Physics in All Directions

Question #1:
You are driving to a birthday party with a friend. You have a helium balloon suspended between you two in the front seat, not quite touching the ceiling. The road takes a sharp turn to the left, causing you and your friend to feel you are being pushed toward the right. Does the balloon lean toward you, or toward your friend?

Question #2:
You have a toilet, whose water jets are directed straight down the sides of the bowl, so that when you flush, the jets do not impart any rotation to the water going down. When you look down at the water flushing, in which direction does the water spin when you are in Ohio? In Austrailia? If you were at the North Pole?

Question #3:
A 33 foot tall hallow pipe is capped on one end, turned upright, and filled completely with water. Two sensitive pressure guages indicate the pressure near each end. You note that the bottom pressure is almost 15 psi higher than at the top. I take you and the device up in a helicopter, and drop everything from 5000 ft altitude. While falling, you ponder if there has been any change in the pressure gauges. What do you think in this situation?
Bonus: For how many seconds do you think you can remain focused on this problem, starting from when I drop you?
Extra bonus for showing back up at the helipad after I've done my part!
