So I was looking around reading like always , and here I found this little video its an advancement in technology and I must say , I am very interested in this because it brings us closer to UFO like technology in my opinion , but the again , I'm only a college student with big crazy ideas.

From Engadget , this is what i read

Ultrasonic levitation has been possible for awhile, but it's not very practical when objects must typically hover along a single axis. University of Tokyo researchers Yoichi Ochiai, Takayuki Hoshi and Jun Rekimoto have cleared this hurdle with an ultrasonic array that can push items around in 3D space. The machine creates a focal point from a three-dimensional standing wave; users just have to alter the wave's properties to move whatever is caught inside that point. The technique can manipulate a wide range of materials, and it's safe to disrupt with your hands. While the array will need to scale up before it lifts objects much larger than matchsticks or screws, it already shows that we don't need exotic technologies like tractor beams to float things through the air.
