The sound has been used in over 58,000 videos. From monetary things, like racking up a monthly lifestyle spend of rent, utilities, and weekend brunches, to more existential calculations, like why they let their feelings get hurt and how many times they can keep doing something annoying. The trend has now evolved to people using it to try to calculate things. 2 to describe the panic you felt as a child when your mom left you alone at the register to "just grab one more thing." The sound caught on, and even grocery store workers are using it to show how they interact with children waiting for their parents at the register. In a completely separate trend, users are pretending to calculate all sorts of things to the sound of items being scanned at the register of a store. The equations lurking in the background of the Reading Rainbow trend isn't the only math that had its moment on TikTok this week. This trend is essentially TikTok's version of the "woman thinking about math" meme that first went viral back in 2016, but the combination of the Space filter and Reading Rainbow song add a uniquely homey twist to its internet source material. It made reading fun and interactive, and because of this it's often used by teachers in the classroom. The average TikTok user might be too young to recognize the nostalgic source material of the trend, but Reading Rainbow was a popular educational PBS show that aired from 1983 to 2006. Some of my favorite examples of the trend include video that reads, "when someone is trying to explain the rules of a board game to me," and TikTok that says, "when the airport sign says Arrival or Departures, but I am Arriving for my Departure." Some experiences are, in fact, universal. The trend specifically uses the part of the song that goes, "Butterfly in the sky / I can go twice as high." So far, the audio has been used in over 236,000 videos.

READING RAINBOW FULL
The filter is paired with the Reading Rainbow theme song for the full effect. The concept is simple: TikTokkers write a confusing sentiment and use the Space filter, which duplicates your face and places them among the stars with a fiery planet and mathematical equation in the background. This week's inescapable TikTok trend combines classroom aesthetics and the Reading Rainbow theme song to describe inexplicable situations. Two mathematical trends went viral, while Patsy Cline's "Crazy" sparked some collective catharsis across our FYPs.
