What is a Paper Banger?
The paper banger is a "bang producer" made of paper.
It is easy to fold from a sheet of paper.
The paper banger is well known. - Knalltüte (bang
bag) is the German name.

Attempt of Explanation:
The air is pressed inside during moving the paper banger
downwards and the air suddenly is free when the inner layer is coming out.
It is a small explosion.

If you use stiff or thick paper, you don't succeed in
moving the inner flap outwards.
For instance the paper used for ink jet printers is unsuitable.
I must admit that the bang
is not very loud. In spite of that the paper banger is popular.
>You can fold the banger easily and quickly. Children
are proud if they know how to make it.
>There is a surprise that such a folding can create a
bang.
>It's amazing that only one layer is coming out of the
banger from inside.
>You can change the size and the thickness of the paper
and find out what is best.
There is another way of creating
a bang: In Germany children [or adults ;-)] like to use a bread roll paper
bag for banging.. They blow into the empty bag until it is filled with
air, close the opening and hit the closed bag on the table. The bag bursts
with a loud bang which is hard to ignore, - nice, too.

Why simple, if it can be difficult?
You could ask this, if you are going to know the "bang
paper". Peter Schuhmacher from Lengnau (Switzerland) sent me the instructions.
You fold twice and the paper banger is finished.
