Warnings Active: Orb Hitting Body, Orb Receiver

This stage is the introduction to the energy orb; the basic concept is that there is an emitter and a receiver. This area is one of the first places you can die, specifically by touching the orb - which will vaporize you. The orange portal is located below the emitter; make a blue portal directly above the reciever. Look for an orange glow on the ceiling above the receiver to pinpoint the area for your portal. Walk onto the now-powered lift and continue into the elevator.
