Styrofoam was invented in 1944.
Plastic lined paper cups were invented in 1950.
High-density plastic (now used for milk jugs among many other things) was invented in 1957.
Bic released the first disposable pen in 1958.
Disposable razors came onto the scene in 1960.
In 1964, Coca-Cola still came in reusable glass bottles.
Bread started being sold in plastic bags in 1969.
The great thing about these facts is that we can still see how our parents and grandparents shaved, wrote, ate, and drank without the aid of single use containers. I am fortunate enough to have access to returnable + reusable glass milk containers...which used to be the norm. Local bottlers used to exist in order to clean and refill returned glass soda bottles as well.
When I was growing up, we used metal ice cube trays. I have to admit that I was a bit envious of the unbroken cubes my friends' were able to produce at their homes... but now I'm envious of my mom's unbroken ice cube trays. :)
I was able to find this one online, and I believed the reviews to reveal a case for buying the Onyx brand tray that is 18/8 stainless steel. The imitation seems flimsy and prone to break.
Just a little reminder that sometimes it can help to take a look at the past to create a better future. :)
