Judge: would it would work because there is a negative charge and a positive so that should mean that it could work as a battery.
Jury: So it will work because there is a positive charge and a negative charge.
Lawyer: No it would not work because one negative and one positive will not make it work. It would not do anything it needs something to get it moving.
Judge: So what is the other thing we would need?
Lawyer: The other thing we would need is copper Sulfate because that is another positive charge. That will make it work because then the two strips will have something to work with.
Jury: The Lawyer is right. It would not work with only the two strips you would need the copper Sulfate to help it work.
