Science Section

Is it just me, or is the science section as a whole getting suckier?Science is my best subject. I get A's in school, avidly read Scientific American and other science magazines, read physics and astronomy books, and once gave a 45 minute speech about the viability of Algae as bio fuel (Instructable coming soon) for a science project. So obviously, when I first joined, I ate up the science section, reading through great instructables, like the ones created by egbertfitzwilly (oh, shut up, you know who I mean) and other great instructablers. I loved them. Now however, it seems to be full of toy guns, electronics projects that belong in tech and recipes. Goda**it, just because your beer recipe uses yeast doesn't make it a freaking science fair project! If your instructable doesn't need a second category, DON'T GIVE IT A SECOND CATEGORY. Whoa, that was hard, eh? For instance, this. Its not a bad Instructable, sure, what what the heck is it doing in the science section? How about the ginger beer instructable? Or smart LED's? Or a coding machine? I want, and I'm sure others want, more Egbert and Nurdrage styled instructables, with cool stuff that makes us go "Whoa" and want to do it ourselves, not some of the random junk that people seem to throw in to get an extra 3 hits.

What's your Science Fair project?

So, this is how our science fair project for the elementary school science fair turned out. Everyone should be encouraged at a young age to have an interest in science. As they say, "If you ain't having fun in science(or any other subject), you ain't!" This was crafted from paper mache(monocoque nose shell over a cardboard superstructure), laminated cardboard eyeglass frame, and homemade science fair display board.We thought about everyone wanting to touch the display so we put black yarn in the open nostrils below to simulate nose hair if someone decided to pick this nose. We couldn't add slime. Gross-out factor is high in the fun quotient. Remember, you can pick your friends; you can pick your nose; but you can't pick your friend's nose... It would be great if we could see what everyone else worked on. Of course we need ideas to top this one for next year's project! Edit 5/20/08Yay! Caitlin was co-winner for first place in the Fourth Grade Science Fair at school. The other girl won for testing to see if different strengths of Listerine actually helped kill germs in the mouth by doing swabs and cultures. Congrats to the young ones.

Carl Zimmer's Science Tattoo Emporium

Underneath their sober lab coats and flannel shirts, scientists hide images of their scientific passions.Writer Carl Zimmer wondered aloud whether many scientists have tattoos that reflect their science or other geeky interests, and the response was an emphatic yes. He's posting the photos and stories of scientific ink up at the Science Tattoo Emporium. Today's is a gorgeous backpiece of the tree of life, belonging to a grad student in zoology at the University of Melbourne.Of course, now I'm curious -- do any of you makers, builders, tinkerers, and crafters have geeky tattoos? If not, what would your tattoo be? Carl Zimmer writes a fascinating science blog called The Loom along with other science journalism.

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.

The science behind this self watering system for plants

Hi, I was watching a video for a self watering system for plants (link below), and was wondering what the science behind it is called. I also had a problem where no water came out of the bottle because the hole I made at the bottom was too small. As soon as I unscrewed the cap a little, the water came gushing out. https://www.youtube.com/watch?v=Ffe7JfYyBFE Thanks :)

Brooklyn Science Fair: Clean Energy (Submissions)

Bushwick Project for the Arts in Brooklyn is a ~3500 sq. ft. art space off the Montose L stop in Bushwick, and we are putting together a "science fair" for adults. Basically we want to get some people to use our space to demonstrate ways that city folk can help the environment on a day to day basis. All of us here at the space have been really saddened by what's happened in the gulf and wanted to have a positive event to focus on clean and renewable energy. We're looking for folks to submit ideas for installations, demonstrations, films, presentations, or whatever you've got or do. The event is going to be on Saturday, June 26th and will most likely start early evening. Send me an email if you're interested... wesmarcarelli@gmail.com

Computer Science Project: Automated Follow Spot

Hi all!  This is my first post on instructables. I've been using this website for years to facilitate many projects, however this is the first time I'll actually be posting any questions of my own on the forums! Exciting! I'll cut to the chase, for my computer science A - Level I am required to complete a programming project, complex enough to get me a good grade, but feasible enough to actually complete! I decided to take a more practical approach and have arrived at the decision to make a robot of some kind. As I'm heavily involved with the drama department in the school I wanted to create something that could also help them. I decided upon an automated device that can use some form of trilateration to determine the position of a person on stage and then position a light to light them up. For those who have more experience in the world of technical theatre, I'm talking about an Automated follow spot. For those who don't here is a link to a wiki page.    The premise being that a person normally has to control a follow spot, pointing it at the person (or people) on stage, to light them up. An issue we have is that sometimes we don't have enough stage hands to operate the follow spots, which means they're left by the wayside. My idea will negate the need to have a human operator and should simply follow the person around the stage. The main idea at the moment is to use a single long range bluetooth transmitter, attached to a wristband (which would be worn by the actor/actress) and have three long range receivers, which in conjunction can trilaterate the position of the actor/actress and position the light to illuminate them. I have a couple of  questions: 1. Firstly, is this feasible? This is a project that I really want to see through to fruition, especially as it will count towards my final A-level. For someone of my level of knowledge/experience - is this possible? 2. What would be the best method for transmitting the radio signal? Bluetooth sprung to mind instantly, but is this the best option? I know there might be potential pitfalls in that a theatre is full of metal items and interfering signals that could disrupt this, so are there any better alternatives? I know there are only two questions for now, but I've only just started the design of the project. I'm sure when I get seriously into it I'll have many many more, but I trust that the good people of instructables will be able to provide some help! Thanks again, Eliot C-Hill
