One straw because there is a gap between the middle of the two straws which lets in a lot of air allowing you to drink less

When you blow on the end of the straw, the two pieces of the tip vibrate together. This makes a vibration, which is necessary to make sound. But the tips don't just vibrate at any old frequency. No sir! The vibration travels down the straw, and reflects from the end. This sets up a wave in the air in the straw; the vibration will bounce back and forth between the two ends. It is this vibration that you are hearing! Changing the length of the straw (by clipping it off, or by making a straw trombone) changes the time necessary for the vibration to travel up and down the straw, and so changes the pitch. And making a hole in the straw, so it is like a real flute, lets the vibration bounce off from where the hole is, which will also change the pitch!
