Works via a cup with holes drilled on the bottom and a piece of tape acting as a simple valve on the top. If the tape is peeled back water/air can flow, otherwise if kept level the water will happily sit there. Partially based on thread here a few weeks ago, wanted to prove to myself that this concept would work in reality(beyond a simple straw or pipette). Have some thoughts that it might work for novelty applications(fish tanks, water spheres). A somewhat practical, bottom filling bucket could also be done, but haven't figured out a good valve design to minimize manual operation. Goes without saying applications would need to work around the obvious issue, but…

Many people know that any kind of trashes are useless. But I keep wondering are trashes really useless? I mean are their substance really can't reused or maybe recycled to make something new like energy or from chemistry perspective, can't we make useful substances from trashes'. I know some countries already imported trashes around the world and turned into something useful such as energy. What keeps me wondering is in the scale of home-industry, can't we use some of substances from some trashes (mixed trashes) and make something new? or maybe from certain trashes, like just papers or just tissues, or just organic, or just plastic trashes. I don't mean to recycle it…

If you decide to try this Experiment please post your result. Fact: like magnetic poles in a magnet repel each other. Question: Shouldn’t two transmitters operating at the same frequency and phase also repel each other. Supply: A: 2 Transmitters operating at same frequency and phase, they should be directional most likely low frequency may be best. B: Water environment: pool, bath tub, big bucket with water. C: Toy boat Experiment Idea: 1: Obtain two transmitters that will operate at the same frequency and phase. 2: use a body of water for experiment (pool, tub.. ect.) 3: power up one transmitter o…

Hi,my teacher give us an assignment to build a hydraulic jack but using any chemical reaction to push the piston and need to be able to hold weight of 500g.(p/s:using recycled item).I tried it with a tube coming out of water bottle and connected to a 2 syringe which is the base to put the weight.In the water bottle,I use vinegar and baking soda to produce CO2 and push the piston.Unfortunately,it was only strong enough to push one syringe without the weight.Any idea/suggestion to make it better?

The theory of motion of a flying saucer. https://www.scienceforums.net/topic/117177-flying-saucer-picture-project-of-a-spacecraft/ This theory explains the appearance of an impulse driving a flying saucer.

(Version 2) (Version 1: Monkey Man, and Golden Ratio) (My A.I. project theory is named "Eugene" short for "Eugenics" .................. You will learn how to Build a "Cognitive Engine", form this, you will learn how to "Create Intelligence", you will learn how to apply "Build Learning", these are qualifiers for "Artificial Intelligence", in the fundamental sense this means "HAL-9000", yet like the Movie, I'll come back to this statement (Everything I say will be very simple, if it isn't, talk to me about it, so I can amend a brief statment) : Cognitive Engine Principal = HAL - 9000 = Hyper Binary System Each Dollar Bill represents ab…

Bacterial Cellulose / Vegan Leather / Scoby Project Attempt to form bacterial cellulose using Kombucha recipe as a starting point. The result is also known as a SCOBY, a Symbiotic Colony of Bacteria and Yeast. This was first really popularized(online anyways) by Designer Suzzane Lee with a set of Vegan "Leather" clothes. Thought Emporium / Scihouse improved on this a relatively simple water proofing strategy, involving a Cup Coconut Oil and 1 spoon Beeswax-Mineral Oil mixture. Researchers are looking into this as well. Has a number of useful properties. Expensive to produce on an industrial scale, but can make use of waste products. Test 1 ⦁ 1 Ga…

Hello All. I'm looking for info on building a CVD chamber. I am aware that there are several methodologies for this process. I am looking for the instructions a 7th grader would use for the science fair, I'm not a 7th grader, I'm a science buff who never really had much of a childhood. I'm also not a chemist, but I am a machinist. So I probably need instructions for an individual slightly more knowledgeable than a doofus. I'm specifically interested in Sic or diamond . Any suggestions on a book or other resource would be appreciated. Making rocks out of gasses sounds like a cool project! Thanks.

Hi...my idear is to drive two separate air tube coils at the same time... one around the other... but held apart so when they are given a charge each coils electromagnetic field works in unison with the other. Each coils input voltage is directed so the outer coil is fired in reverse and the inner coil fired so the cores em-field is forwardly moving the coils also would have a soft iron tube enclosing the magnetic field forming an em-shield. A bullet of aluminium with a drill hole at its rear is spun by an electric motor to a high speed just inside the beginning of the barrel, the other end of the tube has a tea intersecting tube and the end of the barrel…

Hey I'm making vacuum cannon. (If you don't know... Buy PVC pipe, put a pinpong ball to it, close both sides of it with stretch film. Create vacuum. Prick one stretches. And ball goes out!) I am using vacuum cleaner for vacuum. But I have a problem. When I prick stretch ball goes to hole which air goes(vacuuming hole) to. I tried close cleaner before pricking stretch. But air came back to the pipe from vacuuming hole. So, I think something to put between cleaner and pipe. It shouldn't let air come back to the pipe, only pipe to cleaner; no cleaner to pipe. If I have it, I will create vacuum, then I close cleaner, air will not come back. I will shoot cannon. Ball goes! I …

About the project: I made a arduino based project which can switch on the light when someone passes by the door to enter the room. it uses a ultrasonic sensor(distance sensor) to identify when someone cuts the wave and enters the room,then the servo switchs then button. This can be modified to turn of the light also,but for that you'll need two ultrasonic sensors to count the people entered the room and how many of them left the room so that it can operate accordingly. (shown in the video) -If interested you can see the making and working video here: -for detailed info please visit my project(same) on instructables.com https://…

About the project: I made a arduino based project which can lock and unlock the door lock when you press button on the mobile.(shown in the video) I made a simple mechanism for opening & closing my pre-installed door latch,and combined it with Arduino Uno via some simple coding. And made a simple app for controlling it through Bluetooth. -If interested You can see the making and working video of it here: -for detailed info see my project on instructables.com: https://www.instructables.com/id/Wireless-Door-Locking-System-Controlled-Via-Mobile Thanks for looking here!!

Hi there guys, i just want to ask if it is possible to extract the ink in magazines, newspaper, or anything that have an ink on it? for recycling that ink so it can be reuse again and again , ahmm for example: i have a magazine here at home, and i want to print something but i don't have enough ink to print it. Can i use the magazine's ink and extract it in the printer's Carthage? or just simply extract the ink in the magazines to be able to use that ink in other purposes? thanks in advanced sorry if i've posted this in the wrong section, i'm not sure though. thanks anyway Cheers

For a grade 10 hum project, I am doing (UN Sustainable Dev Goals) hydroponics. I was thinking "hey, there's a lot of ocean space and sea space, why don't we use that?" I know you can't directly use seawater, but I had another idea. What if I somehow made a little raft with a mesh bottom that uses the evaporated water to grow my plants. The nutrients would be present but not viable yet until exposed to water, and sunlight isn't an issue on the ocean or sea. I'm not by any means an expert and wanted a professional's opinion. Would this be able to work?

First I want to know, what the minimum voltage is needed to make electrolysis of destilled water. I´m using the magnetron from microwave oven, that produces ~800 Wats. I tried to use 3,2 volts (think it has 250 amp) in any solution (destilled water, NaCl salt, sodium hydroxide and basic sodium silicate solution), but any reaction had occured. But I can melt iron screws with it. So I need to know, what minimum voltage is needed to make the electrolysis of Sodium Silicate Na2SiO3 solution (for making Silicon powder). And also to use all amp produced, ~100% or 90%. The second problem is, that the silicon deposited in the cathode can block the curr…

I'm hoping to get some input, ideas and views on my ongoing projects. I'm also hoping that some of this might inspire some similar threads in this area. If more than one of these becomes a talking point I'll (or I'll ask another mod so I'm not involved) to split the topics. Project 1 - the parking sensor (On mobile so no diagrams I'm afraid) The idea was to use a set of ultrasonic distance sensors to perfectly park my car in my garage every time. My car only just fitted. The plan was to have a forward facing sensor, and angled sensor just inside the door to ensure initial line up. Then sideways pointed sensors every few inches to maintain distance fr…

Is it possible to somehow lower the minimum temperature of an ordinary fridge to at least as low as the temperature of dry ice ? If not without modifying it, might it be done by replacing the fridge's liquid from Freon to alcohol, or some other liquid or gas ?

Hey i'm 16 and i've recenty finished this manga called Air Gear and in it were the coolest things ever. They are called air treks and they are a sort of presure controlled powered skates with two large wheels on each feet. So lean forward speed up, lean back slow down. Most of the wirings are in these large wheels. I've read through loads of forums which have all shown lots of progress but eventualy they died down and I hope this one doesn't. I'm about to sart A-level Electronics so i'm hoping to have more ideas to make it real so for now, if there are people who have read this same manga or have seen the anime or just want to see this amazing idea come to life pls join t…

So now I've got your attention its basically a hearing aid, but I'm not hard of hearing. From what I understand, a hearing aid is comprised of a mic and then an amplifier then a speaker. Therefore even if you're not hard of hearing it should be able to boost your range at least. Thing is I'm worried about interference and the noise becoming low quality. Obviously in busy, noisy places, the microphone will pick up all of the sound and I understand that there's very little I can do about this other than not use it in busy places. But you don't actually want the mic so sensitive it picks up every little sound and amplifies it because then the sound you want to hear, most lik…

Hi all, I hope this is an appropriate place to ask this question. Here is my problem. There is a small vent in my apartment's kitchen above the stove that usually doesn't have any air coming from it. Just recently there's a very small amount of air starting to come through it and it smells rancid and might even be cigarette smoke. Either way it can't be healthy and it's making my entire kitchen stink and I can't stand spending time in there so it's disrupting my daily tasks. Basically, I'm wondering if it's safe to seal this vent off somehow and looking for suggestions on how to do so. I don't think the vent is functional because there's just a pitiful flow o…

Here is a suggestion for a simple experiment in cognitive science that a group of people could participate in. There are programs you can download to your desktop computer, laptop, tablet, or cellphone that allow you to solve crossword puzzles. I use one on my Android tablet that provides 3 to 5 new puzzles each day to solve. The program and the puzzles it provides you to solve are free. The app provider makes his money from the banner advertising embedded into the program's display. So here is the experiment: try to determine whether you are better at solving the puzzles with your left eye or with your right eye, but not with both eyes. The images of the puzzles as…

I have done a science project testing how acidity affects the reproduction rate of brine shrimp. I have tabulated my results, but have come across strange data. The weights of the water + brine shrimp have fluctuated and i can't figure out why. How does it fall, because even if they die, they will weigh the same as when the were alive. The water has not evaporated either. Please can someone help? Thanks P.S. I've attached a picture of my table

Hello In new here and I hope this is the right place to post I found this forum while I was looking for some information about what was actually happening chemically when I did this project. I am an art student and wanted to try etching designs into copper by the electrolysis method. My set up was a DCell battery 1.5 volt. connected to a Copper object to etch on the positive end with and another piece of copper on the negative end. I placed them into a salt water solution of 180 grams salt to 500 mls water. I would like to know what the brown and blue stuff is in the water I will attach a picture also I would like to know if any of the chemicals or gas emitted ar…

Hello forum. I've recently decided to store my genetic material in case anything should happen to me, the problem is I do not have the money to store it in a sperm bank, but I have ready access to liquid nitrogen and can whip up ethyene glycol fairly easily as a cryoprotectant, The process itself is fairly straightforward and I'm confident that I can achieve effective results with a bit of trial and error. My question is, when it comes to the dethawing process, I understand I need to wash out the cryoprotectant with a culture medium then separating the culture / glycol with a centrifuge. I'm not sure which culture medium would be the safest to work with and I am n…
