Calling British Amateur Scientists!

From the BBC: Snail "GPS", Facebook psychology and crowd dynamics at music gigs: these were just some of the ideas submitted during last year's search for "citizen science" projects. Now, Radio 4 is launching its search for the next BBC Amateur Scientist of the year. A panel of judges, chaired by Nobel Prize-winning geneticist Sir Paul Nurse, will select four finalists. The shortlisted entrants will then have their ideas turned into real experiments, with the help of a professional scientist. Last year, 70-year-old gardener Ruth Brooks won the award for her research into the homing distance of garden snails. She found that Helix aspersa, the common garden snail, can find its way home from up to 30m away. But for gardeners to be sure that their snails will not come back, they should be moved over 100m. Do you have a cool idea that could be turned into a proper piece of scientific research? The judges for So You Want to Be a Scientist? will be talking about what they'll be looking for in this year experiments on Material World, Thursday 29th September at 4.30pm, Radio 4. Entry is open to anyone over 16, who is a resident in the UK and applications can be submitted online until 31 October.

does this works in practical?

Car running without fuel first i will take some water in petrol tank of a car.now i will connect it to a electrolysis box. the electrolysis gets electricity from battery. now 2H2O[water] on electrolysis divides into 2H2 + O2 this in the engine with the help of glow plug combines and gives 2100C -2800C temperature  and water [in gaseous state] with that temp[ car works as in normal case].The water in the exhaust cools down and again goes back to the water tank. By this the cycle continues and car keeps on working. it will be like this, Battery                       Electrolysis box  [water to it comes from water tank ]              2H2,O2                 2H2+02 [in engine]                                                                                                                       2H2O + 2100-2800 Celsius temperature [engine works] water tank please tell me does it really works out or not

How can i compress a biogas from a compost tank without risk of ignition.

I already have minor semblance of a design but, i always prefer to consult the hivemind before doing something potentially stupid(i'm missing enough fingers). so, big picture is to create basically a sealed septic tank tied into the water lines of a residential house, which would produce methane to be stored year round then used during the cold season. not so much that i could cut off the natural gas line, but enough to reduce the bill.the design so far is a gas line coming from the septic tank connected to a bladder sitting inside a large tube. once the bladder reaches a nominal capacity, it will trip a sensor near the top of the tube activating a compressor until the bladder retracts to a lower set optical sensor turning off the compressor. somewhere in this mix i have the intent to set up a large air filter filled with that "oxygen eater" stuff they use in food storage applications. as well as several o2 sensors in the main line set up to stop the compressor and activate a solenoid valve to make sure no oxygen ever get to the compressor. what i dont know, is what kind of compressor i should be using to avoid any type of possible spark. proper placement of the o2 sensors, and if a giant air filter for eating oxygen already exists or is that something im going to have to make the hard way.

Tomorrow

Tomorrow is the Science Fair at my school and I'm not finished yet. My aim is, Will Climate Change Affect The Growth Of Grass In The Next Ten Years? I've done the testing and I'm writing the conclusion. I need to know some plants that are sensitive to temperature changes. I have already searched and can't find any (I must have very bad searching skills). I also need to know what kind of chemicals that plants use. I'm kind of panicking right now!

Does yoga do what it claims it can?

Hi people!  Does yoga really do what it claims to?  Here in my place, my parents and elders claim that yoga can prevent diseases(like cancer, or blood pressure variations, diabetes etc), and even help in curing of above mentioned diseases. Is it really true? If yes, what is the mechanism behind it? If no, then what does it really do?

Is homeopathy a proven science?

Hi again people! This is yet another question to which i have to get definitive answers.  Is Homeopathy a proven science? Alternate medicines like homeopathy, Ayurveda are so common in my country, that most people tend to believe them blindly and are ready to take "medicines" from them for all kinds of problems, from Not-really-worth-bothering stuff like common cold, to moderate stuff like diabetes, and even extreme life threatening cases like cancer. To be honest, even i didn't bother looking into them much and few years back, i thought MAYBE it does work, after all so many people take it. But in my recent years, i have developed a condition known as psoriasis, so i had to start bothering as most people force me to take these medicines, as thus far, "Allopathy" does not have treatment to this condition. But alternative medicines claim they do. i was getting a little skeptical. When i started really questioning stuff, i didn't get quite satisfactory answers. Doing a little research on my own, i have seen videos from one of my favourite intellect, Prof.Richard Dawkins. He says that homeopathy is mostly bogus. When i question this to the people around me, specially the elders, they just throw it out of the window, and tell me that i am too young to understand stuff, and people who claim things know nothing about these kind of stuff. It is the same in case of Ayurveda. How far are these claims true? Is homeopathy(Alternative medicine in general) a bogus? If that is the case, then why is it so famous? Why is the community adopting it despite all this? Or have i misunderstood the concept? Do pardon me if my question was too long :)

My Theory for How Gravity Works

So I've never really found out how gravity actually works, why it happens. But a few days ago I had a epiphany. I don't know if I spelled that right. So everything is at least a little bit magnetic, even stuff like wood, no matter how little. So all of this stuff would be attracted to all the other stuff electromagnetically, right? Even a little bit? So when you get huge amounts of this stuff (I'm thinking planets here) there is enough electromagnetic attraction to pull it together, and voila! We have gravity! Plus when you have planets, there's tons of stuff like iron and other metals and metaloids, that could be very strong, magnetically. So if I'm wrong (which I probably am), can someone explain how gravity actually works to me? I'm constantly thinking about stuff like this, I get theories like this every once in a while, many of them right. But not this complicated, more stuff like figuring out how air pressure and vacuums work, but basic principle stuff.
