Science illusionist Brusspup used a subwoofer to create the illusion that water was some how dripping up, defying gravity. By changing the level of hertz from the speaker, and setting his camera to 24 frames per second, he seems to have the ability to change the direction of flow of water.
Of course, it’s all in our heads. The water is flowing as it should. The video is featured on KnowYourMeme.
