When BTS performs at concerts, their light sticks, called the “ARMY Bomb,” can sync with the music and lights on stage 🎵. This happens because the light stick has a special device inside that can connect to a Bluetooth signal sent from the concert venue 📱.
The Bluetooth signal tells the light stick what color and pattern to show, so everyone in the audience has the same light effect at the same time, creating a beautiful and united display 🌈.
During the concert, the lights on the sticks change color and flash in time with the music, which is controlled by the concert organizers using a special system 🎶.
This synchronization makes the concert feel more exciting and connected, as all the fans are part of a big, colorful show together 🎉.
The light stick also has a special button that fans can press to send cheers to the performers, which can be seen on a screen at the concert, making the experience even more interactive 📺.
Overall, the BTS light stick is a fun way for fans to be part of the concert and show their love for the group 💖.
