The water pressure is due to the weight weight of the water. When the can is in free fall, the water is weightless weightless , so the water pressure is zero, and hence no water is pushed out of the hole! 1) diminish 2) stop altogether 3) go out in a straight line 4) curve upward When a hole is made in the side of a When a hole is made in the side of a cola can holding water, water flows cola can holding water, water flows out and follows a parabolic out and follows a parabolic trajectory.

Then the atmospheric pressure pushing on the liquid in the glass provides a net upward force on the liquid in the straw sufficient to push the liquid up the straw....
