After my thoughts of flying in the last blog post, I got thinking about the idea of levitation. I started looking into this idea and it actually came up that there is currently a group at the University of Bristol in England that is trying to use sound to levitate objects off of the ground. This idea was first brought up by a Russian physicist, Andrei Geim, who counteracted the gravity on Earth to float a small frog. Physicists are now working to increase the size of what they can levitate to humans and then maybe even cars! They have determined that if they are to place an object at a certain point within a sound wave, the force of gravity and the force of the sound wave will cancel each other out and leave the object floating. The "mini tornado" sound waves work in such a way that it counteracts the gravity it normally feels. Although this has only been tested on very small objects so far, hopefully it will progress to larger items and even humans soon.

This is probably the best thing that I have seen all day and maybe we will see more progress with this and find people levitating in the near future! :D

Until next time,
