what makes bleach so strong | To make bleach, a direct electrical current is sent through a sodium chloride solution (table salt and water). This basically splits the atoms leaving chlorine and the caustic soda. Both chlorine and caustic soda (lye) are extremely dangerous. These two chemicals are reacted together to create what we know as bleach. | Bleach contains very harmful chemicals that can easily cause second degree chemical burns if the product is being used in a concentrated form. Adding water to the product could reduce the hazardous nature to a great extent by diluting the product. | eng_Latn | 21,900 |

what is nail polish made of in china | Nail Polish. Nail polish is a cosmetic product that is used by most women across the world. It is not simply paint as applying paint done on wood or an automobile would be hazardous for human beings. Nail Polish was invented thousands of years ago in China to provide shine and color to the nails using different products such as egg white, wax, vegetable dyes etc. The shade of the nail polish signified the status of the person, with a darker shade implying a higher status in the society. | All Deborah Lippmann fashion nail polishes are infused with treatment benefits from ingredients such as biotin, green tea extract, and aucoumea. These formulas are long-lasting, dry quickly, and apply evenly while high-quality pigments ensure eye-catching flash. | eng_Latn | 21,905 |
Is it possible for Superman to have sex in a red sun chamber? It is quite obvious that if Superman had sex with a normal human, he would kill them. Therefore, I think the only way possible for him to have sex is in a red sun room. Has it ever been shown or mentioned in the comics? | How have Superman comics dealt with the Man of Steel, Woman of Kleenex problem? When I was a teen and Superman II came out, when Superman realized he and Lois were in love, he de-supered himself in the Fortress of Solitude so he could be with Lois. Right after he emerged from the crystal cage that drained his powers, the first thing he does is take Lois' hand and escort her to a conveniently placed bed that we had never seen there before. This implies it was necessary for him to lose his powers so he could have sex with Lois. The problems involved in this situation are well covered in the wonderful essay by Larry Niven, . But I also know that Superman has been in the comics for decades. A friend of mine once said, "Oh, he tells her who he is a lot, but he always makes her forget it again later." So how have the comic books (since this is Superman's primary medium) handled this? Were there different ways it was handled, or was it always handled the same way? Have they literally kept Superman and Lois from having sex for decades? Or have there been times when they've ended up in bed together? How do they deal with the issues of the Man of Steel having sex with, and not killing, a woman of Kleenex? | Do spice containers need to be hermetic? Spice containers purchase I'm planning on upgrading my spice storage. Reading some advice online (e.g. , and ) I came to the conclusion that spice containers should: Not be exposed to direct sunlight and high temperatures Be airtight Which means that either you store it inside of some closed cupboard/wardrobe/room or you have containers which do block light and are in a relatively shady place. And the containers need to be airtight. Available solutions I've been browsing for some containers available online in my country and the 2 most sensible options I've seen are these: The problem The first one is hermetic (it has some rubber around the lid) but it's clear glass. The other one does not have the rubber, just a regular twist-off lid, but it's amber glass. It'll be hard for me to find any space inside of cupboards to store all of my spices (I need at least 30), so I'd rather buy amber glass container, which I believe will effectively block the sunlight, even when kept on the counter. But I can't find any hermetic amber-glass containers, only ones with regular lid. The question Is that regular twist-off lid enough to keep spices airtight and fresh? Or should I focus on buying a hermetic container (like the one in clear glass). I could then for example paint them black to block the sunlight. | eng_Latn | 21,906 |

Copper Bond Epoxy is THE BEST...except for | I would give this Copper Bond Epoxy 5+ stars if it weren't for the container. The epoxy itself is the absolute best epoxy I have ever used, hands down. However, I have always hated these stupid syringe containers that are 'supposed' to eject the two parts of the mixture evenly. The two parts have a different viscosity, therefore, one side runs out while you're pushing your guts out to get the other side to come out. I have to say, when the tube is brand new, this is not as much the case, but if you have used a little bit of it and then cap the ends, the next time it is used is when it starts getting bad. What eventually happens is the two halves of the syringe are completely misaligned with the material in the tubes, so you end up wasting a lot of epoxy just to get the mix right. I don't know if the manufacturer ever reads these reviews, but I am an industrial designer and I have designed a different container that I think could work with much better results....but don't change the recipe for the epoxy...5 star stuff. | I used this to cast flower coasters and fill crack and knots in wood, works great but it stripped alot of the piment out of the flowers i cast, blue became a sickly green and the artifical pigment powder i was using went from and orange to a yellow so becare if you are tring to get a color out of it. | eng_Latn | 21,915 |

Can spray paint or a marker block UV for solder mask/resist? I am planning to make a PCB and putting solder mask on it but I don't have my own laser printer to print the transparency for the mask. I do, however, live near a printing shop with a laser printer who can print glossy/photo paper but not transparencies. So I am thinking if I can use spray paint or a marker to "draw" on empty transparencies by using a soldering paste stencil as a guide. I have seen question being answered but its not what I'm looking for. So will spray paint or a marker block UV for solder mask/resist so that the pads won't dry? | Use spray paint to make mask for pre-sensitised board? I'm about to etch my first simple board for a project. I have a pre-sensitised board that (as I understand the process) you expose to UV light, then develop the board in a sodium hydroxide solution, then etch. The UV light will negatively affect the protective lacquer and developing it after exposing washes away the lacquer, making the board ready to etch. I got the lye and I got sodium persulfate for the etching but I did not have any transparent paper as I thought I did! And it's impossible for me to get a hold of it in time (= this weekend, I live far from the city and it's a small one and I haven't found any place that stocks it so I have to order online and that's sometime next week I'd get it at the fastest). So I am looking for an alternative solution. What I am considering is printing the design to regular paper, cut out a mask carefully from this paper and place it over the board and paint a mask on. Spray paint most likely, then in theory I would have a UV mask. Anyone see any flaws in this plan? | Atmospheric pressure experiment using a cup with a fluid to hold a glass plate When I was in high school, my teacher did an experiment to show the power of atmospheric pressure. Experiment: Prepare a glass bottle, fill with water, put a glass plate on the bottle, make sure there is no air in the bottle, just water. Hold the glass bottle and plate, and invert them. Slowly, release the hand which hold the plate. Because the atmospheric pressure, the glass plate will not fall down. Question 1: As we know, if we didn't put water into the glass bottle, just air in the glass bottle the glass plate will fall down. So, If we use other liquid instead of water, this liquid has smaller density than water, like alcohol, the plate will not fall down. But, if we continue to chose the smaller density liquid until the liquid has density like air the plate will fall down. So, if there is a threshold density of liquid make the plate between falling down and not falling down? Question 2: If we put the bottle and plate into water slowly, when the plate and part of bottle are in the water but part of the bottle still above the water, will the plate fall down? Question 3: Continuing question 2, when both bottle and plate are in the water I know the plate will fall down. So, how does the pressure of water and atmosphere change? Is there a good description of this phenomena? Why does the trick continue to work with lower density fluids and why does placing the plate in the water cause it to fall? | eng_Latn | 21,921 |

This is the very scientific principal that explains how water goes from the soil upwards into the stem of plants. Plants contain many vein like tubes that carry water from the plant's roots upwards to the plant's highest leafs via capillary action. Try this experiment to see capillary action in action.\n\nWrap the plastic wrap around the knitting needle and then tape the edges so that you have formed a tube. Remember, the narrower the tube, the more pronounced the capillary effect will be. \nOnce you have taped the plastic wrap, pull out the knitting needle. Make sure that the new plastic tube is not bent and is open at both ends. \nNow pour a little of the food coloring into a glass half filled with water. \nNow place your plastic tube into the glass of water. \nExamine the tube carefully. The dye should climb up the tube above the level of the liquid in the glass. \nNow try the same experiment with varying levels of water in the glass. Does this make a difference? | eng_Latn | 21,935 |
