Need some help for a science project.

Falchion:
I got the red wire out successfully, and when I put it into 5V, it felt pretty loose. Is it supposed to feel that way?

Note that the arduino can sometimes, depending on the servo, just about manage to power one. For the multiple ones you're going to need, you'll need a separate power supply for the servos. DuaneB's tutorials mentioned above should help you with how to wire them up.
