Killing ants with Popcorn

http://www.youtube.com/watch?v=CL78eVVW9_M&t=65 Basically this guy says that you can kill ants by shredding popcorn Kernels. Is this true? I want to know before I shit-up my house with an even worse infestation than I already have.

What are some good sources towards sound theory? I've been interested for years and it may look like I'm moving into audio production/engineering. I just want to have something to read up on if I ever feel like I'm up against a wall and more specifically, is there anything related to recording from a low fidelity source to high fidelity media? I already have a basic idea on how to tackle this (assuming I get this assignment), but it would be nice to have some documentation to look over to see if there's anything else that could aid. Also sound thread I guess

/sci/, I'm having a dilemma. I'm going into my senior year in high school, and I got accepted into a very prestigious research program/class. In case you're wondering how prestigious, two girls and the teacher who leads the class went to the White House science fair earlier this year with a water purification device powered by a bicycle (you may or may not recall President Obama riding on said bicycle.) I have an idea for a research project, but I don't know if it's good enough. My idea is to investigate whether or not the sound barriers for the local interstate affect the spread of photochemical smog. I would go about doing this by acquiring an infrared camera that can show ozone in photos. In addition, I would investigate the incidence of respiratory infections in local neighbor hoods, and use records of wind patterns to see how the smog may be affected in regards to it's spread. So, /sci/, is my idea sound, or should I do something else? This can be an environmental science thread in general.

Idea for an experiment

6 more posts in this thread. [Missing image file: a04923101a683ce80e37cb4f27b043c9ff674e4e.jpg]
Hey /sci/. I recently came up with an idea for an experiment to either prove or disprove the existence of an afterlife. Basically my experiment consists of putting a death row inmate in an MRI machine and then having them undergo clinical death by lethal injection and then administering an antidote before they undergo information-theoretic death. On the wall nearby I will have an analog clock that is covered by a shroud that I will uncover when the MRI scans indicate all neural activity in the cerebral cortex has ceased so when the subject is revived and reports having an NDE he can tell us whether or not the clock was uncovered and what the time was so we can tell if the occurrence of the NDE coincided with the moment all neural activity had ceased in the cerebral cortex. If he says the clock was covered then it proves that an NDE is just a dying brain's dream. If he says it was uncovered and gives a time that is after the moment neural activity ceased in his cerebral cortex then it proves that NDEs are real experiences and that the mind can exist independently of the brain. My question to you /sci/ is whether or not this experiment is sound or if there are certain factors I failed to take into account that I would need to eliminate or monitor that might affect the results? Also I would like to clarify that this is not a religion vs science thread. I am simply asking /sci/'s expert opinion on how well my proposed experiment adheres to the scientific method. All our scientific facts are based on empirical observations. If there was empirical evidence that magic is real then we would have no choice but to accept that but the evidence says magic isn't real so that's that. Pic unrelated.

If two spaceships are moving in opposite directions at the speed of light relative to a stationary observer in the middle, does that necessarily mean that their speed relative to each other is double the speed of light?

Sleep, I'm sleepy. And that's exactly what I'm going to talk about. Is it possible that humans don't require sleep, why do we sleep in the first place, is it to "recover" energy, can't we just inject "energy" into our body?? Is it because the brain needs to do a REM? Can't we like save the state of the brain before it's sleepy then restore it? I've tried the thing about the uberman sleep, it's bullshit, sleepig more times on a day won't make me sleep less overall, well if it does, it has issues. So why exactly am I wasting 8 hours of my life everyday in 2013 How impossible is for a body to simply not sleep? (Without any issues?)

RF thread

His name was Jason. A veteran of the trade show circuit. He was only in town for one day. Had a big package to deliver. It was a modified antenna. High performance. Had been kept under wraps. But it had come time for some real world exposure. He had the unit in a canvas container. You could see the outline of it through the material. She was watching him get his booth set up at Wispalloza in Vegas. She loved going to Vegas, always eager to have some fun. “If you won’t show me your antenna and let me play with it a bit can you at least tell me what kind of pattern it has. “ she sighed while subconsciously fingering her ODU connector. He looked into her eyes. She wasn’t the typical booth babe, she was serious about picking up some strong signal. “Not narrow, but still enough gain for good penetration.” He said. He noticed her eyes growing wide. “Especially in deep bush - I trimmed the sidelobes. Smooth and clean pattern” he said with a smile. “Mmmm” she said, as if just tasted some delicious cheesecake. He looked down - pushed some tools around with the toe of his cowboy boot. “Look” he said: “I don’t have a radome, and without a radome there is the risk of spurious emissions. But in your case, if you really want to give it a try, I am ready to hook up.” “Oh wow” - “But we don’t have a license. We might get caught” she said - a bit on the breathless side. “OK, tell you what” he said “If I don’t fully modulate, I probably won’t launch dangerous emissions. You can trust me”

You have 10 seconds to explain why this won't solve the world's energy problems.

This may be a dumb question, but are there any theoretical weather phenomena? That is, have models/simulations predicted weather that hasn't been observed? (I'm not talking about long-term climate stuff, but short-term things like rain or tornadoes).

Let's have a scientific study of UFO thread. What if they are real? Most of the videos online will be fake or misinterpreted. Some of them may be authentic. Youtube links are very welcome. This is a compilation of the most recent UFOs around the world (July 2013) https://www.youtube.com/watch?v=tzwiWe3m5uM

Hey /sci/... When I was younger, my mom used to do reflexology. I think it's regarded as bunk or not scientifically proven? And I'm not here to claim it works, if I remember correctly it never made any difference... But every time she used to do it, she used to press the ends of my toes and things would POP really badly, it felt like bubble wrap bursting in my toes. I used to hate it because to be honest it felt very uncomfortable and weird... What was this feeling caused by? I Googled literally just now and it seems others likened it to bubble wrap bursting too... But nobody scientifically explains what it is? I've NEVER been able to replicate the feeling myself by poking the ends of my toes. Please help me /sci/ (I can't ask my mom she passed away)

So I come from a poor family, and recently I found out that appearently (please confirm) most people flush the toilet every fucking time they take a piss/dump. Isn't that an incredible waste of drinking water?! I usually flush only ever third or fourth time and it has the same effect. So why? It can't be just because of the smell - it's not like you're in the bathroom most of the time when you're at home.

question: if economics is a 'science', then why aren't there any Laws and why do so many economists have extremely different views?
