dude, you really gotta credit the video you use. in this case, ill tell you where the videos came from. the first video is called "magnetlike slopes" by kokichi sugihara, a Japanese mathematician who creates beautiful illusions. kzbin.info/www/bejne/nnK7nmOaftqsq8k the next few videos are from a popular youtube channel by the name of "brusspup". kzbin.info the last ones seem to be original videos by the creator, as said in the description, which is probably the inspiration to make this video.
