Rivella surprises hikers with a special echo

A red Älpler megaphone was set up at a vantage point in the middle of the Swiss mountains. Passing hikers had the opportunity to try out the special "Rivella Echo". Anyone who called into the megaphone was then surprised by a drone, which delivered a few bottles of Rivella for refreshment. The whole event was documented with a hidden camera and shared via social media. >>>here>>
