Handmade straws: Teach you how to make musical instruments with straws.

This is Mr. Han's new invention, the most common thing, as long as it is processed and created by Mr. Han, it will become a magical instrument. Be worthy of being the father of piano! Take McDonald's straw as an example: primer, also known as whistle, mouth, primer and tube are all the same straw. Cut a three-centimeter-long straw, heat-set it on the boiling pot cover, press both sides of the air hole with a cloth pad to keep the root round, and cut it off at one time with a nail clipper. Enlarge the root hole slightly, so as to insert it into the tube smoothly. Opening holes: Make the Tula as long as the straw, mark the holes on one side of the red line or yellow line of the pipe body, make the two-inch nail cap into an oval shape with a wrong knife, wrap several layers of paper around the nail tip to avoid burning hands, burn the middle of the nail with a candle, burn the holes with the nail cap, wipe off the melted plastic stuck to the cap every time a hole is burned, and then burn the next sub-hole. Everything is online, and the dot has been kept, such as the hole burned in the morning. The straw instrument is ready to play, with the same mouth shape as other wind instruments. If the eight holes are airtight, drums can be played, and the holes above are not allowed to leak. You can play with the whole hedgehog shadow with your straw. It will be easy if you start. Just try it. In order to make the pipe body durable, one or two broken straws can be wrapped outside to increase the strength, and the width of the opening can not be wrapped to avoid scalding the hole. Remember, leave half a centimeter to insert the primer, and cut off the extra half a centimeter below. When the straw is finished, learn to play and then make the hard straw below. This straw instrument has a wider range and can play two octaves. We'll discuss it then. Using straws as musical instruments, I once gave students music manual lessons, which will make children like music lessons, exercise their hands-on ability and listening ability, and lay a good foundation for learning other wind instruments. You can also do simple manual work with straws!
