Why does a shorter straw have a higher pitch?
It is the air vibrating up and down the straw that made the sound. Explain that as the straw got shorter, air vibrating up and down the straw traveled a shorter distance causing more vibrations per second. This increased frequency caused the pitch of the sound to get higher as the straw got shorter.
How do you make a duck sound like a straw?
Cut the two edges of the flattened end of the straw into a central point. Slide the pointed end of the straw into your mouth and blow hard into the straw. You should be rewarded with a duck-like call. For different sounds, cut the straw shorter.

Can you teach yourself to whistle?
Everyone can learn to whistle. It just takes time and a lot of practice! Learning to whistle takes a lot of trial and error, so don’t give up. Once you get the hang of whistling by blowing air out through your lips, you can challenge yourself to learn how to whistle with your fingers in your mouth.

Why don’t you hear anything in space?
No, you cannot hear any sounds in near-empty regions of space. Sound travels through the vibration of atoms and molecules in a medium (such as air or water). In space, where there is no air, sound has no way to travel.
How did you generate waves in a straw?
When the straw model is twisted, it creates a helix-shaped wave. You can see the troughs, crests, wavelength, frequency, and amplitude. When the wave is tapped, you can see the vibrations move through the model. The wave travels down the straw model on one side and reflects on the other side.
What do you think will happen if you decrease the length of the straw?
Blowing on the reed causes the straw to vibrate. A standing wave pattern is created along the length of the straw, which we hear as sound. As you shorten the straw you shorten the wavelength of the standing wave pattern and therefore increase the pitch of the note.
How do you make a duck whistle?

Is straw edible?
Straw is mainly used for bedding though it can also be used as mulch. It is edible, but not very tasty and not very nutritious either.
What was produced when you tapped the straws?
When adjusted properly, the flattened end of the straw vibrates as the air you blow flows over them. These vibrations are passed on to the column of air inside the straw. The vibrating air produces the sound based on the length of the straw.
