What you need for a flash mob

A flash mob needs more than music and dancers. You will need a reliable way to play the track, mark the space, register participants and keep everyone informed on the day. Plan power backups, signs and water before the final rehearsal, because these are easy to overlook and difficult to replace at short notice. This shopping list covers the practical equipment and serving supplies needed for rehearsals and the performance itself.

Tips

Bring at least two spare battery sets for each battery-powered speaker or microphone, and fully charge every music player and power bank the night before.
Take one registration table, a set of chairs for the registration point, directional signs and wristbands. Pack these together so check-in can be set up before participants arrive.
Allow one reusable cup per participant plus 10% extra, and prepare enough water for the rehearsal and performance. Water jugs, coolers and thermos flasks help keep drinks available without repeated trips.
Pack extension cords, power strips and charging cables together, then test the complete sound setup at least 60 minutes before the flash mob. Keep the music player and a backup device ready.
Bring chalk marking, warm-up cones and yoga mats for rehearsals, plus colored ribbons or an announcement board to make meeting points visible. Put these in the vehicle first so they are not left behind during setup.
