This invention seems practical, because you can heat the bread soon.The bread is on his point and also you don´t stain anything.
Thanks to the toaster you can take a quick, healthy breakfast.

The toaster´s function is release off heat to heat the bread, electromagnets driving through a resistor.
The toaster was maked for the first time in U.S.A in 1909.

In my opinion isn´t an invention that call a lot of attention, but everyone has one in their kitchens.

  There have been many amazing inventions in the last years old. In my opinion the best invention is the Twitter.

Thanks to the Twitter you can write with the people the of your city or other countries almost instantly.
In addiction you can go up photos, videos and can do twetcam( TC ), retweet ( RT ), follow and you follow, chose the favourite tweet and Trending Topic( TT )

An oven of microwave, it is a domestic appliance used in the kitchen to warm food that it works by means of the generation of electromagnetic waves in the frequency of the microwaves, of 2,5 GHz.
