It’s difficult to pick one invention to stand out as the greatest of all time. There are so many manmade wonders that enrich our lives every day and make us question how we ever lived without them. For example: the wheel, the flushable toilet, beer, Velcro, eyeglasses, the atomic bomb and plastic storage containers.

The printing press and the Internet are certainly great inventions, but they make it just as easy to spread lies as the truth, so I can’t rate them high on my list. They certainly don’t rate above plastic storage containers, which have brought society nothing but positive outcomes.

It wasn’t long ago when people had to go to grocery stores and beg for flimsy cardboard boxes to package their belongings for a move. It was difficult to get a good grip on those boxes and I never knew when the bottom would fall out and all my Smurf glasses would smash at my feet. But plastic storage containers are lightweight, sturdy and stackable, with easy-to-grip handles on the sides. They are one of the greatest inventions of all time.

There are maybe a dozen inventions I would list ahead of plastic storage containers, and all of them are forms of contraception. I’d even put the withdrawal method near the top of the list. I know it’s not very effective, but it was a good start.
