens when the amount was big enough or your clothes got soaked. On your surfaces to clean you will notice bubbles forming quite quickly - this mean the peroxide is reacting with something, usually organic material. Let it bubble... Once it stops bubbling the surface is either sterile or the peroxide is used up, if it bubbles when adding fresh peroxide onto it then there is still crap left ;) It really helps to brush off the surface after each treatment as a lot of loose material will be flushed out when rinsing off. Once it looks and smells clean again it usually means it is clean :) 6. Special case: Wood... Be it wooden floorboards, furniture or just your chopping board - always try what the manufacturer recommends first! Untreated wood should never be cleaned with anything wet! Sealed wood, like floorboards or things with varnish on it to make it water proof can be cleaned the same way as mentioned above - but I would leave out the ammonia as some wood treatments simply won't tolerate it and might go dull instead of returning nice and shiny - spot testing required if you think you have to use ammonia as well! Orange oil itself makes a great furniture cleaner if the surface is smooth and sealed, but if it is not it means the oil soaks into the wood together with the stuff you want to clean off! It also takes off several paints and types of varnish if you work it hard enough and give it some time, so avoid this and be quick instead of forgetting to finnish the job ;) Always try to wet the surface as little as possible and wipe fully dry as soon as possible! Ok, good start but what is the real benefit? For me the actual benefit is that I know what I am using and exposing myself to. Just reading what is in most cleaning products we find at the supermarket makes me want to clean again after using them, just to remove their residues... I admit it might take some time to get used to mixing and just having a few ingredients for the cleaning but it does work great. Especially if you or your kids are already sensitive to certain chemicals or just of poor health in general you might see the benefit quite quickly. Some people really don't like the smell of ammonia but unless you are sensitive to it there is nothing to worry when using the household grade as we always dilute it down massively anyway. A good way to avoid the worst stink is by mixing it outside with the wind from behind. I won't say that certain commercial products are bad, harmful or not good enough for the job. Some are actually worth to have in some cases but I just say it is better to only have a hand full of chemicals that are not too bad instead of an endless list of things were we don't even know what's inside. For me the best is your surprise when it actually works better than you expected and report your findings here.

How do I thin out 2-part epoxy?

I'm wanting to make some micarta-like material, using two-part epoxy and paper. I've done a test run, and the material was rigid after it had cured for a few days, but didn't cut like I hoped it would, because the epoxy didn't penetrate the paper. Part of the issue was that the paper was coated, but I'd also like to thin out the epoxy some so that it will soak into the paper better. I'm inspired in this endeavor by these two instructables: The epoxy I'm using is 3M Scotch-Weld DP-190. The label says it contains epoxy resin, polymeric diamine, kaolin, and carbon black. The complete MSDS is here. This is what I'm using, because it's what I have. Got a case of these two-tube dispensers cheap at a yard sale. :-) So, what can I use to make this more liquid? Right now the consistency is a little bit thicker than honey. It doesn't spread out when applied to paper, and doesn't soak in at all. My limited knowledge suggests that toluene, listed on the MSDS, might work, but I'm hoping for something a bit less volatile. I'm aware that whatever I do is likely to extend the curing time, but that's not necessarily a bad thing.

Can chemical based projects be posted on instructables?

 I know there are projects with more hazardous components but I just want to check before I post something.?

how do I build a chemical car?

Hello, my name is Taylor Love. Right now my school is having us do a science project where we need to use chemicals to propel a toy car across the room. sounds easy right? oh wait there's a catch. no combustion reactions, or explosions. :( got any ideas besides the usual baking soda and vinegar trick? any help would be great. if anyone knows how we could make a battery powered car go across the room, that'd be pretty cool too. but we have to make the battery from scratch.

What changes in milks taste chemically as it turns? Answered

I'm not sure what to look fo or I'd just research this myself but: I like the taste of milk that has sat out long enough to get the smoother creamier 'warm milk' taste but not so long as to actually start going off.  (twixt 15 minutes and 30 minutes depending on room temp) What I would like to know is why it changes.  I know it has something to do with the bacteria in it changing it somehow but I don't know how.  Am I tasting the bacteria or some byproduct of their breakdown of the milk?
