Title: Jets from a bottle fountain

Description: Water jets form from holes in the side of a bottle. The water exiting the bottle will have a constant horizontal velocity that depends on the depth of the water above the exit hole. Once the water leaves the bottle, it will accelerate downward due to gravity: hence the water will follow a parabolic path. The hole farthest from the top surface of the water will have the greatest exit velocity, and hence the widest parabola. As the water level drops, the exit velocities from all the holes will decrease.
