In a pretty incredible demonstration which you will have to see in the video, the demonstrator shows water being carried by this quadcopter and not falling out of the glass.  Not to mention the speed and turns which this thing takes would make you think there would be plenty of splashing.  He explains that the quad structure of this device more evenly distributes the gravitational forces on the container thus keeping things more than you would think.

One of the commenters Jerry Simmons states:

I’ve never been truly blown away by technology for a long while now, but this just about did it. Phenomenal.

It is incredible and in the future medicinal deliveries, rescue missions and simple everyday shopping deliveries will be simplified by such technologies.  Even a new show called “Air Battle Bots” could be a part II to the popular show 🙂

We hope you enjoy the video.
