Handmade paper microphone

1, prepare a prototype plastic ball. As long as it is round, table tennis can also replace it.

2, cut off the head of the mineral water bottle, you can put the ball you prepared, so be sure to measure the diameter of the ball.

3. Then press the ball into the head of mineral water. If you can't just press it in, you'd better fix it with glue first.

4. Then roll it into a tube shape with a diameter similar to the bottle mouth of the mineral water bottle.

5. Then connect the paper tube to the mineral water inlet, as shown in the figure below, and then fix the paper tube with a rubber band.

6. Then wrap the whole microphone with tape and decorate it with some stickers, as shown in the figure below.
