My crazy idea is to produce the Tinned Bread.
People have already tried to tin everything.. tinned fruits, vegetables, meat, fish, soap, salads, nuts, peanuts, and etc. .. but.. I have never heard about tinned bread.
I think it will be very comfortable to have tinned bread. I guess many people will desire to buy it.
E.g. you are going to picnic, climbing mountains, going to a forest for a long time or something else. It would be cool if you open a tin and take not a dry old stick but fresh bread. You will eat it with the great pleasure.
