first step:
Take a straw, bend it along a quarter, flatten the head, and blow hard, the straw will make a sound.
Step 2:
Slowly cut the straw short with scissors. As the length of the straw changes, the sound will change in pitch like the range of the flute produced by pressing the hole of the flute with your hand.
third step:
In this way, this little experience, which can be regarded as a mini game, is finished. In the past, we threw away the straw after we used it up. After learning this, we can make full use of it, turn waste into treasure, blow out different sounds, and give ourselves stress reliever.
Note: One end of the straw must be flat.
