It's bedtime. Mom is cleaning instead of sleeping. A sister and brother decide they are going to surprise their MOM and get rid of all the germs in the house. Their plan is to lock all the windows and doors and spray the whole house with germ spray. That's genius! At least they think so. Now they can wake up to a germ-free house and Mom gets a break. But their Mom tells them the things they do every day is what causes germs and what gives it to others. Germs spread from kid to kid or surface to kid because kids are touchy feely. As they learn about the spread of germs they discover its' not as simple as one big spray.
