OK Go released a music video filmed in zero gravity.
"Upside Down & Inside Out" used complex math to defy gravity on a plane. No green screens here.
ABC reports it's the first original music video shot entirely in zero gravity.
"Tim, why are you playing with gravity?" an OK Go member asked in a video.
"Well, for one, gravity is cool," another OK Go member said.
They collaborated with a Russian airline and a space training center.
The group is known for another music video. Some say "Here It Goes Again" revived music videos in the YouTube era.
They've done other elaborate videos since then.
They made a giant Rube Goldberg machine with the help of engineers.
They collaborated with the Muppets, too.
And they've performed under water.
This video includes clips from BMG Rights Management.
