“Everyone gets sick sometimes, and it is pretty hard to avoid every germ all the time, but you can prevent the spread of germs by carefully washing your hands. Germs are everywhere and when we touch things, we get germs on our hands. Then we touch other things and those germs spread from object to object and person to person.
In this video from DragonflyTV, Jordan and Sydney do a science experiment to see how germs spread. They want to know which leads to the spread of more germs: covering your nose with your hands or with your elbow when you sneeze. Since germs are too small to easily track, Jordan and Sydney use a powder called Glo Germ, which can only be seen under an ultraviolet light, to simulate the spread of germs. Which technique do you think spreads more germs? Watch the video and find out!”
