Straw kazoo amplifier! For when you really want people to hear your straw kazoo. The opening keeps the straw slightly squished which creates the kazoo sound. Just cut a taper into the straw as shown in the picture.
Design uses a Chick-fil-a straw but I assume that it will work with most any fast food straw.
No supports needed :)
The author marked this model as their own original creation.
