The beach party has moved down to the sand. A boardwalk strung with coloured lights runs all the way around it, the moon hangs low over the sea, and glow bracelets lie scattered everywhere after the last show. Pixel Dua Lipa starts dancing across the beach, a few friends fall in behind her waving glow sticks, and before long everyone is calling it the Glowstick Groove.
Every bracelet she picks up brings another dancer into the line, and the groove gets a little faster with each one. The boardwalk edges the sand on every side, so one wrong step ends the dance, and so does tripping over the very line she is leading. Once in a while a golden microphone turns up on the sand for a few seconds, worth a big bonus if she reaches it in time. How long can the line keep dancing before sunrise?
