They are suing cuz they say the teacher didnt warn them of the dangers of electricuting himself. HELLLLLLOOOOOOO bozo you are in high school. You need someone to explain to you that attaching wires to your nipples and plugging it is is dangerous then you are a moron and an idiot and your parents are most definitely closely related. If these were little kids then they would need to be closely supervised but high school students which are most likely 16-18yrs definitely know better. You live in a society of greedy lawyers who like to sue and are taking advantage of this situation.
