What are the wonderful human inventions with wide brain holes?

Grandpa Deng said that science and technology are the primary productive forces. But we must admit that many inventions were invented by lazy people.

Because I am too lazy to climb the stairs, there is an elevator;

Because I am too lazy to walk, I have a bike, a train and a plane.

Because I am too lazy to calculate, I have an abacus and a calculator;

Because of laziness ... there are too many such cases.

Today we are going to talk about some wonderful inventions in the world. Let us witness that invention depends not only on laziness, but also on some wonderful ideas.

Let's witness together.

1, jet flying backpack.

It was in 1969 that a young man in the United States invented a flying backpack with jet, but the recoil was not enough. He flew in the air for less than 20 seconds and then fell down. But it laid a good foundation for later jet planes.

2. A deadly smoking rack

Such an invention is really fatal. I wonder if a round of smoking will ascend to heaven.

3. Local mower

I heard that this magical local mower has built-in air conditioner and telephone. Don't worry about the heat, you can make a phone call while mowing the grass.

4. Light the car tires

196 1 year, some young designers painted luminous materials on four tires of cars. At that time, driving a car like this must be the brightest kid on this street.

5. pipe for two

I haven't understood, for what purpose was the inventor of this double tube invented, was it specially invented for gay friends?

6, sun oil vending machine

Americans advocate sunbathing, so someone invented this kind of oiler, which can make people's skin turn bronzed in a short time.

7. Nuclear bomb shelter

I wonder if this kind of shelter is reliable. It is said that it can accommodate 8- 12 people, but I wonder if there is life underground in the shelter.

8, vibrating breast bra

You have to be energetic all the time to get more and more stiff. How to raise it? You need to give her a massage, so someone with a big brain hole invented this vibrating breast enhancement bra, but I just don't know if the effect is good.

9. Transparent boats and boats

Rowing this boat can see small fish in the water, which is very thoughtful.

10, artificial hand with automatic tip collection

It's normal to accept tips in America, but some waiters just care about face. What should I do with this? Not for sale? A prosthetic hand that automatically collects tips is much more convenient.

1 1, rocket bike

This is a German engineer who pursues speed. In order to make the bike run at the fastest speed, a rocket launcher was added at the back of the bike. After the bicycle was ignited, it fell apart directly because of its high speed.

12, automatic noodle rolling machine

Italians like to eat noodles, but it is inconvenient to use a fork every time, so they invented this small device for automatically rolling spaghetti.

13, moisture-proof cover

1970, in order to avoid washing off makeup, western women invented this anti-shampoo cover.

14, baby hanging window

In the past, western babies used to get a hanging basket outside the window and shut their children out. Think about it. At that time, West Renye Fang was brave and not afraid of failure.

15, catch it

This is China's weapon. It looks like a hand, but what is it? Nails? But very sharp. I wonder if this weapon is powerful on the battlefield.

16, human radar

In Italy, there was no radar at that time, and air defense only relied on people to observe with their eyes and listen to the sound of aircraft engines with their ears. But human hearing is limited after all, so someone invented this thing.

17, balloon bomb

During World War II, Japan blew up the United States and Canada with balloons containing 9300 bombs. But only 357 hit the target, and two others drifted back to Japan to blow up their own people.
