I'm a big fan of this umbrella with a window from 1935

what makes something chindogu?

  1. Chindogu must exist

Chindogu have to be made. If you design the invention on paper and don’t make it, it doesn’t qualify. It’s a piece of paper with a bad invention on it. Bring the invention into the physical world so humankind can experience how truly almost useless it is.

:rofl:

eta:
  1. Chindogu are without prejudice

Chindogu view all human beings as equal. Therefore, they can’t favor a race, religion, age group, gender, or class

those are some good rules!
