Re: The Volkswagen saga -"I can float a steel needle in a glass of water."
Also, oh no you can't. You can make use of surface tension to prevent a steel needle from being wetted, so that it stays on the surface. That is not floating. Let me add a tiny quantity of detergent and your steel needle will suddenly sink.
Why don't you get one of your hundreds of physicists and engineers to explain these things to you before posting?
