What do familiar objects look like once upon a time?

There is an obvious rule that everything changes over time. Every day new, our world has new technologies, and familiar objects today will have new functions or complete improvements.

Therefore, it is easy to understand when we cannot expect what the things of today look like when they are born.

Here are interesting examples of how progress and civilization have completely changed our lives, through the close objects below.

1. Television

Instead of ultra-thin ultra-thin televisions, the old TV was just a bulky wooden box.

Television - television equipment - was mass-produced for the first time in Germany in 1934. At that time, they were actually big wooden boxes with a tiny screen that showed images of noise. .

However, a television at that time cost $ 445, equivalent to nearly $ 7,000 compared to today (about VND 159 million).

If you look at ultra-thin plasma TVs with ultra-wide screens sold in electronics stores, it's clear that these things are too unbelievable.

2. Sunglasses

Sunglasses turned out to be initially not a shade.

The first sunglasses were used to prevent the eyes from being glared by snow, not the sun.

Residents of Far North (Russia) used wood, bone, and other non-penetrating materials to create glasses with two openings in their eyes, enabling them to protect their eyesight first. The light that snow and ice reflects is too harsh.

Today, sunglasses are in addition to protecting the eyes from the sun but it is also a fashion accessory with a variety of types, even different from the original use.

3. Digital camera

Camera was quite heavy in the past and could not be moved.

To capture a memorable moment with high definition, we can now easily press a button on the phone or use a compact camera.

However, in 1975, the first digital cameras weighed 3.6kg, attached to a cassette player. Surprisingly, it needs up to 16 new batteries that can be operated.

4. Toilet paper

Paper was present in 589 AD but it was not until 1880 that the modern toilet paper cores were born.

The paper was first used for personal hygiene purposes in 589 AD in China. But it was not until 1857 that toilet paper was produced for commercial purposes, in the form of square pieces packed in packs.

The toilet paper roll, which is similar to what we have today, first appeared in the 1880s in the United Kingdom.

5. Washing machine

The washing machine of the day before must be operated by human or animal pulling force.

The first washing machines were patented in 1851. They are very different from modern washing machines and must be operated with a crank. There are other early versions that even use the tensile strength of 10 mules to wash 10-15 clothes at once.

Now it is convenient that we only need to use electricity to run a washing machine, not a hay.

6. All

The socks are not only different in shape but they have been a symbol of purity and wealth.

Legs first appeared in Egypt from the 3rd century AD, when they were made from animal skins tied around the ankles. The concave part between the big toe and the index finger is explained by the ancient Egyptians often wearing socks with flip-flops.

7. Drilling machine

Early drilling tools were very manual and not very effective.

If today, just pressing a button on the drill is easy to create a hole on the surface of construction materials.

However long before electric drill was invented in the mid-19th century, hand drills were used in ancient Rome. Clearly, it took a lot of time and effort to be able to use the drill and produce the desired results.

8. Tampons

The unexpected fact is that tampon tampons have been around since ancient times.

It turns out that women have used tampon - sanitary pads since ancient times, but the first versions are really different from hygienic products that we can find in grocery stores.

In many different cultures, tampons can be made from papyrus, wool, paper or even fern leaves; they are assembled by tape fabric.

Meanwhile, modern cotton cloth tampon was invented in the 1930s.

9. Life jacket

Life vests were heavy at first and even hindered users' movements.

Life jackets are one of the most widely used personal rescue devices today. But not always. In the early 20th century, life jackets were not so popular because they were supposed to interfere with the wearer's movements.

10. Roller skates

I don't understand how big the shoe is, how does it slip?

Evidence of roller skates for the first time has been around since 1743, but the first versions are almost unlike popular designs today (in fact, they are almost impossible to use because they are too big bulky). The later designs are not improved as well.

It wasn't until the 1970s that skates similar to the ones we used today were invented - capital to help hockey athletes easily slip on ice.

11. Calculator

The computer in the past depends more on users than the accuracy of the machine itself.

The first computers, also known as accounting machines, can only calculate four operations: addition, subtraction, multiplication and division. Besides, the accuracy of the computer at that time did not depend on the machine itself but depends on the computing power of its users.

In contrast, computers today are much simpler, more functional, and most importantly, much more compact.

12. Hard drive

The hard drive is so big and heavy that it only contains 5MB of information.

60 years ago, the first hard drive was released to the public. They weigh up to 6.35kg and only 5MB of storage. Today, even simple mobile phones weigh only a few hundred grams, and can hold 10 times the amount of information the first hard drive.
