alright, /sci/, time to put your PhDs to the test
how does this infernal contraption work?

Sound waves travel through the string brah, how do you think guitars work

>> No.3180901

sound waves are, like, just vibrations, man

That shit does not work

CIA used a laser device that was able to detect minor vibrations in the windows of Osama's home. Then they converted this data into assumed sounds and were able to get intel from several blocks away.

Silly strings and time-travel into the past.

What windows? Niggah didn't have no windows.

You have no right to argue me out of normal upper class civil society. I am a normal woman and wife and these people on government PR programs arguing improperly are not. Stupid, flasher and fiendish.No proper attention span. CIA abnormals.

SPIRIT! and if you need a difficult explanation..SCIENCE! both pretty decent. i wonder what the first person to have tried this was expecting, and was it an "in the first place" kind of thing and then when the shit went however it went what their reaction was and why.

1. You talk, creating vibrations in the air, which enter the cup.
2. The air vibrates the bottom of the cup at the same frequency.
3. The bottom of the cup pulls on the string, causing it to vibrate.
4. This vibrates the bottom of the next cup, which now acts as a speaker in reverse of the process of step 1.

The important thing to note is that the sound moves at the speed of light (3 x 10^8 m/s), ignoring delays between the objects, (cup and string, for example). However, it moves much faster than the normal "speed of sound" (340.29 m/s). This effect is called the Doppler effect (because of how the waves compress when traveling at near-light speed).

You are in the same room because the string doesn't reach that far and you look over the cup and say it to them directly.

I truly hope that's a typo.

It isn't, notice how he specifically specified 3 x 10^8. 6/10

>> No.3182331

>>3182283

No, it's got nothing to do with the Doppler effect.

i don't see how this is supposed to be funny. are you just high?
