Until I get unbanned on my main. Ask me science things. Response times may be poor if I decide to respond with a huge multi-paragraph reply.

"What is the coolest fact you know"
The coolest? Oh damn, that's a hard one. With a field as vast and fascinating as science, it's really hard to pinpoint one specific coolest fact. I guess the fact that 65 BILLION neutrinos will pass through just your fingernail in one second. Or the fact that we, in some sense, are descendants of the stars themselves.

Yeah, the star dust thing is really cool and neutrinos? what are those?

"and neutrinos? what are those?"
They're a kind of lepton, which is a subatomic particle. They have a mass BARELY greater than zero. They're very similar to electrons, but they don't have any electric charge (hence the name "neutrino").

"What's AgNO3?"
You literally chose the most household-named compound on planet Earth, man. Silver nitrate is probably one of the most well-known silver compounds there is.
"Why do human hermaphrodites, like myself, exist?"
It's hard to explain this in a way that wouldn't get me filtered or banned, but let's just put it this way. It happens when someone is born with tissues from BOTH reproductive organs. Sometimes it just manifests as a slightly deformed organ, and in rare cases, they will have both. It has some chromosomal correlation to. Some hermaphrodites will have XXY on their 23rd chromosome, for example. This is known as Klinefelter's syndrome, but it isn't too dissimilar from a hermaphrodite.

Got mass-reported by a very specific person. Won't say any more because I don't want this alt to get banned too, but yeah. Mass-reported.

Still working on the Big Bang question. I'll get to the other questions shortly. I'm getting a bit carried away and typing a mini-essay. Whoops.

"What proof do we have of the big bang?"
I'm going to try to condense this as much as possible. There are three main pieces of evidence in support of the Big Bang Theory. First is the red-shift of other galaxies, then the mixture of certain elements, and finally, CMB radiation. Red-shift is possibly the most well-known piece of evidence. Red-shift is the result of something known as the Doppler effect. As objects pull away, the wavelength of the light they give off is stretched. Longer wavelengths tend to create warmer colors; in this case, it's red. Using the knowledge of the Doppler effect, we can tell by the red color of other galaxies that they are receding away from us. This suggests a uniform outward expansion, which could potentially be traced back to a single point. If everything is accelerating away from each other, that implies they originated from a specific location. Next is element mixture. I won't go into too much detail because I've got a huge back-log of questions, but I'll explain it as best as I possibly can in a short amount of time. When the universe cooled after the initial expansion, it created many of the elements we see today. Hydrogen, helium, oxygen, carbon, etc. etc. etc. The Big Bang Theory predicts how much of those elements should be present during the early periods of the universe. If we look at the composition of distant galaxies and stars (which are very old, considering the light takes time to reach us), we can see that these predictions actually proved to be correct. This can't be observed in younger stars because the elements they contain came from their parent stars too. They will contain VASTLY different elements than the oldest stars, which came into existence many years ago. Finally, we have CMB radiation. This is most definitely one of the most compelling pieces of evidence in support of the Big Bang. Obviously, the universe was VERY hot in the moments following the Big Bang. I'm talking incalculably hot. It's hard to even comprehend how hot it was. This heat also produced a glow. Before we confirmed this, the Big Bang Theory predicted this glow had existed; not only that, but it also predicted that it would be detectable as microwaves on the electromagnetic spectrum. Both predictions turned out to be entirely correct. Using highly accurate instruments which measure the background microwave radiation of our universe, we have come up with a very cool-looking map of this microwave radiation. It has come to be known as the CMB, or the Cosmic Microwave Background.

"if i put gunpowder in oil and ignited it what would happen"
What kind of oil are we talkin' here?
"why does molten salt explode if it comes into contact with water"
Let's just clarify something real quick. It can't just be any kind of salt; it HAS to be sodium chloride. That's very very important. Let's rule some things out. Temperature alone is not a factor; for example, hot metal will not cause the same reaction upon making contact with water. It isn't the sodium either. Molten sodium will react with water (it causes a cool flash), but won't explode. It's not anything to do with a chemical reaction either. The pH remains the same after the reaction occurs. While temperature isn't the only factor, it is a major one. When something that hot makes contact with water that quickly, the water almost instantly vaporizes. Steam takes up more volume than water, which causes a rapid expansion. This causes what seems like an explosion, but it couldn't really be considered one. Because NaCl violently throws particles around, it reduces the Leidenfrost effect (which typically occurs with hot metals when they make contact with water, reducing heat transfer), causing an even more violent expansion. That's just what I can make out from it. I'm not entirely sure, but from all of the experiments I've seen, this seems to be the most likely.
"why does cornmeal kill ants"
They can't digest it, which can actually cause them to starve. It's very similar to the way chocolate and grapes kill dogs. They process it much more slowly, which can allow toxicity to build up in their system.
"Why do narwhals have horns?"
They're not really horns, they're tusks. We don't fully understand its purpose, but we think it sort of acts like a weather sensor, and can even tell the salt content of the water.
"What do I need to make a formula that gives people instant rashes"
Rashes are usually the result of histamine. If you can trigger an allergic reaction in the target's body, you're all set.
"holy mothercucker i just choked on my drink reading this"
Yeah, it's pretty insane.

Why or how? Both have always been hard to answer, but one is almost impossible to answer from a purely scientific standpoint.
