weird experiment

[arkain101]

I was messing around with an experiment and in the process had some strange things occur.

My experiment was to put a layer of cooking oil on water and submerge a strong magnet between the layer of water and the layer of oil and set it to freeze and see exactly what structure the ice would take when it freezes and see what kind of effect the magnet would have.

In the process I made a strange discovery. Sinking bubbles.

I was injecting air into the water and it would bubble to the surface and disperse. Then I injected a larger bubble and it went to the surface, then an equal sized bubble formed and sunk slowly down through the oil and stopped where the oil and water meets. The bubble(s) sit half way into the water and half way into oil. I watched these bubbles and after awhile they start collecting to any other bubbles in cirtain forms. With enough small bubbles and medium sized bubbles it forms crop circle like formations between the oil and the water. After some time these bubbles dissapear out of existance and nothing rises to the surface. The only thing I was able to see was a miniature bubble barely visible to the eye that may or may not have come from these vacume voids in the water - oil meet.
I took this further and put the mixture into the microwave and heated up the water. The water quickly began to want to boil. There was a floaty in the water and the boiling began to start to come from the floaty. I took the cup out and the water was boiling and virtual bubbles would start sinking down through the oil into where the water and oil meet, again I watched as the bubbles appeared to bond in ways they wanted to. If there was a small bubble attatched to a large bubble and those two were moving towards a large center bubble it would steer and pivot to fit before it came in contact with the other bubbles. I had some strange spiral shapes form.

It appears that whats happening is somehow water gets pushed up through the oil from the boiling or the injection of air. When it reaches the final surface the water surface sphere remains its shape then sinks and displaces its volume somewhat equally between the water and the oil.



I doubt this is anything new.. but it is really quite interesting.
I tried to inject air into these fake bubbles but the air would form a bubble inside the fake bubble and float to the top and disperse in the atmoshphere.

I have been messing around with the experiment some more.


The bubbles appear to be water for sure. Although it seems as if these water bubbles are actually hollow and have a minute amount of air inside them. The surfice tension seems to remain as a hollow sphere in some cases. Like soap film on a bubble maker, the bubbles between oil and water have elasticity and strength.
I also noticed the odd time a large bubble (sphere of water) finally soaked in and disolved into the rest of the water that sometimes air bubbles would be released through the layer of oil. The air bubbles leave this nearly invisible jet stream that almost seems to be water streaming out or possibly bubbles.

I found an even less dense liquid and poured a small amount on top of the oil. It sinks in like a weight on a trampoline and has a circular top shape to it. When you put small bubles inside this little dentation. The liquid will move around and usualy go to the sides. When it moves the minute bubbles will move around in the dentation, displaying the rolling form the molecules take as it moves around on top of surface tension. It is quite a complex motion the bubbles follow and appears to follow the same pattern.

With just the oil and water layers. I would drop small bubbles of water into the oil and they would sink and sit inbetween the water and oil. Probably because the outter surface of the water bubble had oil on it and prevented it from going into the water at the bottom. The thing is though. These bubbles that are squished in this low friction enviroment are attracted to eachother. The bubbles dont really choose to be on the center or the side they just prefer to head towards another. So this high pressure bubbles want to be together. Oddly enough this is how my gravity idea is basically modeled.

If you spray a jet stream of water hard into the oil-water layer many small and big bubbles will form. The bubbles will form small little galaxy like structures and it is acutally quite interesting so see how they will form each time before dissolving away.

Has anyone tried this experiment?

What do you think the jet streams that follow small air bubbles that travel upwards through the oil to surface is all about? Once the air is gone there is a whitish stream that floats around.

inteeresting, do you have a webcam to take pictures of it?

[arkain101]

negetive.
If you decide to give this little test a try. Just use your trusty siringe for haroine and other drugs (jk) for injecting air and liquids into the mixture where you want. Use cold water. Hot water speeds up everything and makes for less observable results.

what specific type of oil? does your city have hard water or soft water? Trace contaminants? (eg winnipeg has asbestous pipes which seep it into the water supply,gets it's water from a lake, minimal treatment in that chlorene added to kill bacteria and such.)

[arkain101]

Our water is underground spring water from glaciers. So i suppose its just average, fairly mineralized water, nothing much though. No treatment.
olive oil.
althought i dont think its that important. Basically just get some water and oil and have fun.

ooh vegtible oil., I was thinking automotive/mechanical oil, maby a synthetic. have you tried it with those?
