Rubik's Cube Woes

>"GAH!"
>Twilight twists one side, only to ruin the perfectly straight green side of the cube.
>"Okay, maybe this way..."
>This makes the orange side line up, but the remainder is a disorganized mess.
>Twilight's face flushes in frustration.
>Of all the things you had to bring with you from Earth, it was a Rubik's Cube.
>You were giggling silently to yourself as the mare grew more frustrated over time.
>She had roughly a dozen books open around her, all of them about solving puzzles.
>Brain-Busters for Fillies, Puzzles 101, Advanced Riddles and Quizzes...
>"Grrrr...Anon!"
>You looked at her, grinning like a fool.
"Yes?"
>"No fair giving me an unsolvable puzzle!"
>You shook your head, hand out.
>Twilight nearly threw it at you, the cube coming to rest in your hand with quite a bit of force.
>You looked at it, turned a few times...then showed her your handiwork.
>A perfectly level cube, colors all on their correct sides.
>"Wh...but, how!?" Twilight demanded, looking the cube over for signs of tampering.
>You merely grinned as you mixed it back up.
"My only hint: Any Rubik's Cube can be solved in 20 moves or less, from any combination."
>You gave it back to the unicorn, and you could have sworn she was about to cry.
>You then sat back into your chair and continued to watch the show.
>The mare sat there all night, twisting the puzzle cube left and right.
>She almost had it once or twice, before twisting it the wrong way and wrecking it again.
>"CELESTIA DANG IT!" The mare roared, waking you up.
"Twi, seriously, c'mon now." You said with a yawn.
>"No, I have to get this!" She said, ignoring the growl her stomach just made.
"Eat something first?"
>"No." She replied, twisting it again.
>One side solved, five more utterly ruined.
>The concept of 'breaking' one side to fix them all hadn't occurred to her at any point throughout her puzzle solving.
>The mare growled in anger, throwing the cube at you.
>"To Tartarus with it, you win Anon!"
>You sighed.
"Twilight, watch."
>She glared at you, then the cube.
>You turned it twice to the left, three times up, once to the right, three more to the left...
>And were left with a solved cube.
"Twenty turns or *less*, Twi."
>The mare burst into literal flames.
>"HOW DID YOU DO THAT!?"
>You leapt backwards, keeping the very-flammable chair between you and the mare.
"I solved it?" You replied, confused. "You were thinking too much about it!"
>She extinguished just as quickly, stomping down the stairs for a late night snack.
>Twilight came back upstairs, sandwich in her magic aura.
>She was pointedly ignoring both you and the cube.
>"...mix it up again."
"...what?"
>"Mix it up again." She replied simply. "I'm going to solve this bucking thing."
>You sighed, hiding it behind your back and randomly mixing it up.
>You then gave the mare the randomized cube, which she took.
>She scarfed down the sandwich, and put the cube on her nightstand.
>"Later."
>You sighed in relief, going down the stairs to your room.
>"I still think you cheated, Anonymous!"
>You simply laughed, settling in for bed.
>You could hear her turning and twisting the cube all throughout the night.
