Clever colour changing ink delivers the message

DHL used clever colour changing ink to have UPS literally deliver their message. I must state however that a rep for DHL tells Consumerist that while the shipping company is aware of the video, DHL did not actually pull the prank or have anything to do with the actual production of the clip that has already been viewed more than 200,000 times on YouTube.

“This was not something that was initiated by DHL,” a rep for the company tells Consumerist in an e-mail. “The video was created by an external agency for their own internal competition. We were aware in advance of the intention to use it for this purpose. We were not aware of any plans to share it externally.”

Ahem...yeah, it went 'viral' by mistake, as do most viral campaigns...
