Gosh that looks really difficult! It does make you wonder how the bagpipes every got invented in the first place if you see what I mean!Ok, you asked for it. Don't blame me if your ears bleed.
And whilst we're having a laugh at my expense, here is a video of me playing a home-made set of bagpipes that I made for a uni assignment. I absolutely could not get the thing to tune properly, but I was super-impressed with the drones! As @Ribh said, it's how long the tube is that determines the pitch.
