The comments are very spirited in some of the video threads.   One commenter had this to say:

love these videos. I can imagine them being used in science classes to test, discuss and disprove or rather show why these don’t actually work. I love reading the comments and seeing how people don’t get that that’s the point of this whole channel. People in comments can really lose their perspective and get bent out of shape!

No matter what side you are on, either a fan of the videos or not, Valeriy Ivanov definitely put in some solid effort.

Feel free to comment with your ideas on these types of devices.
