Most people have a hard enough time staying in sync when they’re singing together, never mind pulling off a well-choreographed routine with plastic cups at the same time. But pull it off they did — these four Los Angeles-based singers, clapping their hands and shuffling their cups to an incredible cover of Taylor Swift and Zayn Malik’s 2017 hit, “I Don’t Wanna Live Forever.

The video, posted in early March, shows four famous YouTubers — Sam Tsui, Kurt Schneider, Madilyn Bailey and Kina Grannis — seated at a table in a park. For more than three minutes, the camera pans in slow circles around the quartet as they move and tap their cups in perfect synchronicity.

They make it look so simple, but can you imagine how many hours of practice must’ve gone into this whole thing?

The video’s been viewed more than 8 million times and garnered more than 7,000 admiring comments. It’s pretty safe to say, anyone who watches this video is going to be seriously impressed, not only with their singing abilities but the amazing choreography of the dancing cups.
