Now that we know how to spot germs on our hands we can convert it into a full fledged science experiment. The objective is going to be to find out which part of the hand the germs cling to the longest and how the lenght of time spent washing hands affects them.

Besides the Glo Germ Gel and the Ultra Violet Light pen you are going to need a few friends to help you carry out this experiment. First record the area of germ concentration on the individual’s hands before washing hands with soap. Then record the reduced germ concentration areas. Then make them wash their hands for another two minutes thoroughly and see how many germs are left.

You will need to repeat the process with each friend who takes part in the experiment to collect enough data to examine. Now corelate the data to find which parts of the hand are the most difficult to rid of germs. You can divide the hand into sections like palms, fingers, between the fingers, around the fingernails and the back of the hand.

Note down all your observations and formulate the conclusion based on these observations. You can make two lists for after the first hand washing and the second hand washing. It is an easy and interesting science project to do.
