Episode Overview
In this lively and nostalgic mailbag edition of Decoder Ring, Willa Paskin and the team decode three listener-submitted cultural mysteries:
- The Yo-Yo Assembly Craze: Why did mysterious yo-yo masters tour American schools in the 1990s, whipping kids into a yo-yo-buying frenzy?
- The Rise (and Decline) of the Sandbox: How did corralling kids into pits of sand become a standard part of American childhood—and why has it faded?
- The Modern Encore: Why do encores at concerts feel so perfunctory and staged, and how did this tradition start?
The episode is rich in personal recollections, expert interviews, and archival audio, blending history, economics, and the sociology of play.
1. The Yo-Yo Assembly Mystery
[03:29–29:28]
Listener Question
Sebastian from Montana remembers a mysterious assembly in elementary school, circa late 1990s, where a charismatic man performed yo-yo tricks, sold yo-yos to every kid, and then vanished. Why did this happen? Was it educational, or just showy salesmanship?
Personal Memories & Simpsons Parallels
- Evan Chung shares: He too experienced the same event at his suburban Chicago school, echoing Sebastian’s account.
- Reference to a 1992 Simpsons episode parodying the phenomenon.
"This is basically a captive audience sales presentation to the most impressionable group of people you could probably imagine..."
— Willa Paskin, [06:50]
The Traveling Yo-Yo Man: Real and Ubiquitous
- Evan locates Dazzling Dave (Dave Schulte), a National Yo-Yo Master who’s toured the world performing and selling yo-yos in schools for 25+ years.
"I've been to Japan, Korea, France, Australia, all over the US doing yo-yo assemblies and demonstrations."
— Dazzling Dave, [11:09]
The Origins of Yo-Yo Craze
Pedro Flores: The Filipino Pioneer
-
Pedro Flores (b. 1896, Philippines) immigrated to the US, popularized the yo-yo through hands-on community demos in the 1920s.
"He made the yo-yo what it is today."
— Rob Pena, author “Pedro’s Yo Yos”, [12:27] -
The company was soon bought by Donald Duncan, who industrialized the approach: teams systematically mapped and targeted schools and toy stores.
"You plot out the city, you know, you plotted all the schools and all the stores. And once you did that, then the next day you'd start."
— Dale Oliver, former yo-yo salesman, [18:01]
From Sidewalks to School Gymnasiums
- In the 1950s–60s, yo-yo men were banned from school property, so they waited for kids outside.
- By the 1980s: Science centers and regulations changed, and yo-yo assemblies entered the classroom. Tricks were paired with lessons on physics, and assemblies paid for by selling yo-yos.
The 1998 Yo-Yo Boom
- 1998 marked the all-time peak for global yo-yo sales—fueled almost entirely by school assemblies.
"More yo-yos were sold in 1998 than any other time."
— Dazzling Dave, [24:37]
The Sales Pitch
- Schools typically chose to waive the presenter’s fee in exchange for letting him sell yo-yos to students.
- About 65% of kids would buy a yo-yo; schools received a cut of the sales.
"So if it's a school of, you know, 300 kids, you're selling quite a few yo-yos."
— Dazzling Dave, [26:53]
Ethics and Legacy
-
There’s an inherent tension: “Is this education or captive-audience sales?”
-
Some schools opt out to avoid highlighting economic inequalities among students.
-
A Simpsons teacher voice echoes a real-world concern:
"I question the educational value of this assembly."
— Simpsons clip, [27:32] -
Dale Oliver defends: “Well, you're going to turn your TV set off. It's just another avenue…it’s no worse than just seeing a toy commercial on Saturday morning.” [28:14]
-
Ultimately, the yo-yo assembly is both a blast of innocent fun and a business scheme—but one with some surprising virtues: skill-building, resilience, and peer mentorship.
"I just see so much of the benefits of the kids learning how to do it…they've grown, they've learned. They just feel better about themselves."
— Dazzling Dave, [28:48]
2. How Did Sandboxes Become a Thing?
[29:28–43:01]
Listener Question
Aileen from Alameda wonders: Why do we buy sand, put it in boxes, and let our kids play in it? Where did sandboxes come from, especially when there’s a beach nearby?
Cultural Universality and Odd Specificity
- Panel reminisces about classic turtle-shaped plastic sandboxes in suburban backyards.
"There's a turtle-shaped piece of plastic with a weird half lid that never worked. And that's a sandbox."
— Alexandra Lang, architectural critic, [30:41]
Sandbox Origins: The German “Sand Garden”
-
Alexandra Lang traces the sandbox back to c.1850s Germany and the innovations of Frederich Fröbel, inventor of kindergarten ("children's garden").
"[Fröbel]...came up with a series of toys and blocks and other exercises that teachers could lead students through."
— Lang, [32:17] -
The first “sand gardens” were open-air installations for play and learning—the sandbox as a “microcosm of the earth.”
"The sandbox is kind of a microcosm of the earth to teach things about how water flows, how you can build a structure, all of this other stuff."
— Lang, [33:07]
Expansion and Americanization
-
American reformers imported the concept in the 1880s to get kids out of busy streets, sparking the playground movement.
"The sand gardens kickstart the larger playground movement in America. They are the first move to give kids something to do off the streets."
— Lang, [36:18] -
From vast sand gardens, the concept narrowed to the more familiar, contained sandbox as playgrounds became standardized.
The Sandbox’s Heyday—and Decline
- Up until the 1970s, the sandbox was a playground staple, especially for younger children.
- Concerns over maintenance, hygiene (rats, cat waste), and lawsuits in the 1970s–80s led to their removal from many public spaces.
"The issue with sandboxes is not so much physical safety as it is the cost of maintenance. People start becoming worried about...rats nesting in the sandbox, and also toxoplasmosis from cats..."
— Lang, [38:30]
The Private, Miniaturized Sandbox
- Enter the 1979 Little Tikes Turtle Sandbox: protected by a shell-lid, ubiquitous in backyards.
"The turtle sandbox was really everywhere, I think, because the turtle shell was a cover."
— Lang, [39:33]
Social Costs and Virtual Sandboxes
-
Private sandboxes restrict spontaneous, multi-age, and cross-neighborhood play inherent to the urban sand garden.
"When you have a suburban backyard...it's really like limited in its social value and limited in size."
— Lang, [39:57] -
In today’s world, true communal sandboxes cluster in “designer” playgrounds—sometimes a marker of privilege and investment, as in Brooklyn Bridge Park.
"The sandbox…has become a kind of status marker."
— Katie Shepherd, [41:47] -
Parallel migration: from physical sandboxes to digital “sandbox games” like Minecraft—open-ended, creative, and libertarian in spirit.
"I think it's one of the ironies that as the number of sandboxes in the country has diminished, there has been a rise in those sandbox games."
— Lang, [42:29]
3. Why Are Encores a Thing at Concerts?
[43:01–60:20]
Listener Question
Kate from Indianapolis, a live music fan, wonders: Why do bands always perform encores, even when everyone knows it’s part of the script? Isn’t it supposed to be spontaneous?
The Ritual: Scripted Surprise
- The familiar routine: band “ends” show, skips big hits, crowd claps, band predictably returns and plays the hits.
- "It's all pre-planned. Everyone at the show knows this. And yet we go through the motions every time."
— Willa Paskin, [44:44]
Historical Roots: From Opera to Rock
-
18th-century opera houses: rowdier, freewheeling; audiences demanded repetition of favorite arias by shouting “encore” (French for "again").
"If they wanted to hear more music, they would ask for it."
— Brian Wise, journalist/musicologist, [46:28] -
This sometimes disrupted performances; by the 1920s, institutions like the Metropolitan Opera banned encores mid-performance.
Piano Recitals: The Legacy Encore
- At recitals (e.g., Rachmaninoff), performing a signature encore after the program became an institution.
"Going to a piano recital, people expect a certain number of encores. It's just part of the experience."
— Brian Wise, [49:32]
The Rock Era: From Spontaneity to Ritual
-
In the early days of rock, package tours and tight schedules left no room for encores (cf. “Elvis has left the building,” [50:59]).
-
Woodstock (‘69) changed the game—larger crowds, longer sets.
-
The shift to arenas and stadium performances after the 1970s: tickets got pricier, shows more spectacular.
-
Alice Cooper’s “Billion Dollar Babies” tour (1973) institutionalized the fake ending and the scripted encore:
“The spontaneous call for encores...got a little bit ritualized because it just seemed like good business....And audiences...knew it was coming, so you didn’t have to work for it anymore.”
— Michael Walker, music journalist, [55:02] -
Initially some resistance (Rolling Stones, The Who), but soon, encores became inescapable:
"It became a tradition. And at this point, nobody really wants to break that tradition. Because you don't want to piss the audience off, especially if they paid all this money."
— Michael Walker, [55:52]
Today: Cliché, Subversion, and Reinvention
-
In recent years, some artists refuse to play encores, explicitly telling audiences it’s “stupid and fake.”
-
Yet most bands stick to the ritual—out of nostalgia, showmanship, or the practical need for a “pee break”.
"There is something fun about it. It's not like encores are all bad. … it is fun to have a moment and then get a little bit more music."
— Willa Paskin, [58:25] -
Surprise or authenticity: Lady Gaga’s “Mayhem Ball” ends with her taking off makeup and clothes backstage while singing—creating a more intimate, behind-the-scenes feel.
"She's sort of singing the song as Stephanie instead of Gaga, and that is a really, really incredible way for that show to end."
— Kate, listener, [60:08]
Notable Quotes & Moments
- [06:50] Willa Paskin: “This is basically a captive audience sales presentation to the most impressionable group of people you could probably imagine…”
- [24:37] Dazzling Dave: “Yes, 1998 was the height of the yo-yo boom. Across the world, more yo-yos were sold in 1998 than any other time.”
- [33:07] Alexandra Lang: “The sandbox is kind of a microcosm of the earth to teach things about how water flows, how you can build a structure, all of this other stuff.”
- [39:33] Alexandra Lang: "The turtle sandbox was really everywhere, I think, because the turtle shell was a cover."
- [55:02] Michael Walker: “The spontaneous call for encores when you got into stadiums got a little bit ritualized because it just seemed like good business.”
- [58:25] Willa Paskin: “There is something fun about it. It's not like encores are all bad… it is fun to have a moment and then get a little bit more music.”
