EXPLAIN THIS [UPDATED]
A few minutes ago I was making chocolate milk (yes, I know, I’m 5 years old, feel free to insert witty banter). Well, as I was stirring I realized that the frequency of the sound I was hearing as the spoon hit the side of the glass decreased with increasing rotational velocity of the fluid. I have yet to come up with a satisfactory explanation for this phenomena, though I’ve only thought about it for about 5 minutes now. Thoughts?
Cheers.
UPDATE: Verdict: lame. See comment #1.
ah, not as cool as i thought it was. i think it’s clearly a simple surface-liquid contact area effect. as the fluid is stirred, contact area with the glass increases, inducing the decrease in frequency, much the same as if you had simply filled the glass just a little more.
did a series of experiments with varying fluid heights and this seems to account for it.
nice to see you are keeping yourself busy with the deep questions of the universe! I had a great explanation all worked out but your comment would have put it to shame…how’s everything going?
Although isn’t it a little different than filling it up more… one changes surface area only and the other changes both volume and surface area.
Also I think we should go back to the running in the rain problem as long as we are being practical.
@afischer yeah probably should revist that one.
@kevin yo man … yeah chocolate milk requires much study. i’m up in alaska for the next 2 weeks but things are pretty great … i’ll be in touch when i get back.
have you factored the force that your hand hits the side of the glass. Without a robotic arm that can strike the glass at a consistent force throughout the experiment which will allow frequency to be measured more accurately, you must discredit all data collected. Besides, being jacked up on “the Q” from Nestle’s zestful powder has prohibited logical brain function.
…how sweet is Alaska huh!? mail me crab
Up in Alaska??? …this close to election time? Is someone sent to do opposition research perchance?
