Welcome! Watched the whole thing and learned some things. I liked the chlorine tablet idea...dosage is another issue.

I think the whole talk would have been alot neater, if for example when you were talking about the chlorine..you actually take out the razor, and shave off the appropriate amount as a demo. Kind of like you did with giving the kid the space blanket and having him demo the position to get in.

Good job and again welcome.
