(kazoo noise maker sounds) This is Justin Higgins and today we're going to make a
sweet kazoo type thing out of a some straws and a pair scissors. Now in this build we're going to use multiple straws, and the
reason that I would have multiple straws available is because science is about failure, and if
you make your cuts with your scissors wrong you're going to have to start over. Now in
my area I cannot find straws that are just straight anymore. I can only find
straws they have a little bendy affect to them. That's okay. Just make sure that when you make
your cut you do it on the end that is away from the bendy part. I really like
these ones that have the line on because you just flatten them
out a little bit. And the real trick especially if you doing this for smaller
children is that you want to have both cuts on
either side be exactly the same. They need to be the same
angle and you can't do really minor cuts like
this, you have to do a fairly shallow cut (boop) and then it may help you to put your finger up
next to where the cuts going to take place and cut it again. Now, notice that I have my cuts, that are about the same
spot and that's great that's exactly what you
want to make this work. And then just kinda push your straw back
out. So the trick is to put your lips just on the outside where you cut. Like this. And then blow, while pressing down with your lips (kazoo sounds of awesomeness!) (lower kazoo sounds while gripping with lips, blows HARDER) And.. you can change that pitch of your kazoo by blowing on it an cutting it with some scissors. (cuts kazoo with scissors making different pitches... continues to cut with scissors making faces) (laughs) And the reason that this makes that
sound. (Higgins plays for you some Kazoo sounds) Is because these little flaps that you
created when you cut the straw. They vibrate back and forth like
this going (wiggle sounds) And that's what makes the sound up here at the top, and then that travels
down the length of the tube and the length of the tube determines what the pitch is gonna be. So
don't forget to join me for more Science Fun! every Wednesday and Sunday. And I'll see you guys later
