"My experiment showed a simple air test of the bathroom, and a test of air being blown onto a petri dish with varying amounts of air blown.
Tim carried out his investigation by first placing a petri dish in a public toilet area, capturing five bacterial colonies from the ambient air.
For a more focused test, he placed another petri dish under a hand dryer which, after just one activation, revealed eight bacterial colonies.
While the experiment shows that there are bacteria in the air and that a small amount will blow onto your hands, I don't believe this is from the hand dryer.
Tim Call highlighted the astonishing number of germs lurking in public hand dryers, which could be a nightmare scenario for anyone with germaphobic tendencies.
