Late at night, Casey works on her science project in her bedroom. Joan comes in to check on Casey, and observes that while ice skating requires tremendous artistry, she cannot get past the skimpy outfits, which set women back 50 years. Casey promises her mom that she will never, ever wear an outfit like that.

Back at the ice rink, Ann operates the video camera and films Casey reciting an introduction to her project. After several false starts, Casey eventually uses her physics to perform an impressive jump.

Inspired, Casey approaches Tina and announces that she would like to perform in the recital. Tina instructs Casey to show up tonight at 5:30, cutting close to a Harvard alumni tea Casey is attending at 3:00. Tina also offers to lend Casey an outfit if she stops by her house.

Although Casey has shown her dedication to ice skating, here we see that she remains equally devoted to science, which conveniently involves watching slow-motion footage of teen girls wearing outfits so revealing that her mom believes they set women back 50 years. Unfortunately, while Joan seems very intelligent, she obviously knows very little about movies and fails to realize that by voicing her worst nightmare out loud ("If I ever saw you squeeze into one of those things, I'd probably start crying"), she guarantees that she will eventually see Casey squeeze into one of those "twinky little outfits."

It is, in fact, only surprising that Casey is not wearing the dreaded twinky outfit in the very next scene, although she is back on the ice at the Harwood Skating Club. As perhaps the most mortifying 53 seconds in modern cinema, Casey's video introduction can only be seen to be believed. Nevertheless, it is interesting to see the fetishistic gaze of her own camera pointed back at Casey, especially since Ann is the one wielding it now; emboldened by her newfound dominance, Ann even goes so far as announcing, "You know... you look kinda hot!" in the middle of recording Casey's presentation, ensuring an awkward experience for any of their classmates who might eventually view this tape.

But the lovesick Ann is rendered speechless when Casey lands her big jump, possibly because it is so amazingly rare to see Casey do something right. However, Ann regains composure when she remembers that she is merely an Ice Cream Princess, and her only chance to glide will be on Casey's coattails: "When you sign with Nike, remember I wear size 6 1/2!" Additionally, in accordance with the inspiring themes of this film, it's nice to imagine that Nike is falling all over themselves to launch an ad campaign starring this bumbling dork who has landed one jump in her life.

Nevertheless, this is quite a milestone for Casey, and signals growing conflict between her academic life and her skating life. With the Harvard alumni tea just a few hours before the recital AND the mention of borrowing clothes from Tina, it seems inevitable that Chekhov's Twinky Outfit will go off a few acts earlier than expected. Meanwhile, Tina obviously wishes an actual Chekhov's Gun would make an appearance around the third time Casey bops into her office with nettlesome eagerness.

Even if Casey's grasp of basic physics principles was correct, one might imagine that in the 100+ years that figure skating has existed as a competitive sport, someone would already have figured out how ice skating works. In the field of professional sports from baseball to tennis to swimming, experts have broken down every kind of pitch, serve, and dive to its most basic mathematical component. Baseball statistician Nate Silver was so successful in his implementation of the PECOTA (Player Empirical Comparison and Optimization Test Algorithm, a sabermetric system for forecasting Major League Baseball player performance) that he applied his findings to the 2008 United States Presidential Election and successfully predicted the outcome of the race.

All we're saying is, Casey ought to know what the moment of inertia is.
