Removing gingko tree's berries

Maybe it sounds wierd.
In korea, Eating Gingko tree's berries is not wierd thing.

My colleague gave me handful Ginkgo berries a few weeks ago.
also she gave me a way how can I remove gingko berries easily.

The way is like this.
1.prepare empty milk box(paper one, and it should have dried.)
2.put gingko berries into the milk pack and rock the entrance
3.Turn on Microwave for 1~2 minutes
4.Finish (Whatch out! becuase maybe it will bounce)


I followed this process.
but microwave didn't work well, I'm not sure.
so I used bat. and removed gingko berries's hard skin.

This is the scene what I did.
