Well I had planned to go for a walk on a hot day, so the plan was to bring a bottle of cold water with me.
Easy breezy. I took an empty 710ml bottle of Pepsi and filled it with 1/4 water and put it in the freezer. After it was frozen, I then filled the rest with cold water. But due to cooling the bottle in the freezer, the mid section changed into a triangular shape due to the air having cooled and had caused a partial vacuum.
Anyhow, this triangular shape made it so easy to carry. It fit the shape of the hand so perfectly, and it looked so cool.
So I thought that maybe I could make some money by suggesting this bottle shape to the Pepsi company. They said that ideas were welcome, but any benefits to the company would be in the hands of the company only, meaning any ideas presented to the company immediately become the possession of the company itself. Bloody selfish bastards.
I know what you are saying. The triangular shape made it so that it required about one tenth the effort to hold the bottle, and like I said, it had a cool look as well. It reminds me of the Mcdonald brothers. They started the Mcdonald burgers but ended up with darn near nothing in the long run.
Watch the the movie called , The Founder. it is available on Netflix.
