Stratocaching is an original idea of the association “Žádná věda” (“Not Rocket Science”) from the Czech Republic based on growing popularity of two activities: geocaching and stratospheric balloon flights. The aim is to link science and technology with aesthetic experience and an adventure game – something we call “the magic of experiment”. The first flight took place on November 16, 2013 with 13.000 participants of the game. More than 220.000 viewers watched the live video broadcasted from the balloon on the website of the Czech technology magazine Technet.cz.
