This beautiful video which was part an internal creative advertisement competition held by a popular German ad agency, Jung von Matt has tricked UPS workers to deliver large boxes with a text ‘DHL is faster’ on them.
This was made possible by some creative thinking as they used a thermal sensitive ink on the large boxes which turns black when frozen to a very lower temperature and vanishes at normal temperature. So they froze boxes which read ‘DHL is faster’ and left them for delivery via UPS and when they were actually delivered, the ink vanished and UPS workers were actually holding those large boxes on the streets trying to deliver.
While everyone thought this was a marketing stunt pulled off by DHL themselves earlier, it was later revealed that they were not part of this.
One hell of a job that!
