An experiment.

Helaman's teacher did an experiment with bread.  She took three slices from cheap bread.  The first one she used gloves and put a slice of bread into a ziplock bag and sealed it.  The second slice of bread she took the bread and sealed it into a ziplock bag, but this time she used ungloved hands.  The third slice she passed the slice of bread around the classroom allowing all the children to touch the bread, just after recess.

The results were the first slice still has no mold.  The second slice became a little moldy, but the third slice became really moldy.  The first signs of mold started between 12-14 days after bagging.

The teacher showed the parents this on parent night.  Of course our first response was gross look at all those kids germs.  But then I started thinking, wait a second, this is fake bread.  Fake bread has so many mold inhibitors what would happen to real bread.  So I took this experiment to the next level.

I made an oatmeal, wheat, honey bread, then I took organic seeded franz bread, then I had some hotdog buns as cheap white bread.  I decided that I wanted to have a couple of different criteria.

The first slice of the three different breads I used gloves and put the slices into a ziplock bag.

The second slices of each bread I dropped on the floor and let them sit on the floor for 5 minutes and then I picked then up with gloved hands and sealed them in ziplock bags.

The third slices of each of the different breads the kids and I handled, but only after we got our hands filthy.  For example the kids went out and caught frogs, sneezed into their hand, wiped their faces, etc  But before we touched our bread we slathered our hands with anti-bacterial gel.

We got our first results today.  We looked at the slices on the fridge and noticed that mold had started to grow on the real bread, only after 8 days. The white bread still nothing.

Still no mold

Results:
~The floor is not that bad, hands are worse.
~The hand sanitizer does nothing if your hands are gross.
~White bread still has no mold.  Just like plastic

So I guess the saying about the "five second rule" when food falls on the floor, that the food is still good if you pick it up before 5 seconds, is true. I had a roommate at Snow College that would scream when her food fell on the floor. Her reasoning was that if she screamed..no germs or dirt would stick to her fallen food and she would pick it up and finish eating it.

Interesting results to your fun experiment. A future science fair project!
Love you all. Hugs, Aunt Valerie
