Autumn  and winter is the time of flu and infection. This is also the time when you should especially keep your hands clean, because of bacteria and microbes  they get it from their hands  myself  with food to our body. 

At a school in Idaho, America, a science teacher made a decision  conduct an experiment with your students to show them how important it is to wash their hands  stop the virus from attacking you. 

Results and awareness  spreads  with a stunning post that has become very popular  .

Jaralee Annice Metcalf shared photos of a research project she carried out with her class for a series of  of the photos she wrote:

​

"We took fresh bread and touched it:

• One piece was left  untouched.

• We touched one  with unwashed hands ..

• One  - with hands after "washing"  hand sanitizer.

• One - with washed hands  warm soapy water.

• One  we decided to rub all of them  laptops in our  class ".

Metcalf noticed that the school usually sanitizes laptops, but did not do so in this experiment. 

We had to wait for the results since  three to four weeks due to the preservatives contained in the bread, which extend the shelf life.  The bread was placed in sealed Ziploc bags in the freezer.

"If the bread was exposed to air and moisture, the experiment could go faster," reports Metcalf to Parents.com. "On slices  bread that was very much  when exposed to various germs, it grew faster  mold. And those touched with clean, washed hands  with soap and water were not exposed to germs,  accelerating the growth of mold ”.

Result?! See for yourself in the pictures.
