Angry Birds Space
Angry Birds Space is based on the popular Angry Birds game, introduced in 2009, in which ticked-off birds exact revenge on green pigs for stealing their eggs. NASA seized on Angry Birds Space as an opportunity to educate the public on the law of physics that's fundamental to everything it does: gravity. NASA used the launch of the game to explain the difference between normal gravity (1g), zero gravity (0g), and microgravity, and to point out that experiments on the International Space Station happen in a microgravity environment. In a video demo of what that looks like in practice, astronaut Don Pettitt used a slingshot to catapult an Angry Bird across the interior of the Space Station.
