Oh You are lucky man. Kids don't do this at home. Motor draws a lot of current and can(will) easily (especially stalled) burn Your Arduino. You have to use, transistors, relays, or special drivers.
The 5V line comes directly from the voltage regulator or, in this case, the USB, which means it can easily supply a couple hundred mA without problems. If he were to connect the motor directly to a PWM output of the Arduino, THAT would be bad.
Hi, need some urgent help, I have an arduino uno and a micro gear motor from pololu but i have to be able to control its direction. Do you have any idea how to do it? A motor driver board? Does Pololu have it?
A DC motor like the one in this video will run in reverse if you apply V+ and GND to the opposite pins. To be able to switch directions without connecting or disconnecting wires, you'll want to use an H-Bridge, or a motor driver board that includes an H-Bridge.

+IG G 360mA stall current on these motors. The internet says an Arduino has 40mA MAX output. Surprised something didn't go wrong here.
+Average Man vs Pi Wait...he's using the 5V line, isn't that a bit more forgiving than a standard pin?

How much load do you think this could support? 5 lb, 50 lb, 100lb?
That's a micro video showing a micro motor.
what's the RPM?
could you maybe tell us what the gear ratio is?
