The Science: How Gyroscopes Resist Rotation and Stay Upright

[Norseman]

As the title says, I'm wondering how/why gyroscopes work. Why do they resist being rotated in a direction other than the direction in which they're already being rotated, and why don't they fall down?

I'm not the one to give a detailed explanation, but as a starter you should investigate conservation of angular momentum.
