The rules state you have no access to water or a vaccum, the tools listed are irrelevant, so pee the ball out... The average human has plenty of urine in them to float the ball out; it only requires 155mL and the bladder has over that much easily...

Liquid...those type of balls will float. Any type of liquid will do. If there isn't any liquid available and for some reason you had a air pressure hose you could try it; use enough air at the right angle and it will pop it out. But liquid is more practical and easier.

Some interesting responses, however they seem a bit complicated. Personally, I would simply pour water into the pipe until the ball floats to the top.

You could blow air over the top of the pipe using some sort of compressor. The faster the air is moving, the lower the atmospheric pressure outside the tube will be and therefore air will attempt to escape from the pipe, thus causing the ball to rise to the top.

Fill the hole with water, the ping pong ball will float to the top.

A vacuum cleaner will remove the air from the tube, but not lift the ball up through it.
