I read this somewhere and don't understand it.  Can someone break it down for me.

This Part I understand -
"Imagine you have an Arbor Elf on the battlefield with Illusionist's Bracers on it and a Breeding Pool in play. You cast Galvanic Alchemist and pair it with your Arbor Elf.

What next? Okay, this is where it gets complicated. You tap your Breeding Pool for a blue mana, then tap Arbor Elf to untap the pool. This gives you a second Arbor Elf trigger, which also targets the Pool. The Breeding Pool untaps from the first Arbor Elf ability, then be sure to tap the Pool again before the second ability resolves. Once the original Arbor Elf ability resolves, tap the pool for a third mana.

Now what?

This is the part I don't get -
Now you activate Arbor Elf's Galvanic Alchemist–granted ability. This puts a pair of untap triggers on the stack. The first one resolves. Then tap Arbor Elf to get two triggers, and therefore two mana. Then let the second untap ability resolve. Tap the elf once more for two abilities and two more mana.

The end result of all this madness? You're right back where you started—except now you have one extra blue or green mana in your mana pool. Repeat as many times as desired."

I don't get where the pair of untap triggers come from.

Thanks for the help in advance..

Thanks all, I just wanted to make sure my thinking was correct. 

"So the creature doesn't die, it just leaves the battlefield.
The ability "When Geralf's Mindcrusher enters the battlefield, target player puts the top five cards of his or her library into his or her graveyard." is triggered again though."

This was what I was planning on doing.

My ? is if I have Geralf's Mindcrusher on the field w/o any +1/1, If I use a card like Ghostly Flicker that "Exile two target artifacts, creatures, and/or lands you control, then return those cards to the battlefield under your control."  Does Geralf's Mindcrusher come back on to the field with the +1/1.  Does Exile mean die? 

Thanks in Advance.
