What 's made the light bulb?

It consists of a glass globe is hollow inside and has a filament by passing electricity, causing light.

The advantages using a light bulb are thar bulbs:

- Currently the bulbs have evolved greatly, for example, are now low energy and pollute little.

- Give Light to the streets, and that makes them less dangerous.

Now we can do more things within schools, supermarkets, our homes, when natural light doesn’t illuminate the things we are doing too much.

On the contrays :

For example when one bulb burns out, the person instead of recycling strip away and that pollutes much.

The light bulbs causes us spend too much money because electricity is very expensive.

Besides isn’t very good to be all day locked up somewhere in this light, because you have to give the sunlight.

In conclusion, I think that this invention has changed the world.
