Possilbly the cutest little invention of 2012, the Fogring mini aroma diffuser and humidifier just needs a glass of water and a USB port to work. From Neotizen, the Fogring is a portable sub-miniature lightweight USB ultrasound mini humidifier that floats on water. As it does not have a fixed water tank, it is able to float in any type of container with water. It is easy to clean and prevents the propagation of germs, and is also able to be used as an aroma diffuser.
