Unmanned aerial vehicles (UAV) are getting so small you might mistake them as flies. Be careful not to swat one of them if they pass between your face and the book you are reading.
Yes, they are so small that they can actually fly into places never thought possible, like your mail box, handbag, or coffee cup.
Researchers from the Swiss Federal Institute of Technology just created unique mini-UAVs for surveillance performances. Their rotor spars snap off so you can also carry them in your pocket protector. The tiny drone features 0.3mm rotor arms that locked in place with a set of magnets in each joint.

Be careful before you get undressed. You never know if you are being recorded. The whole world is changing. You are absolutely not alone anymore.
