I bought a Zoom 505 2 multi effects processor. It has two such effects on it . One is an octave higher and one is half an octave. I can look up the actual name if you want. Just private message me or something
There are multi-octave effects pedals out there... but he also uses a lot of pinch harmonics in Third Eye and actually, most Tool songs. If this is what you're thinking of, I'll post a follow up with a larger explanation.

on gibson les pauls, among others (i.e. not my fender), the strings pass through the bridge and go into the body, you can pick the strings there, and it should make that sound
he uses this on other songs like Eulogy and maybe Forty Six &2, im not sure
ya, its a whammy.
theres a pantera song where the guitarist pulls it up reeeal high with the tremolo and uses the whammy up as well to make this evil totally high pitchrd scream noise
I have an Ibanez (however not a Gibson...) that's strings go all the way through, and I've messed with picking, and i've gotten some of the pinch-effects,
But nothing like that.
Listen to it around 11:50 on the Salival Third Eye.

That "shrouding all the ground around me part" (and that part later on) is not pinch harmonics, it's just Adam plucking between the bridge and the tailpiece of his Les Paul.
He's also doing that in the beginning of Eulogy.
In almost every other Tool song he's using pinched harmonics, which is a tricky picking technique. You'll probably find an explaination for that somewhere on the web.
And the Whammy that was mentioned earlier is used by Justin only. Adam has never used a Whammy in any Tool songs. He sticks to delay, flanger and wah most of the time.
