What is the spin ? The ball might be 'off center'.

That could be affected by the holes, and I have heard people on youtube
videos say that the noise it makes coming down has something to do with the
holes, too. Just like a pipe you blow over the end, a whistling sound
should be produced by the holes.
I want to see where one lands.
