    Hi Mental Floss! I've been a huge fan for a really long time and LOVE the videos! I have had a slight concern for a while though about the volume levels of your introduction music. The traditional music used always seems to be significantly louder than the introduction narrator and video with the exception being your holiday music and Big Questions intros. I know it seems minor, but it has startled me and many others I know when watching the beginning as viewers frantically attempt to turn down or mute the opening sequence. I still love the content and am still a huge fan, but I would love to be able to binge the videos without adjusting the volume for each video :) Thanks Mental Floss and DFTBA!!!

    Could you please attempt to proffer a proper designation, or classification, that best describes the process through which a complete human body might undergo hyper-rapid degradation/decomposition/degeneration, possibly on a molecular level- though any state of "breaking down", or "falling apart" will do-, while the host is still alive? After suffering a dream in which I was privy to such an experience, I've tried, to no avail, to find any situation where this particular state might exist, and have a name for it. Please?

    I would like to see your video about how humans are actually not alive.

A pile of rocks is a collection of molecules and atoms but we don't consider a mountain a living thing; and so on... thanks for reading.

    Burning question! Or rather, series or related burning questions! Why do we sell honey in bears? I mean, I know that bears are opportunistic omnivores who have been known to enjoy honey and bee larvae and things like that, but did that knowledge precede modern honey packaging? Is Winnie the Pooh involved? (there's a question I never though I'd ask in earnest...) Did one brand start doing it and their success caused everyone to follow suit? I know this isn't a worldwide practice either, but in America, it's actually difficult sometimes to find honey NOT in a bear. I MUST KNOW WHY/HOW THIS CAME TO BE.

      +Reuben Oakley Why does it happen even when I have a heater in the bathroom? Really, I already know the answer, and that is only part of it. Another explanation is that water comes out of a shower head with a lateral rotation parallel to the ground and that also creates another type of gust It just bugs me that they repeatedly said it would be next video and there is no explanation for why they uploaded other big questions instead the last two weeks.

    • Reuben Oakley
      Reuben Oakley 3 years ago

      The hot water causes the air in the shower to heat up. Hot air rises and thus attempts to escape from the top of the shower (usually through the gap between the curtain rod and the wall). This creates an imbalance of air pressure and air from outside the shower comes to replace the air that left. In essence, you made your own wind!

    Big Question: Why do we look terrible in other peoples photos?

    • Reuben Oakley
      Reuben Oakley 3 years ago

      Cheap cameras, bad photography skills, social awkwardness or a combination thereof. If you want to look good in a picture, follow the rule of thirds. Keep faces or eyes around the imaginary line 2/3 the way up in the photo (faces for full or half-body pictures and eyes for pictures of faces). If you want more details on this, Google the rule of thirds, adding the word "photography" to the search may give more accurate results.

      +ZeroTooL88 Alright, I seem to have been corrected, thank you. Although Wikipedia isn't exactly the most reliable source on the internet... The only reason that I said anything after your comment was because I was taught that the color was first and the fruit named after it. Even in the article you mentioned, the only evidences used are the earliest known mentionings of each use of the word, which could change with new evidence. For now though, this goes to you.

    • Reuben Oakley
      Reuben Oakley 3 years ago

      It doesn't. Evolution cannot plan ahead because it is a random process. I know that they said this is not true in their Big History video series, but they are kind of wrong. I understand and agree that natural selection is not random and will only help good traits. However, the mutation process (which is what creates new traits) is completely random. A simple analogy is that mutations are the gas and natural selection is the engine, each one needs the other to be useful. However, there is no driver saying which way to go. Also, the mutation process is the least efficient fuel EVER. When we use gas in a car, we usually get around 10% energy efficiency. That means that we properly use around 1 out of every 10 parts of gas. Mutations, however, take MILLIONS of occurrences to get something useful. In fact, when researching the experiment behind the article "Evolution In Action: A 50,000 Generation Solute to Charles Darwin", I found that the actual rate of useful mutations (and thus, evolution) is too slow to satisfy the timeline used in evolutionary theory. It was some interesting stuff! DFTBA

    • a1rondog1a
      a1rondog1a 3 years ago

      I found it does matter how much you put in at one time. And doubling the time for two items just doesn't work. How big and how much you fill a container you're using to heat food matters as well. For instance, a bowl filled to the top with stew will take longer than the same contents in a larger container. Most of this I found out thru trial and error methods but it's not like it's dangerous or anything. More of a "Time" hack than anything. Use your power levels too, to time your meals as well and do other things at the same time.

    Why does the boiling temperature of water change with altitude?

    • Reuben Oakley
      Reuben Oakley 3 years ago

      Higher altitude means less air on top of you and thus less air pressure. Less air pressure means that the water is not being held together as much and will boil at a lower temperature. It is the reverse with lower altitudes.
