- There is a scene in the movie Skyfall where the villain removes his upper jaw, exposing his scarred and almost destroyed face, and claims it was due to a Hydrogen Cyanide capsule. Could Hydrogen Cyanide actually do that kind of damage? Would the villain have even survived in reality?
- How do annual vaccines remain in the bloodstream for a year instead of wearing off a few days later? Additionally, why are some shots (I.E. Tetanus) recommended every X years instead of annually?
- How can i control the wavelength of light when i pass it through an object using refraction?
- If infrared light is hot, then why doesn't visible light cook us? Visible light has more energy than infrared, right?
- Is there a byproduct of the production of alcohol that is destroyed in the process of distillation?
- Why don't animals like Seals suffer from decompression sickness?
- Why is music around the world based on octaves? Do they share common roots like the Indo-European languages? Is there music in other parts of the world that's not based on eight notes and their harmonics?
- Why can alpha and beta radiation not penetrate particularly thick materials?
- Is it true that vehicles (cars, semi-trucks, boats) have a tighter right-hand turning radius than a left-hand turning radius? Why is this?
- A glass breaks when it experiences a big enough temperature difference. But will repeated, smaller temperature differences over time eventually cause the glass to break?
- What's the natural form of Asbestos and how is it found in the mineral bed?
| What’s stopping the water in lakes from seeping into the soil and ‘disappearing’? Posted: 15 Dec 2018 04:57 PM PST Thought about this question when I was watering some plants and the water got absorbed by the soil. What's keeping a body of water (e.g. in a lake) from being absorbed by the soil completely? [link] [comments]  |

| How can i control the wavelength of light when i pass it through an object using refraction? Posted: 15 Dec 2018 08:26 PM PST Hey redditors! I am currently working on a design on a product that involves the refraction of UV light through a certain object (prism or something, haven't decided yet) in order to refract the light. However, it is extremely important for the light to be a specific wavelength once it is refracted and any changes in the wavelength could ruin the whole product design. I was wondering what factors we would have to account for to make sure the wavelength of the light remain constant when passed through the object and what sort of object I would have to use in order to refract the light without changing its wavelength?

| Is there a byproduct of the production of alcohol that is destroyed in the process of distillation? Posted: 15 Dec 2018 04:56 AM PST If I drink a beer, a wine, or a cider, it will trigger a migraine. However, the trigger is not alcohol itself. I can drink whiskey, vodka, rum, or whatever until it gives me a headache from the hangover like any other human being. But if so much of a sip of a fermented alcohol passes my lips, I'm shortly hiding in my darkened room under all the covers. If I'm able to identify a trigger down to the chemical compound, it might enable me to better avoid migraine triggers so I'm very grateful for any input! 😊 I'm really hoping this doesn't violate the rules since the motivation to ask this is based in my personal healthcare.

| Posted: 15 Dec 2018 05:12 AM PST I remember watching a video (like a couple years back) about remote controlled cars and how some cars will take longer to make the same left turn as they did with a right turn. The guy in the video drove the car in a circle with it doing the tightest possible circle it could on each side, and the left-hand turn made a much bigger circle than the one that came about from the right-hand turn.

| Posted: 15 Dec 2018 12:12 AM PST I apologise in advance if this has been asked, but for the life of me, I couldn't find a clear answer. I regularly pour hot water into the same glass and have never had any problems. Until yesterday, when the glass cracked. Now, I realise it could have been a particularly cold day, or hotter water than usual, which caused a greater-than-usual temperature difference, which is why it broke on that day, but none of the other hundreds of times I've poured hot water into it. But I did wonder, could the repeated stress over time, (caused by me filling the glass with hot water every day) have caused it to "fatigue" in some way? Or create tiny cracks or weak points? Such that, the last pour - rather than causing a greater-than-usual temperature difference - was really the "straw that broke the camels back"? And, acting on years of "fatigue" or "stress build-up" cracked an already vulnerable glass? OR, does glass not work that way? Thanks for any answers! I know it seems like a fairly obvious question, but I just couldn't find an exact answer. [link] [comments]  |
| What's the natural form of Asbestos and how is it found in the mineral bed? Posted: 15 Dec 2018 12:09 AM PST On the news about the J&J Asbestos issue they claimed that Asbestos and Talc are often found together in similar mined veins and this would cause the cross-contamination...This is the first I'd heard of asbestos being a (mineral?) at all and I'd like to know a bit more about how it occurs in nature.
