Overview
In this fun and educational episode for kids and families, the Who Smarted? team explores the science and history of paint—how it’s made, what it’s made of, and the wild history behind paint pigments. Trusty Narrator, with help from paint expert Jade (and recurring, cheeky interruptions from Bob Rosela), unpacks the four key ingredients of paint, reveals why you shouldn’t paint your studio with watercolors or finger paint, and shares some surprising (and slightly gross) facts about how paint colors were created throughout history.

The Four Ingredients of Paint
(A clear thread runs through the episode to keep track of paint ingredients. Each gets its spotlight.)
1. Binder
- What is it? The “glue” of the paint—makes it stick to surfaces.
- Historical Binders: Natural materials like eggs, beeswax, and oils from linseeds or soybeans.
- Scientific Note: Stronger binders make more opaque paint; watercolors are light because their binders are weak.
Quote:
> “A binder, also called a resin, is the paint’s glue.”
— Jade [02:56] - Watercolors: Great for art (see-through effect) but not for painting rooms [03:11–03:39].
2. Solvent
- What is it? The liquid that makes paint spreadable—it evaporates as the paint dries.
- Examples: Water (for most paints kids use), oil or chemicals (for durable, hard-to-clean paints).
- Cleaning Up: Water-based paints (like finger paint) are easier to clean; oil-based require scrubbing [06:06].
Memorable Exchange:
> Trusty Narrator: “Do you remember having to really scrub off finger paint? Not really. Right?”
> Jade: “That’s because the solvent in finger paints is water.”
[06:18–06:24]
3. Additives
- What are they? Modify or boost properties (e.g., quick-drying, mildew resistance, environmental safety).
- Latex Paint: Most common for homes; strong binder, water solvent, lots of useful additives.
Quote:
> “It’s affordable, fast drying, environmentally friendly, and has additives that enhance the paint, doing things like preventing moisture and mildew.”
— Jade [08:14]
4. Pigment
- What is it? The “color” in the paint.
- Where do pigments come from? Historically, sources included berries, roots, minerals—and some surprising (gross) things.
Quote:
> “Pigments have been a major paint ingredient since the beginning.”
— Jade [09:56]
2. Types of Paint (and Why Not All Are Room-Friendly)
- Watercolor: Pretty, but weak; soaks into surfaces, not good for walls [02:41–03:39].
- Finger Paint: Fun for kids, easy clean-up, but not for big surfaces—doesn’t spread well [04:47–06:40].
- Acrylic and Alkyd: Artist paints; bold, hard to clean, expensive—better for art, not wall painting [07:38].
- Latex: The household hero—sticks well, easy to use, the top pick for most people [08:14].
3. Pigment Origins: Disgusting, Surprising, and Fascinating!
-
Ancient Paint: Used over 100,000 years ago—earliest found in a South African cave [10:06–10:31].
-
Strange Pigment Ingredients:
- Blood: Obvious red pigment.
- Cow Urine: Used for vibrant yellows (even Van Gogh!), later banned when its origins were revealed [11:37].
- Crushed Egyptian Mummies: “Mummy brown”—used until the 1960s.
Memorable Quotes:
> “If you want something that'll wow them, I recommend our line of Smarty paints made with blood, cow urine, and crushed Egyptian mummies.”
— Bob Rosela [11:05]
> “Mummy brown continued to be made until sometime in the 1960s, when the manufacturer simply ran out of its supply of mummies.”
— Jade [12:15]
-
Modern Pigments: Now made from metals, plants, and chemicals—safer, less gross, more colors [12:44].
Notable Quotes & Memorable Moments
- “Where’s that music coming from?” — Jade kicking off the surreal, silly interruptions by Bob Rosela [00:30].
- “No, instead, let’s dwell on what won’t work in here. Watercolors.” — Jade [01:15]
- “Today, many colors come from metals, organic materials such as plants, and chemical compounds—not crushed mummies.” — Jade [12:44]
- “Actually, I’m gonna go with the Happy Little Trees.” — Trusty Narrator, referencing the running Bob Ross joke and revealing his color choice [13:00].
