Waves are a relevant part of physics that students find difficult to grasp, even in those cases in
which wave propagation kinematics can be visualized. This may hinder a proper understanding of
sound, light or quantum physics phenomena that are explained using a wave model. So-called ‘human’
waves, choreographed by people, have proved to be an advisable way to understand basic wave
concepts. Videos are widely used as a teaching resource and can be of considerable help in order to
watch and discuss ‘human’ waves provided their quality is reasonably good. In this paper we propose
and analyse a video that went viral online and has been revealed to be a useful teaching resource
for introductory physics students. It shows a unique and very complete series of wave propagations,
including pulses with different polarizations and periodic waves that can hardly be found elsewhere.
After a proposal on how to discuss the video qualitatively, a quantitative analysis is carried out
(no video-…
