That's not faux cotton candy cloud hanging from the ceiling. It is in fact, umm, real! 

That amazing, science meets art man-made cloud called Cumulus II was created by Dutch artist Berndnaut Smilde. It was created in  'Probe,' a test lab for art projects. Smilde was able to create the cloud through the use of smoke, moist and and dramatic lighting.  With all things ephemeral, this magical cloud in a room only exists for a moment before it evaporates into the ether.
