During Brazil’s opening game against Croatia, Claus Wahlers recorded what his neighbourhood sounded like after each Brazil goal (they won the match 3-1). The video was recorded in Moema, São Paulo, and those loud bangs you hear are fireworks.
The author says there were no big outdoor screenings nearby, just a small BBQ in the building across the street. The cheers you hear are just people watching in their own small groups! Wahlers also points out that you can hear the difference between people watching the game ‘Over the Air’ (OTA) using an antenna versus on cable, as the cable feed has about a 2-second delay.
