How to make a simple handmade musical instrument?

1, we first prepare the materials: tape, a cone paper tube, pencil, plastic straw, scissors.

2, then we start by flattening one end of the straw with our hands, several times, as shown in the picture below.

3, then use scissors to cut the flattened straw into a pointed end, divided into two flaps, as shown in the picture below.

4, then we use a pencil to draw a line along the top of the cone, around, as shown in the picture below.

5, then follow the previous step, use scissors to cut along the drawn line, as shown in the picture.

6, cut the tip of the straw, separated on both sides of the cone, and then taped, so a handmade horn is ready.
