The liquid inside the straw vibrates as it gets sucked up, creating a slurping noise. The air inside the straw also vibrates as it is pushed out when blowing into the straw, producing a whistling sound.
Blowing through a longer straw creates a deeper sound because the longer straw allows for a longer column of air to vibrate. The longer column of air vibrates at a lower frequency, producing a deeper sound.
Guitar strings, vocal cords, and tuning forks are common examples of things that vibrate. Vibrations produce sound waves that can be heard by humans.
Some things that vibrate include guitar strings, tuning forks, cell phones on silent mode, and vocal cords when speaking or singing.
Other things that vibrate to produce sounds include musical instruments like guitars, pianos, and drums. Additionally, everyday objects like bells, keys, and glass cups can vibrate to create sound when struck or rubbed.
Some things that vibrate to make a sound include strings on musical instruments like guitars, vocal cords in our throats when we speak or sing, and the diaphragm in a speaker that produces sound waves.

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!

No I think you have got it all wrong. The only things that vibrate are vibrators.

Horses will eat all three of those things. Horses are least likely to eat straw.
