Is there anything more terrifying than water rippling due to the footsteps of a nearby dinosaur?

The studio behind Jurassic World bets not. Universal is building up anticipation for the upcoming film’s first trailer with a teaser video.

The clip depicts two glasses of water rippling as a dinosaur stomps around the vicinity. Not only is this a reference to the original Jurassic Park film, but it appears to be a clip pulled from the 1993 Steven Spielberg picture. Watch:

This particular clip debuted on Universal Spain’s YouTube channel. Are there more to come? Did Universal Spain release this on their own for fun? Will clips from the original Jurassic Park film appear in the full trailer? Time will tell.

The first full Jurassic World trailer is due out Thursday, November 27. A viral site has already launched, http://www.masraniglobal.com/, which appears to be for an oil company who owns the Jurassic World theme park.
