What are the short orange markers at each of the end zone four corners in American football called?

The short orange marker at each of the end zone four corners is a pylon. The pylons visibly mark the area where end zones are located on a standard football field. The four bright orange football pylons keep the corners of the field easy to spot from a distance, and they have a weighted bottom to hold them securely in place. All the line and end zone markers are made from a tough vinyl-nylon blend material. They also have a soft poly foam core to help prevent personal injuries.

In the game of football, touching the pylon with the football is fair and counts as a touchdown (score). However, the ball must always cross the plane of the pylon. If only the player's body crosses the plane of the pylon or touches the pylon, a touchdown is not allowed/recorded. The pylons are used by the officials in the National Football League (NFL) in professional games to be able to see if a player truly breaks the goal line with the ball.
