When you rub against the slide, either electrons
get rubbed off of it or off of you, and when the
charge is enough, it sparks to equalize the
charge. This spark has a current, of course, and
therein is the shock.With the information that you
have given me, there is no way to tell for sure
whether the electrons come from you or from the
slide. If you got some item that you knew had a
negative or positive charge, you could drop it on
the slide to see if the slide attracted or
repelled it - repulsion means same charge,
attraction means opposite charge. I don't know
offhand where you could get such an item, but you
might be able to read up about one.
