      Following the centripetal force equation: F = mv^2/r, we can see that the variables which could be investigation are the mass of the revolving object, the speed of the revolving object and the radius at which the object is revolving. This experiment investigates the affect of changing the centripetal force and measuring the time taken for ten revolutions.

        Director: Alex Mendez Giner Executive Producer: Juan Bernardo González Through a downpour in the middle of the night, a couple travels in a lost highway in the middle of nowhere. Unexpectedly, the headlights of their car illuminate what appears to be a crime scene: beside a car stopped in the middle of the road, a man is dragging a body on the asphalt. At the last second, the couple manages to avoid the accident dodging the man and stopping the car few feet away. Being discovered, the man drops the lifeless body while a woman gets off the vehicle and violently walks towards the couple. With no time to recover from the incident, the couple sees the strange woman coming towards them and decidedly throws them a bag full of money. Centripetal is a story full of fear and bad decisions, in which the only way forward is to start all over again.

            "Black Hole" is a series of images, which shows paint modeled by the centripetal force. The setup is very simple: Various shades of acrylic paint are dripped onto a metallic rod, which is connected to a drill. When switched on, the paint starts to move away from the rod, creating these amazing looking structures. The motion of the paint happens in a blink of an eye, the images you see are taken only millisecond after the drill was turned on. To capture the moment, where the paint forms that distinctive shape, I connected a sensor to the drill, which sends an impulse to the flashes. These specialized units are capable of creating flashes as short as a 1/40000 of a second, freezing the motion of the paint.
