Virtual lemonade sends colour and taste to a glass of water.
A system of sensors and electrodes can digitally transmit the basic colour and sourness of a glass of lemonade to a tumbler of water, making it look and taste like a different drink. The idea is to let people share sensory experiences over the internet.
This shows a very nice approach to reproduce things over long distance by only sending the information of an object. It also could be adapted by many other replication technologies (i.E. 3D printing).
