View Full Version : Observing Fluids

i've noticed when preparing my coffee in the morning, there's something interesting to look at when you add the cream. i know coffee isn't the best thing to be drinking, but i still enjoy it. :o the interesting thing is when i stir the coffee with a spoon after adding sugar, but before i add the cream. (i add the cream after i stir) as the coffee is still swirling around the cup in a whirlpool fashion, i add the cream. i then take notice at how the two liquids don't homogenize right away, making the top of my coffee look like a grand spiral galaxy. it's amazing how very similar it looks. the long spiral arms that seem to wrap themselves endlessly, the different densities of cream and coffee, almost like a real galaxy. it really made everything hit home for me just seeing it like this. what better way to see the fluidic-torsion dynamics of a galaxy than with two fluids of differing densities merging in a swirling motion. i thought you'd all like to read this and maybe try it yourselves. :)

i wanted to share with you all another accidental experiment i happened to discover. i was cleaning a tall glass that was used as a vase for some flowers with a well known cleaner that shall go nameless (hint: it has to do with oxygen). well i filled the glass half way with hot water and poured the cleaning powder in, then i swirled the glass around a bit to get the powder to disolve before filling it to the top with more hot water. i let the glass sit in the sink for about 15 minutes to let the cleaner do it's job, and by then the foaming action had stopped leaving a white/dingy colored residue on the top of the water. i was about to pick the glass up to dump out the water and wipe it out with a sponge when i noticed a small plume of bubbles in the center of the glass. there was a very small amount of the powder at the bottom of the glass, which came to a blunt inverted point like a champagne glass, that was the source of the bubbles. i just stared at the bubbles slowly making their way to the top of the glass in a 1/2 inch thick, delicate verticle "invisable pipeline" that seemed to exist in the core of the water.
i'm not sure why i got this idea, but i wondered what would happen if i were to wave my hand on the side of the glass to cause the air to blow against the side of the glass. i wasn't expecting anything, but to my amazement, the bubble plume shifted away from my hand! how can this be? there is no way for air to penetrate the glass, the glass never moved, the water was never touched or directly disturbed, yet still the bubble plume moved. i tried it again to make sure it wasn't a fluke, and sure enough, the plume moved again. i tried the same thing on the opposite side of the glass and the bubbles shifted away from my hand's perpendicular motion. it was quite obvious what was going on here, it was my first direct look at the effects of the aether/ether. i was so astonished that i was seeing what was happening that i kept the impromptu experiment going for at least another 15 minutes. i also tried gently blowing on the side of the glass with similar results. i encourage anyone who wishes to see the aether/ether at work to go ahead and try this little experiment.
the glass that was used was about 10 inches tall, and 4 inches wide. incase you didn't understand what i meant about my hint in reference to the cleaner that i used, then by all means pm me for the name. if you guys have another explaination for what i witnessed, feel free to let me know of your ideas. :)
