Guest Wall Bird Posted April 20, 2012 Report Share Posted April 20, 2012 [youtubehd]mODqQvlrgIQ[/youtubehd] Quote This is really simple but has such an awesome effect. Fill a bucket full of water and place it about 5 feet off the ground. Place a subwoofer about 1 foot lower than the bucket. Run a plastic tube from the top bucket down in front of the subwoofer. Tape the tube to the front of the speaker. Then aim the end of the tube to an empty bucket on the floor. Get the water flowing from the top bucket. Now just generate a 24 hz sine wave and set your camera to 24 fps and watch the magic happen. Basically your cameras frame rate is synced up with the rate of the vibrations of the water so it appears to be frozen or still. Now if you play a 23 hz sine wave your frame rate will be off just a little compared to the sine wave causing the water to "move backward" or so as it appears. You can play a 25 hz sine wave and cause the water to move slowly foward.

geosmina Posted April 20, 2012 Report Share Posted April 20, 2012 I guess I have a great idea that combines art, some math, electronics and physics (sound), like the video but synced up with a beat (using some nice subwoofers with killer kicks yo) or something like that to make colored water like dance, yea yea Thanks Haha Confused Sad Facepalm Burger Farnsworth Big Brain Like × Quote Hide geosmina's signature Hide all signatures https://animanoir.xyz/ Link to comment https://forum.watmm.com/topic/73265-interesting-optical-illusion/#findComment-1803054 Share on other sites More sharing options...
Danny O Flannagin Posted April 20, 2012 Report Share Posted April 20, 2012 I saw something very similar to this in physics but instead of a sub, the teacher used a strobe light. Looks a lot cooler here because it isn't as choppy.
