Hello everybody! How are you? I'm reading a book
about inventions. Inventions are great.
In fact, most of the things you use everyday are inventions.
Like a toothbrush or the vacuum cleaner.
Shall we do a quiz?
I am going to show you some inventions and you have to guess
who invented what. Are you ready?
Welcome to our quiz. Who invented what?
Today we have four inventors.
Two men and two women.
They are Johannes Gutenberg,
Thomas Alva Edison, Anne Makosinski
and Florence Lawrence.
I am going to show you some inventions and you have to guess
who invented what.
This is our first invention.
The turn and brake signals on a car.
Shall I give you some clues?
That's like a jula. So...
Who do you think invented the turn and brake signals?
Was it...
Yes, it was Florence Lawrence.
She was a Hollywood actress and very famous.
She loved cars and thought about a system, so all the drivers
can know what direction you are going.
Our second invention is the printing press.
Do you know who invented it? Was it...?
Yes, that's right.
It was Johannes Gutenberg.
Before the printing press it took many years
to make a book because they had to be copied out by hand.
With the invention of the printing press
Johannes Gutenberg made copies of several books
very quickly.
Our third invention is the hollow flashlight.
A special torch that doesn't need batteries.
Who do you think invented it? Was it...?
That's correct. It was Ann Makosinski.
When Ann was seventeen and a student,
she had a friend which had no electric lights
in her house so she couldn't study or read at night.
So Ann invented the hollow flashlight, a special torch
that doesn't need batteries. It works with the heat
from our bodies. Isn't it amazing?
Ann has won many prizes for her inventions. Very clever!
¡Guau!
And our last invention is also related to light.
It's the lightbulb.
Who do you think invented it?
Was it...?
Of course. It was Thomas Edison.
He is famous for trying again and again, hundreds of times
until he was successful.
And that's the end of our quiz for today.
Thanks for watching.
Today we have seen...
Florence Lawrence invented the turn signal.
Johannes Gutenberg invented the printing press
and Makosinski invented the hollow flashlight
and Thomas Edison invented the lightbulb.
And we've seen that inventors can be students, just like you!
Do you have an idea for invention?
See you next time, everybody. Goodbye!
