Water + 24Hz Sine Wave...

[alphacat]

So cool.

thats sick haha

[chekov]

would this happen to my wee if i went for a piss next to an rc1 rig?

[Molzie]

woah reverse!

Not unless they were playing a tune where the bass is specifically the same frame rate as the camera filming it and your dick was stuck to the speaker.

sounds do-able

[fractal]

this is sick alpha!

[nowaysj]

sound+water=crazy shit happens

watch it

[fractal]

also sound+(water+cornstarch)=fun!

[lloydnoise]

that was amazing!

[nowaysj]

water+sound=nuclear fusion

[Sexual_Chocolate]

that reverse one was the ting.

[d-T-r]

Would be interesting to see if anyone but the person who made this gives it a go. was always very sceptical about the reversed gravity one to be honest but this one seems more plausible. but i guess acoustic levitation is possible but just not sure if water would float back up exactly back in to the tap? although could be like the optical illusion of car wheels spinning backwards i guess.

Cymatics are cool too

i dont think you understand what is happening

[d-T-r]

enlighten me

was the law of gravity broken in this video? thats all i'm trying to clarify. not whether or not if it appears to be moving backwards . as in are the water molecules actually moving backwards (from floor upwards) in to the tap/filter or is the acoustic influence just making it appear that way? (for the reverse part only)

[d-T-r]

this is cool too : Acoustic levitation of water droplets

the camera is running at 24 fps and the water is being excited at 24Hz so the two sync up and the camera only takes a picture when the water is at the same position. when you lower the excitation frequency of the hose, the water appears to move upwards becuase the camera takes a picture at a slightly earlier position for each frame.

same thing that makes car wheels look like they're spinning backwards on tv

[d-T-r]

cool- and yeah said that earlier about the wheel thing.Was just clarifying the reverse part was based in a cool illusion and black cats and not some kind of actual anti-gravity

[Doozle]

What would it appear to do without the camera, as in the naked eye?

just water coming out of a shaky hose, its all really a camera trick
