What humble object would you like to praise?

Toilet paper I know, but seriously

Cotton candy

LED lights. I remember when I was nine or ten years old I read in a school social studies newspaper that scientists were trying to invent lights which give off no heat. I had a lamp without a shade fall against my arm once. It made contact for only a second, but the resulting blister was huge and painful. I didn’t think anyone could take the heat out of lights, but I loved the idea.

Duct tape, best babysitting tool, ever! Also great for car repairs, getting that gutter to stay up against the roof edge, and prevents kids from falling out of their beds.

Rubber bands

Disposable diapers

Washers and dryers. They are such a benefit for hygiene and cleanliness.
Also I always appreciate my coffee being ready as soon as I get up.

Since I was born, I remember when the first Bic Stics were released. Ball point pens were not universally used…fountain pens were still prevalent. I’d like to give a shout out to cheap ball point pens. Solid design that hasn’t had to change much over the decades, used by millions of people every day, and so very humble!

Rope.
A few feet of it.
Very versatile thingy.

I’m a little concerned about @Patty_Melt using duct tape to baby sit. :-)
Dental floss is the best invention ever. And scissors.

A toffee hammer.

Concrete. It makes travel so much easier.

The bonesaw. Makes covertly getting rid of certain things much easier.

The hamburger.

Shoes and orthotics that enable comfortable walking

Cast iron cookware, especially the items crafted a hundred or more years ago.

The can opener.
The potato peeler.
The self contained firearm cartridge.
The strike anywhere match.

The coffee maker and coffee cup. My day would be much grimmer without them.

I very rarely hear my TV say or display, anything boastful or arrogant.

Whenever it does blather about being a stable genius or doing everything perfectly, I’m only a few seconds away from the mute button, on my much more secure remote. ;-)

Clothing. All cultures have clothing, and it was likely invented numerous times, but the practice of weaving threads to form cloth seems like an inspired idea to me

The doorknob is a fairly elegant thing that is constantly used and life without them would be a nightmare.

Maybe not so simple, but certainly elegant and has been around since the mid-19th century: the sewing machine. I use mine a lot and I am grateful for it’s existence.

Nail clipper.

@LostInParadise, I nearly included woven fabrics myself.

Working my current novel about contemporary people isolated in a primitive setting, I have been musing over simple objects or projects which must have at some time been a huge leap forward.

Toaster oven. I use one almost every day.

Flatware. I never could get the hang of chopsticks, I like being able to cut my food into small pieces. If I can only choose one utensil from the set I pick the knife.

Lightbulb.
