The Dangers of Disney

I was trying to find out who was currently leading the US presidential polls, when I got distracted by an item on Freedom of Information. That led me to this article. Isn't the internet wonderful?Inhaling helium to produce an amusing squeaky voice (a favourite game for children in the United States and Europe) may not be the innocuous party trick it seems, according to emergency medicine physicians at the Wesley Center for Hyperbaric Medicine in Brisbane, Australia (Annals of Emergency Medicine 2000;35:300-3).Simon Mitchell and colleagues report the case of a previously healthy 27 year old man who inhaled helium and subsequently developed a stroke with transient blindness and radio-graphic evidence of cortical infarction. However, the man had inhaled the gas direct from a pressurised canister, whereas most children who perform the trick - to imitate the voice of Mickey Mouse - inhale the gas from helium filled balloons.The patient developed rigidity and lost consciousness within moments of inhaling the helium. On arrival at the emergency room 15 minutes later, he regained consciousness but was found to have complete visual loss and evidence of cortical infarction.PubMed ArticleI still haven't found out who's leading, though...

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 much electricity is dangerous?

I found plans to make a device to give yourself a static charge using a negative ion generator. It outputs 7.5 kV and 10 mA. I've seen it in use and I know it's not dangerous. I wanted to build two of them together making it output 15 kV. Unfortunately that would also make it 20 mA. I'm not sure what the resistance of the human body is so I guess my question is will 15 kV and 20 mA flowing through a person be dangerous? Thank you for the replies and I'm sorry if this is a stupid question. I'm pretty new to my electronic hobbies.

Instructable censored for being dangerous

I would just like to comment about the fact that my Instructable on how to light yourself on fire (or how not to light yourself on fire) was censored. I understand that it is something that is very stupid and dangerous, but there are many things on Inructables that are dangerous and stupid (blowing fire, home made tasers, etc.) A lot of these things are also illegal. I just wanted to know exactly why mine was the one that pushed everyone over the edge, especially since it's so obviously a stupid thing to do. When I did it I was on fire for maybe 10 seconds, and the only reason I burnt some of my hair was because I was even more stupid and put the alcohol the whole way up my arm. What I really wanted was some comments on how maybe doing something like this could be made more safe, because there really isn't anything on the internet showing you how to light a part of yourself on fire. If you are into low budget film making it might be something people look into (I did) and if you can't find something you might do something even as stupid as I did. Anyways just wanted to defend myself a little bit. Alex

Is this dangerous? (Answered, thank you)

A friend recently bought a new house with an extremely large rural garden. While we were having a "tour of the grounds", her daughter found what appears to be a gun cartridge (pictured).  Thinking quickly, our friend handed the cartridge to me for "safe disposal". What is it? If I rip it open, what will I find? (It is about 70mm long, and feels hefty enough that it could contain lead shot.) UPDATE Thanks for all the helpful answers - pretty well confirmed what I thought I knew (except for the sabot!). I'll keep it safe and dry until I have time to dissect it with the boys.

But here, It says that Olive Wood is "Olive trees are extremely allergenic, with an OPALS allergy scale rating of 10 out of 10" aka "9-10 Extremely high potential to cause allergies, should be replaced with less allergenic species".

Dangerous Local Pest, What to do ? Answered

The bears and wild animals are moving into town because food is scarce in the mountains this year and our leaders admonish us for leaving garbage readily available and encouraging predation.    BUT this afternoon there was some confrontation at the fenced pen our dog uses for his duty and our dog was afraid to go out and chose to leave a large pile in our computer closet which I boldly managed to step into with both feet when starting the computer after supper.  Yes, I was prepping to do our monthly ledger but first I managed to drag brown foot prints over rugs through our bedroom to our bathroom.  After a couple hours of cleaning the most foul smelling dog poop, the monthly bills and Febreze treatment of the wall to wall rugs, we had to use a leash and collar to get our naughty pet to step out to the high fenced dog pen and let him discover it was safe ! ....  We watch preschool grand children and fear the situation.  What to do ?? ...

I was hoping to use flexible tubing to run the air but I doubt that would be safe at tank pressure. Would black iron and pipe tape be enough? Am I setting myself up for a world of hurt?

The bulk of them likely were replacements for systems moved into recycling or reuse.

Bunk Beds Dangerous for Kids, Hopefully Safe for Interns

A new report shows that bunk beds may be pretty dangerous things that can lead to broken toes, bloody noses, ceiling fan entanglement (!), falls, strangulation and more fun things. Thinking back on my own experience growing up on the top bunk as a kid and in school dorms, I think I can claim about three of those injuries. But it was fun and sometimes we combined the injuries like the time I pushed a kid off the top of a bunk (an accident, I swear) and as he was falling off he chucked a plastic squirt gun and nailed me in the forehead making me bleed all over the place.He landed on a cushion and I proudly went to the hospital. Good times.Well, here at Instructables HQ we have our own bunkbeds for interns and visitors and so far there have been no accidents. But, as this study from Nationwide Children's Hospital in Columbus, Ohio seems to say, it's only a matter of time before we add to the 36,000 reported injuries a year. Link

Hidden dangers of receips and dockets printed on thermal paper

Ever wondered how these thermal papers for your fax machine or supermarket docket work? Nothing that is printed by fast machines for you these days uses ink when it comes to cheaply producing a parking docket for example. If you played around with these papers you already know they turn black when you apply heat. A soldering iron at low heat makes a nice pencil on them... But what if you pet or kid loves to play with these papers? Often they like do just jast with the receipt for your fast food if found inside the bag ;) Most people would not consider a piece of paper as a health risk, but for thermal paper this can often be a different story. A lot of these papers still use bisphenol in one form or the other to develop the ink from crystal clear to black. Feel free to read up on it on Wikipedia - I recommend it! They also have more info on the thermal paper itself, including alternatives to bisphenol. Although recent studies are in favour of the thermal paper, when handled correctly some also show an increased risk for those dealing with a lot of paper - like the people working at cash registers in a really busy shop. Bisphenol can get into the body through the skin and by ingestion - for example when your kid tries to chew on it. As noone really knows where the paper you got came from it is a guessing game to figure out if it is free of harmful chemicals... So the best option is to avoid exposure when possible. If you know your kids or pets might to try eating some paper then make sure you don't leave any thermal paper around where they could reach it. But there is good news too as more and more countries try to set standards for thermal paper in regards to harmful chemical levels and protective coatings. Cheap paper for almost any priter out there can always be ordered from asia to avoid higher costs of local and safe paper though...

This made me wonder: If I use the wort that I strain out of my homemade beer, will the hops in the gooey mess still be dangerous to my dogs if they get into the compost days/weeks/months later?

Redneck Rollercoaster

This is called the Redneck Rollercoaster, but that's not quite the truth. This is an insane car mod that looks fun as hell and has the danger factor to bump it up to make it extra stupid. So who doesn't love some stupidly dangerous fun? Weirdos. Who loves it? Canadians.FYI, the guy on the left on the sofa is the driver. And how it works...

Why is "Danger is my middle name" filling the site with junky posts?

I get the intern stuff, but it detracts from the 'recent' material to dig through useless collection after useless collection of other people's work. Knock it off. And I  thought 30,000 K'nex posts were a waste of space.

Soooo... How 'bout that Cubic Zirconia, eh? [Most Likely DANGEROUS]

So I was just browsing Wikipedia when i fell upon the page about Cubic Zirconia. It turns out, that the basic principles of synthesis don't look all that complicated. So I was wondering, if anyone knew of any plans for a small skull crucible that were floating around the net.. I probably wouldn't use it for zirconiua, seeing as it needs around 2700 degrees Celsius to change structure (this is the dangerous bit), but it might be a fun introduction to induction heating. Also, it's a pretty awesome way of eliminating the need for a refractory when melting stuff (keeping a solid layer of the material as a shell instead). I think I could build most of the parts, but i don't know what frequency, how many windings and such would be needed for the coils. Also, if anyone knows of any other risks than the obvious burn hazards, I'd be thankful if you'd tell me before i go off and get killed trying to make this. Let's discuss! :D (Also, Skull Crucible is just about the most awesome name for anything ever).
