Well, it probably doesn't have to point *straight down* in order to get
leakage.  Say, for sake of argument, that any orientation of the hole
pointing +/- 45 degrees of straight down will result in leakage.  So 90
degrees of the hole's orientation, out of 360 degrees (one-fourth) will
result in leakage.  What's the chance that *no* hole will fall in this
range?  Assuming the orientation of each lifter is independent of the
others, it's 3/4 raised to the power of 8, or (approximately) 10%.  So the
chance that at least one lifter will fall in the "leakage" range is 100% -
10% = 90%.

Pretty good odds.
