I've featured a collection of videos looking at how different items behave in microgravity environments. The first video does a good job of explaining the concept of microgravity itself, and corrects the zero gravity misconception.
Microgravity is fascinating to me. Being able to push off a wall and fly across a room would be an incredible experience! Knowing me I'd get stuck between walls and have to dog paddle my way to the other side.
