Overview of Selects: What Is A Mold‑A‑Rama?

This episode (a curated replay of Stuff You Should Know) explains Mold‑A‑Rama — the vintage vending machines that melt, mold and blow‑form a hollow plastic figurine on demand. Hosts Josh Clark and Charles “Chuck” Bryant trace the device’s origin, how the machines work, why they became a 1960s sensation at world’s fairs and theme parks, and how a surprising number of original machines still operate today at zoos and tourist attractions.

Main takeaways

  • Mold‑A‑Rama machines are on‑demand injection blow‑molding vending machines that produce a hollow plastic toy right in front of you.
  • The concept grew from a small business (Tyke J. Miller) that made individual figurines starting in the 1930s; the molded‑toy vending idea exploded at world’s fairs in the 1960s.
  • About 200 machines were built in the 1960s; many of those original units are still in service and owned by family operators and small companies.
  • Machines are mechanically complex and maintenance‑heavy (hydraulics, steam heating, molten plastic vats), which is why they were expensive to make and required dedicated operators.
  • There’s a small but enthusiastic collector and operator community; dozens of machines are still active (notably in Toledo and other Midwestern and tourist locations).

History and cultural context

  • Origin story: Tyke J. Miller (Quincy, Illinois) and his wife made and sold individual plaster figurines starting in 1937; WWII disruptions helped spur U.S. production of small figures.
  • Transition to plastic and injection‑blow technology in the 1950s/60s. Miller’s company produced popular lines (e.g., “Earth Invaders” / Miller Aliens).
  • Mold‑A‑Rama debuted as a novelty at the 1962 Seattle World’s Fair and became hugely popular at the 1964–65 New York World’s Fair. Branded, licensed versions were used by companies (Disney, Sinclair, etc.).
  • ARA (Automatic Retailers of America / later Aramark) manufactured the machines through the 1960s; they stopped in the early 1970s and sold many units to independent operators.

How a Mold‑A‑Rama works (simplified)

  • Molding method: injection blow‑molding (a hybrid of injection molding and blow molding).
  • Key components: two matched mold halves, a vat of molten plastic pellets (kept at ~225–250°F by steam coils), hydraulics, compressed air system.
  • Process:
    1. Two mold halves close to form a hollow cavity (a negative of the figurine).
    2. Hot plastic is injected into the cavity.
    3. Compressed air is blown in to press the plastic to the mold walls and to expel excess plastic out the bottom (creating a hollow piece and returning excess to the vat).
    4. The toy is cooled briefly (machines instruct you to hold it upside down while cooling to avoid hot drips) and then dispensed.
  • Notes: The machines smell strongly of melted plastic; historically they were kept outdoors because of fumes and heat. They require regular refills, cleaning and mechanical upkeep.

Where to find them and today’s operators

  • Active locations: zoos, tourist attractions, theme parks, rest stops — especially in the Midwest and Florida. Toledo (Ohio) is repeatedly mentioned (Toledo Zoo, Children’s Wonderland/Tam O’Shanter).
  • Waymarking.com lists coordinates for many operational machines.
  • Modern operators / companies:
    • Replication Devices (family business descended from early buyers; reportedly operates 60–70 machines).
    • Mold‑A‑Rama, Inc. / William A. Jones Company (family ownership; about 60 machines in Midwest and elsewhere).
    • Independent operators and creative repurposers (Rotofugi’s “Roto‑O‑Matic” in Chicago; Disney imagineers and hobbyists have built custom units).
  • Economics: machines were expensive to build in the 1960s (~$3,600 in 1962, roughly $30k in modern dollars). A single machine can still produce significant cash flow at tourist sites (example: San Antonio Zoo estimate of ~130,000 figurines/year).

Popular designs, collectors and trivia

  • Designs: Many hundreds of molds exist (estimates vary — one collector estimated ~300 designs; another counted about 196 original molds). Molds could be commissioned for festivals, parks, brand mascots, local landmarks, etc. Examples: St. Louis Arch, Titan missile, Oscar Mayer Wienermobile, local festival pumpkins, zoo animals, mermaids, and retro novelty figures (aliens, dinosaurs).
  • Customization: Each machine normally uses one mold at a time — you get the same statue until the mold is swapped. Color could be changed by refilling with different colored pellets.
  • Cultural tie-ins: The Purple People Eater figure and other novelty toys were part of 1950s pop culture (song/figure connections discussed in the episode).
  • Collectors: Enthusiasts maintain photo archives, YouTube videos and databases; some own multiple machines or whole collections (e.g., “Moldville” projects).

Notable facts & memorable details

  • Original production run of machines: roughly 1962–1969; most still in use were built during that era.
  • Safety & experience: machines warn you to hold the new figurine upside down while it cools because of hot plastic drip risk; the smell of fresh molded plastic is a distinct part of the experience.
  • Price evolution: originally 50¢ in the early 1960s (equivalent to about $4 in 2017 dollars); many machines now charge about $2.
  • Tyke Miller later invented the “Golden Goat,” an early recycling machine that accepted aluminum cans and paid out money — a forward‑looking idea decades before mainstream recycling.

Recommendations / what to do next

  • Want to see one? Check Waymarking or search “Mold‑A‑Rama” plus “zoo,” “world’s fair,” or a nearby tourist attraction. Look for YouTube videos to watch the process (many fans film the machines and the toy forming).
  • If you enjoy nostalgia and mechanical curiosities, seek out a Mold‑A‑Rama — the live process is the main appeal more than the figurine itself.
  • For collectors or event organizers: a commissioned mold or a repurposed machine is possible, but expect significant maintenance and operational requirements.

Notable quotes from the episode

  • “A factory in a case.” — a succinct listener/host description of one of the machine’s charms.
  • “An on‑demand injection blow‑molded plastic toy dispenser.” — the technical short definition.
