There are a variety of ways for making sounds from ordinary glass and plastic bottles and has been a favorite of students for years, here are a few additional activities to investigate about the sounds made by either striking the bottle to make it ring or blowing across the mouth (Helmhotlz resonator) to make sound by vibrating the air inside the bottle, either way it is an investigation that anyone can make. Additional ideas are included to take bottle sounds to the next level

the school is 7th through 12th and has about 800 students, busses also serve the elementary school which has about the same number of students

Thanks for showing so many non-obvious results! When you increase the air pressure, do you think it's the rigidity the pressure's creating in the plastic that's actually the reason for the higher pitch? When you set them down, they sound "tight". Also, the explanation for why waves are set up seems incomplete. Why the pulse of pressure/oscillation? Turbulence?

@Bendigo1 2 жыл бұрын

The density of the liquid and material of the bottle along with setting it on the table or changing how it is held changes the resonant frequency of the bottle, it will flex more or less with each change. Changing the resonant frequency of the bottle changes how much pressure the incoming air can be before it is forced back out. Blowing across the top of the bottle is simmilar to Blowing into a whistle. It causes an oscillating pressure wave, when the pressure in the bottle is greater than atmospheric pressure, air starts to escape, but is cut off by the air being blown in, so there will be a rapid pressure change creating the sound. If that makes any sense. I am not the best at explaining things.

07:20 There's a type of flute with a stick (slide whistle) at the bottom. Lowering or raising the stick lengthens or shortens the air column hence changing the pitch of the whistle : kzfaq.info/get/bejne/ZpxkbNOn2sfFnZs.html kzfaq.info/get/bejne/i7qdlqpj2760lKc.html Indian Rajasthani Double flute: kzfaq.info/get/bejne/jrual5OBrN7XaYU.html

Dear Mr. Yeanny, I wouldn't normally point this out on a YT video, as it may be too pedantic (use of the word "damping"), but as yours is a science-focused channel, here we go: Mechanical resonance-effects are dominated by _three_ effects - related to inertia/mass/kinetic energy, related to stiffness/elastic modulus/potential energy and related to dissipation/damping/entropy. These three, in various contributions, affect resonance. Mass and stiffness predominantly affect the frequency and the damping affects the "sharpness" of the resonance and the persistence of oscillations. In the water-filling process you mention that the added water "damps" the ringing tone 1:48 . This is imo misleading. Its effect is due to the added mass. Damping is not significantly changed. Just as when talking about energy, it is crucial to discern between "Force", "Energy" and "Power" - these have three distinct and specific connotations, the same holds for Mass vs. Stiffness vs. Damping . Excellent demos with the various gases! :)

@YeanyScience 2 жыл бұрын

Thank you for pointing out the error, I got caught up in the demonstrations and didn't put enough time into making sure I had explained it correctly. Damping would be occurring after the containers are struck and would not be explaining the change of pitch. I will write a correction in the written explanation.

@raykent3211 2 жыл бұрын

I got a big surprise when I dangled an alu tube in water and hit it. My brain told me the pitch would go up as the air column shortened. It went down! I stood there a while asking myself how I got a degree in physics, then spent an hour on the internet and still have no answer. The nearest i get is that gently exciting the air in a tube gives a pitch that depends on the length/volume of the air column and very little on the meterial of the tube. But striking the tube doesn't depend much on the air column, much more on the material of the tube. I still dont understand....

@@raykent3211 Thought-experiment: Imagine you take a tube of aluminium, thereafter a tube of titanium, both of the same shape. The "whistle" working of both will be the same, while the hammer working will yield a higher pitch for titanium. Do you agree?
