These jet pilots decided to show off what happens in the cabin at high speed by floating a chocolate bar from one to the other.
The video was uploaded anonymously to YouTube leading to speculation that it may be an advertisement for Snickers - however it could also be to hide the identity of the pilots involved.
Media reports have speculated that the pilots may belong to the US Navy because of the markings on their helmets.
Whatever the origin, the clip is a cool example of the effects of G-force involved in flying at high speed.
Anyone else want a chocolate bar now?
