different liquid detection sensor

I am building a biodiesel production system. at different points in the process, a tank will have different liquids in it (sometimes more than 1 type, separated out). for instance, there is a point where glycerol sinks to the bottom, while biodiesel floats on top. what i want to do is drain the glycerol from the bottom of the tank (via electronically controlled solenoid valve), then when a sensor detects a change in material (biodiesel), shuts off that valve and opens another (final product tank). for the life of me, i cannot find a sensor that will do this for less than $100. preferably, i'd like to spend less than $30. i can work with a resistive type or voltage type sensor. i just need to be able to make that distinction of material change... any ideas? THANKS!!!

liquid motion timers (aka density timers/toys) What's in them?

You know those liquid motion toys you often find at places like Spencer gifts in which a denser liquid (usual bright colored) drips down onto a spiral and you can watch this discrete bubble ride on down? I'm wondering what's inside them and if its feasible to make your own. I've heard lots of things, that the clear liquid is usual a light oil and the colored part is water. I've heard the reverse, I've also heard that there is no water in these things that both are different oils.any help would be appreciated. if your still wondering what im talking about heres a place that sells them : http://www.officeplayground.com/spiraltimer.html

Liquid nitrogen at the doctor

No real point to this but I wanted to post anyways because it is kinda cool.  Went to the doctors office with my wife today because she had this spot on her ear that was bothering her.  Well the doctor wanted to freeze it with liquid nitrogen to get rid of it.  Well of course my ears perked right up because to be honest this was going to be the same time I was even in the same room as this *cool* stuff.  I asked her to pack some up for me to take home.  She laughed and said she wished she could but did not have anything to transport it with.  But she brought in a styrofoam cup about half full of it.  She used a quetip to apply it to the spot on the ear three times.  Then handed me the cup and said "I know the geek inside you wants to play with it.".  Our doctor knows us well.  But the bummer part was that I did not have anything to put in it.  So since the only thing I had to freeze was myself I put the quetip on my finger.  ......Yes this hurt.  But it was still fun.  Then I was left to just watch it boil and then blow on it once in a while.  But when we were leaving I handed the cup back to her since I figured I could not leave with it and it was almost gone anyways.  Then she said something she liked to do with it was to pour it on the floor.  I was pretty cool to watch the "fog" it kicked up and listen to the floor crackle. Anyways, that is my story of the day.  I did not get to do much with it, but it was still *cool*.

A custom timed release liquid dispenser....

Hi everybody! How are we all? I'm working on my latest project sending a weather balloon to around 100,000 feet and capturing the journey on camera. I've done it before as you may see on my blog www.joshingtalk.com. Anyway, my newest project involves making art at around 100,000 feet and this is where you could help! I know this could be done fairly easily but I do not have the knowledge to do it. I need a container that dispenses a small solution of liquid every 15 minutes. Now I've done a lot of research and this is the best I can come up with: http://www.amazon.co.uk/Fishmate-Automatic-Aquarium-Fish-Feeder/dp/B000YK5W18 It's gravity action, many compartments, on a rotary basis, at timed intervals BUT it will only allow for a few rotations over several hours. I'm looking for 8 rotations over 2 hours. I also checked out water timers but they seem a bit more complex. Maybe you have an alternative idea? Maybe it's 5 minutes of fiddling for you? It feels like to the right person, this should be fairly easy to overcome. I'm based in the UK and if you would like to help me with this project, I'd love it and be really appreciative! It's all good fun and you could see your device hovering at 100,000 feet.... Many thanks, Josh Update- Another vital thing I forgot to add is that this device needs to weigh under 200 grams.

Would this floating idea be plausable?

Basically, I was thinking in my sleep as I usually do. I thought about how less dense things float on top of more dense things. And this got me thinking towards this: Are there any gases that are more dense than the human body? If so, we could float on this particular gas (with gas masks or oxygen tanks of course). This also led me to think about: Are there any liquids which are lighter than air? We could have a swimming pool of sorts that floats on the ceiling. All we would need is the right chemical. Any scientists out there? (I know it is unlikely as states of matter generally mean that in terms of density, Solid>liquid>gas.

How to get liquid with bubbles running through surgical tubing? Answered

Hello all, I may just not be searching the right terms, but I can't for the life of me find a way to have colored liquid with bubbles in it run through surgical tubing. (Basically, the bubbles show that the liquid is flowing.) I've seen this effect in movies using smaller diameter tubing and also in larger tubing in the frame work of old style juke boxes. For halloween, I'm thinking about a throwing a mad scientist party and using a black light lit  fluorescing liquid In the tubing. Bonus points if it's portable for the costume! And yes, I haven't really played with pumps before, so if most do this out of box, please be kind. :) many thanks!

Best way to lift a liquid using heat? (SImple pump designs)

I'm overhauling the design of my solar concentrator and now need a good way of lifting a fluid, so as to pour it into a waterwheel and provide rotation. I have a little solar concentrator and boiler to generate heat or steam. What's the best configuration to give as high a rate of flow as possible? I'm hoping for something in the range of 500 ml per minute, rising about 30 cm. I've briefly played around with the attached setup, which is a very basic bubble or airlift pump,  The black is my wheel, the blue a reservoir for the fluid (ethanol), the white is the boiler putting out steam (ethanol vapour) and the light blue is a mix of the liquid and bubbles of vapour which rise up the pipe and re-enter the wheel. It actually works ok, but even optimally only gives a third the rate I'm after. If necessary I can grab some valves from old bike innertubes, or other basic materials if they'll help. My previous design was to have the bubbles of steam going directly into the wheel, which was filled with ethanol. This works but requires heating 3 litres of ethanol to just under boiling. Not impossible but a bit of a hassle. I'm hoping lifting a liquid instead will be a bit easier.

strange fluid inside a rear projection tv i was pulling apart? Answered

So i was disassembling a toshiba rear projection for the fresnel lense, and figured i'd pull the rest of it apart and see what parts i could salvage, i got to the gun assembly (i think its called that) and was pulling one of the guns to bits to salvage the lens mount and discovered there was some sort of liquid between the gun and the lenses, it smelt strongly like alcohol and burnt when i held a flame to it long enough, i got some on my hands and my hands started getting a burning sensation so i washed it off and stored it in an icecream container can anyone tell me what the liquid is? why is it inside the tv/projection guns?

In Spain, looking for clear teflon tube for a lightpipe.

I guess this question has two parts. I'm prototyping a solar energy device, part of which is a light pipe to transport the collected solar energy, about 300 - 2500 nM. I'm planning on making this from a flexible tube filled with a highly refractive liquid, stoppered at each end with clear plugs. It looks like the materials I should be using are: Tube: Teflon (PTFE, FEP, AF 1600, AF 2400) in that order of desireablitity, lowest to highest. The AF 2400 has a refractive index of 1.29, which is the lowest of any polymer. Apparently. Core: Mineral oil / liquid paraffin. Plugs: Acrylic or normal glass. Thoughts? Also, where would you suggest I try to find these? (I have the mineral oil already) Keeping in mind that I'm in Madrid, Spain. Getting this to work would make a huge difference to solar microgeneration, as transporting the energy is currently a bit of a nightmare. Thanks heaps, Daniel.

Boiling a fluid to make a inverse water wheel?

Ok, how about this; Submerge a waterwheel type structure with cups facing downwards on one side. Under the cups you have some kind of heating element. The fluid is methanol or some other low boiling fluid. A very small amount of heat from the element will produce bubbles, which rise and are caught in the cups, the wheel turns and can generate electricity or whatever. I'm using this principle in another application, but thought it could be quite an efficient means of generating electricity from heat. If the meths is sitting at forty something degrees and boils around 50, it shouldn't take hardly any energy to tip it over. And since you're effectively generating force from gravity (the weight of the fluid on the other side of the wheel) you're kind of getting ten times your force back. ie producing one litre of bubbles will give you 9.8 Newtons of force (for water, 8ish for meths). So (excuse my dodgy maths) 125 litres of bubbles in an hour would give you 1 kiloWatt hour? One cola bottle per minute, doesn't sound very much and that much energy could easily be produced through concentrated solar. Slight risk of explosion... How efficient do you think it would be, overall?
