Princess Luna and Princess Cadence had been granted access to the underside of the test chamber.
Cadence accidentally turned the spectrometer to 110%.
The scientist pony in one of the control rooms said, "We'll take it from here."
Princess Cadence said, "What have we done?"
Princess Luna said, "Just listen to what's going on upstairs."
The scientist pony said, "Power to stage 1 emitters in three, two, one."
A yellow beam shot into the anomalous array lighting the chamber.
The princesses saw the beam shoot down in the glass and they looked on the view-screen and see the barrels rotate.
The princesses heard the same scientist pony say, "I'm seeing a predictable phase array."
A moment later, they heard the third scientist pony say, "Stage 2 emitters activating, now."
The barrels that were rotating, shot electricity into the beam and into the glass.
The second scientist pony said, "Sweetie Belle, we cannot predict how long the system can operate at this level, nor how long the readings will take. We are asking you and your friends to please work as quickly as you can."
The third scientist pony said, "Overhead capacitors to 105%. Uh, it's probably not a problem, but I'm showing full discrepancy."
The first scientist pony said, "Well, no it's well within acceptable bounds, and we are sustaining the sequence."
Princess Cadence turned to Princess Luna and said, "They are going to get themselves killed."
Princess Luna said, "We can't interrupt the test because the cart is above us now."
