But is it? What about those hand sanitizers many people carry around. Do they work better? Or at all?
Many Valley kids are doing it; playing games like basketball and cheering each other on from the sidelines. You better believe that plenty of their hands touched the ball too.
In the test, 16 nine and ten-year-olds tried eight products, half name brand hand sanitizers and half generics. Four others tried soap and/or just water.
Here's one student's theory: "If you wash your hands with water you get a couple off your hands, but if you use soap and water you'll probably get most of the germs off your hands."
The test worked like this: Each child touched their finger tips to a petri dish before treatment. Then a squirt of hand sanitizer and they touched the petri dish again. Most hand sanitizers contain some kind of alcohol compound, either ethyl or isopropyl.
Then the petri dishes were sent to Burt Anderson, a Professor of Molecular Medicine at the
The results were pretty clear. In the petri dish from one student's test, Burt Anderson says there were 90 to 100 colonies of bacteria before she used an alcohol-free foaming hand sanitizer.
“In this case it was a hand sanitizer using the compound called benzalkonium chloride. You can see a drastic and dramatic reduction to no colonies at all,”
