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.
Comments top
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.
