Dimensional Ripper - Everlook

In order to create the transporter, you need to be an Engineer with a skill level of 260 as well as have that special training that you can only get from the goblins of the Steamwheedle Cartel. If you have the skills, talk to Zap Farflinger in Everlook by the teleporter to learn the recipe.

You're forgetting perhaps the best failure in the game! I have gotten a two hour debuff from this contraption before. It's called "Evil Twin" and reads "You have been replaced by your evil twin." when moused over.
This is just one of the many engineering jokes and it happens to be related to the original Star Trek episode "Mirror, Mirror."

A failure can also paralyze you and change your character model. I've been turned into Murlocs, Gnolls and Kobolds.

Also, the fire DoT doesn't put you in combat, so eating will keep you alive.
