It is an eye horn.
It is like a shoe horn but it is for putting your eyeball back in the socket when it accidentially pops out.
I'm sure those of you who have had to do this on your own, without my invention have had trouble with getting your eyelid stuck behind the eyeball when you pop it back in. Sort of like when you step into your shoe and the upper back of the heel gets stuck under your foot when you don't use a shoe horn.
I was thinking blue would be a good color.
Well?

For those EVPers who believe in the non-acoustic model of EVP, e.g., "the spirit impresses the information directly on the tape or recording device", my question is why do you use microphones at all then?

For those EVPers who believe in the acoustic model of EVP, e.g., a spirit speaks audible words despite not having vocal chords, how is it possible that the recording device can pick up the sound while the human ear cannot? This especially goes out to those who claim to have Class A EVPs where the supposed ghost voice has a volume nearly as loud as those of the ghost hunters making the recording.
