Why do parachutes have a hole at the top?
Parachutes have a hole in the top to provide a smoother and more controlled ride. Without the hole the only place air has to go is around the edges of the parachute. When the chute tilts a lot of air spill out the high side, which is destabilizing. The hole lets air pass through, so there is always a flow into and through the chute, so it’s not trying to spill out the bottom.
