Baby strollers became popular in the mid-19th century but kept the same structure for several decades. Somewhere along the 20th century, it became more of what we know today. The stroller was first designed with a metal frame and a not-so-comfortable inner piece, making the baby regret the moment it chose to come out, knowing that the womb was far more pleasant.
Today’s strollers are definitely smaller, made from friendly material, and provide our babies a great spot for napping, as more and more parents find the stroller the easiest place to put the little ones to sleep.
We put little thought into something we set our eyes on almost every day, not realizing that the traffic lights we use are probably one of the most important inventions ever. Controlling traffic and saving lives, they haven't been always so driver-friendly.
Starting off with the support of semaphore hands, the traffic lights in the old days were manually operated. It took a few decades before they became 100% computerized as they are today. So next time you're in your car, waiting for that green light, remember Garrett Morgan who invented these lights, making the roads safer for us all.
Sewing machines are not a device used by many these days. Going back a few decades, everyone, and we mean everyone, had one of these machines, as they were essential like an iron or a cooker. If your kid fell, scraped their knee, and ripped their pants, how do you think a patch was stitched on?
From a stable, attached-to-table machine, to a compact portable, lightweight-friendly device, the sewing machines have no need for pedals at the base and definitely come in handy when something needs stitching (and no, this won't work on stitching wounds).
Over the years, phones have gone through many changes in design and size but the biggest change of them all is when they became mobile. Back in the day, telephones were used for communication via speech, and today, the communication platforms are unlimited, starting with verbal, text written, video calls, and more.
The phone today is one of the most important devices for humanity, making it almost impossible to lead a normal life without it. Basically, if we held a survey asking people what would they choose first, an arm or a phone, we all know the answer to that.
One hundred years ago, the car key was simply a regular key, usually with the car's manufacturer's symbol engraved into it. The keys were simple keys used for opening and locking the car door. These days, opening the car door is not their main purpose.
They open the trunk of the car, control the music pannel, operate the rooftop, turn on the AC in your home, and switch on the massage button attached to the car's seats. Who needs a vehicle these days? All we need to make our life better is a set of keys.
