"Dispense" is one of those funny words that can have its meaning changed by associating just one more word with it, e.g., "dispense" and "dispense with" mean two different things. That doesn't have anything to do with finding the cache, but I thought I should say something here. (Along those lines, did you know that "weird" is a weird word? It doesn't obey the rule for whether "e" follows "i" or vice versa.)
I can imagine muggles making this one a little difficult at certain times of the day. You might want to do this one at night.
For people who like challenges, I apologize if I'm reducing the already minuscule challenge to this cache, but although I hope people enjoy finding my caches, it would be a really bad thing if that enjoyment turned into an electrifying experience. When "searching" for/retrieving the cache, there is absolutely NO need to stick any body parts, or things attached to any body part, into any opening in any light or other electrical fixture. Do not touch any wires protruding from any such structure. (I'd like to say that such warnings should apply to any geocaching situation but I've encountered some hides that weren't thought out very well. This isn't one of those.)
