Walter, a 16-year-old, purchased an educational chemistry set manufactured by Chemco. Walter invited his friend and classmate, Peter, to assist him in a chemistry project. Referring to a library chemistry book on explosives and finding that the chemistry set contained all of the necessary chemicals, Walter and Peter agreed to make a bomb. During the course of the project, Walter carelessly knocked a lighted Bunsen burner into a bowl of chemicals from the chemistry set. The chemicals burst into flames, injuring Peter. In a suit by Peter against Chemco, based on strict liability, Peter will 
prevail, if the chemistry set did not contain a warning that its contents could be combined to form dangerous explosives.  prevail, because manufacturers of chemistry sets are engaged in an abnormally dangerous activity.  not prevail, because Walter's negligence was the cause in fact of Peter's injury.  not prevail, if the chemistry set was as safe as possible, consistent with its educational purposes, and its benefits exceeded its risks.
