I wasn't buzzing any particular tune, but you could do simple songs. Maybe play these at a birthday party?
The first step is to gather your materials.
2 Popsicle sticks
2 rubber bands
1 strip of paper
You'll also need scissors to cut the paper.
If you want to be decorative, you can cover the sticks in duct tape like me.
Next, cut a strip of paper the approximate size of the Popsicle stick. Then cut two pieces of toothpick the width of the stick.
Lay the strip of paper over the Popsicle stick and a toothpick piece on top of it.
Wrap a rubber band on the side with the toothpick. Then put the second toothpick piece on the opposite side of the paper.
Secure the final rubber band around the open end, and put your mouth lightly on the Popsicle sticks. Blow fast, and you'll get a loud buzz that you can change the pitch of depending on how much you squeeze your lips on the Popsicle sticks. Enjoy!
