We've talked a little bit about gravity in today's show.
Gravity represents the attraction between objects -- and it acts like a magnet, pulling two objects together. Down here on earth, if i drop a pen it will hit the ground. But aboard the space station's micro gravity environment, astronaut Scott Kelly just kind of floats around.
The band 'Ok Go' may have just defied gravity in their latest music video. The group filmed their creative idea aboard a plane in 'zero gravity'.
They did this with the help of a reduced gravity aircraft. That's a type of aircraft that provides a weightless environment for the purpose of training astronauts, conducting research -- or in this case, making a really cool music video. Jeanne Moos has more.
