Children's Play Culture in Old Korea

This is called 'Ggwari' in Korean.
Usually, it is characterized by a large number of clusters forming on the ground cherry(Mouth Clacker, Bladder cherry) tree, but here is only one fruit of ggwari.
In the countryside, it is also called Ddengal.

Once upon a time, children in Korea, they dug out the insides of ggwari and blew a lot of ggwari in the old days.

When the wind went through the hole with this twist in their mouth, he blew it for fun, making a sound when children pressed it with their teeth.

However, with the production of rubber ggawari, this fun play is over.
