Billie Eilish's debut SNL performance set the internet ablaze last Saturday night during the premiere of the show's 45th season.

At the start of her hit tune "bad guy," there were very few indications that something unique was brewing, despite a few camera shakes and a couple of nervous cheers from the audience. But then Billie proceeded to dance on the walls and the ceiling in what is believed to be the first performance of its kind on live television.  

Besides a brief look at the camera rig at the tail end of Saturday's performance, few secrets were given away on how SNL pulled off the live Fred Astaire inspired scene. But today, Saturday Night Live finally lifted the curtain on the historic Studio 8H performance by sharing a video on how they achieved the feat, including Billie's original filmed proposal (complete with a tissue box) and rehearsals with the camera rig, which was attached directly to the moving set to create the illusion.  

The side by side diagram of the camera view and camera reveals how SNL achieved live, gravity-defying magic: while the camera view stays the same, the rig and camera move together. In order to recreate this look, the camera used must not auto-rotate (like an iPhone), in live view.

At 17 years old, singer-songwriter Billie Eilish has already achieved musical history. She has the record for the most simultaneously charted Hot 100 songs with 14 tracks. She is the youngest female musician to chart at No. 1 in the U.K. And now, with the help of Saturday Night Live, she can now add defying gravity to her growing list of accomplishments.
