You spin me right round baby right round-

Crossposter should've used the title from the original OP as it actually tells you what's going on. u/RussianCompSciSpy commented a good explanation of what's going on in the gif:

So this is centripetal force, not centrifugal force. Here's the difference.

Tl;dr: centripetal force is a force going inwards, "centrifugal force" is actually not a real force, but an effect of the objects circular motion.

In physics, when something is undergoing circular motion (think going in a circle or an ellipse around something else), there's two important things at work.

Some force or another that's pulling the object in. For planets in orbit this is gravity, if you tie a ball to a rope and spin it around this is tension. And in this case, this force is the normal force from the stick (essentially because the puck is pushing on the stick, the stick has to push back so that the puck doesn't just go through the stick. Anyway, this force is called the centripetal (center seeking) force.

The object has to be moving at a certain speed or above. This speed is perpendicular to the inward seeking force, and is what most people think of as a "centrifugal force" (which isn't really a force).

To visualize this, imagine you're spinning a ball on a rope in front of you, clockwise. In this case, tension from the rope is acting as the centripetal force. At the top of its path (12 o clock), the ball's velocity (speed with direction) is to the right. It wants to go off in a straight path to the right. In fact, if the rope were to break, that's exactly what would happen. But it can't do that, because it's being pulled in by the tension of the rope. So it has to go in this circular path. When it's at the right edge of its path (3 o clock), it's velocity is now pointing downwards. And left at 6 o clock and up at 9 o clock.

The centripetal force combined changes the direction of the velocity, making it go in a circle. But because at each point along the path its velocity direction is perpendicular to the force (its tangent to the circle, that is, it's a line that only touches the circle once and goes through its current point, Google tangent line for a picture), there's this feeling that objects in circular motion are pushing outwards. They are, but because of the objects momentum and velocity, not because of an outward seeking force.
