How many WILL YOU get right?

I missed the match holder, never seen anything like it. The out door sound for the film i guessed, once again never seen it. The water sprinkler I knew because I have been shown how to use the old irons that you had to heat, ( people use to spit on the irons to see if they were hot) also people sometimes had a little bowl of water to dip there fingers into and then splash the water on the cloth.
I once dug my old slide rule out and tried to remember how it all worked, but sadly could only remember about half.
So how many know how to use a slide rule
