Thinkwell Chemistry lab #4's last question...

If you have ever been to a public pool, you know that you are required to exit the pool when there is lightning in the sky. But consider your results from part (a) above and what you learned in this lab, paying particular attention to the very first demonstration that the instructor shows you regarding the light bulb. Does this protocol make sense in light of the data from this demonstration, or is it contradictory? Why or why not? We are talking about water, here, right? Is there anything else going on in this case, chemically speaking, that would change the way we look at this situation?
