Podcast Summary: "How Does a Straw Work?"
Who Smarted? – January 28, 2026
Host: Adam Tex Davis
Co-host: Jerry Colbert
Guest Character: Marvin Chester Stone (Inventor of the Paper Straw)
Main Theme & Purpose
This lively episode of "Who Smarted?" explores the science, history, and social impact of the drinking straw—a simple tool with a surprisingly complex story. The hosts use their signature humor and interactive trivia style to show how straws evolved, why they’re both beloved and banned, and the clever science behind how they work. Listeners are taken on a fun and fact-filled adventure to discover how atmospheric pressure lets us sip, why ancient people used straws, and why drinking through one won’t work in space!
Key Discussion Points & Insights
1. Straws: From Hero to Outlaw (00:27–04:19)
-
Environmental Concerns
- Straws have become controversial due to their environmental impact, especially plastic straws.
- "Most straws are made with plastic and are harmful for the environment." (Adam Tex Davis, 03:02)
- Although plastic straws make up only about 4% of global plastic waste, their sheer quantity (hundreds of millions discarded daily) means they contribute significantly to pollution.
-
Not All Straw is Bad
- The confusion between drinking straws and the straw animals eat.
- "Plastic straws, not so much. They're hurting the environment... People are fine with your straw. Plastic straws, not so much." (Adam Tex Davis, 03:31)
- True or False trivia clears misconception: most plastic waste isn't from straws, but the problem is growing due to single-use culture.
2. The Viral Video That Changed Straws Forever (05:19–06:05)
- In 2015, a video went viral showing scientists removing a straw from a sea turtle’s nose.
- This spurred public efforts and business changes to reduce plastic straw usage.
- Notable quote:
"The video showed marine biologists removing a discarded plastic straw from a sea turtle's nose. Since then, there have been efforts to end plastic straw waste." (Adam Tex Davis, 05:39)
3. Modern Solutions and Alternatives (06:09–06:53)
- Paper straws and biodegradable options are making a comeback.
- Some people, especially those with disabilities, still rely on straws.
- Reusable straws (metal, sturdy plastic) are promoted for environmental benefits.
4. History of the Drinking Straw (07:04–09:46)
-
Ancient Beginnings
- Straws date back about 5,000 years to the ancient Sumerians (now Iraq).
- They drank beer through straws to avoid barley and oat clumps.
- "Way back then, everyone drank beer—even those under age 21." (Adam Tex Davis, 08:09)
-
Straw Prestige
- Fancy straws made from precious metals appeared in elite burials for the afterlife.
- Straws were also used in Egypt, East Asia, and by Mayans (for blowing bubbles in chocolate drinks).
-
Early Modern Straws
- By the 1800s, people drank through plant-based straws but faced issues: falling apart, altering drink taste, needing multiples per drink (straw flavor not so appealing!).
- Notable comedic exchange:
- "Straw breaks apart too easily, straw is uncomfortable on the tongue, or straw is dirty..." (Adam Tex Davis, 09:13)
- "It's always good to have lots of straw handy. Am I right, fellas?” (Jerry Colbert, 09:34)
5. The Paper and Bendable Straw Inventions (10:02–12:12)
-
Marvin Chester Stone (10:04)
- Invented the modern paper straw: "Legend has it, he wrapped some paper around a pencil, covered it in wax, and invented the modern paper straw." (Adam Tex Davis, 10:29)
-
Joseph Friedman & the Bendable Straw (11:09)
- Friedman improved convenience using a screw and floss to create grooves (bendy straws).
- "The indentations allowed the straw to bend without breaking." (Adam Tex Davis, 11:15)
- First popularized in hospitals so patients could drink lying down.
-
The Plastic Straw Boom
- 1960s: Cheap, strong plastic straws skyrocket in popularity—leading to today’s environmental dilemma.
6. Straws and Science: How Do They Really Work? (15:33–17:42)
-
Why Use a Straw?
- Hygiene (can tops), convenience (ice, avoiding spills), accessibility (hospital patients, disabilities).
- "Drinking from a straw does have benefits... it can make drinking a lot easier." (Adam Tex Davis, 15:33)
-
The Science of Sipping
- Notable explanation:
- "When you suck from a straw, what exactly are you sucking up?... You're not actually sucking up liquid, but the air inside the straw." (Adam Tex Davis, 16:20)
- Atmospheric pressure pushes the liquid into the straw as you remove the air.
- Demonstrated interactively with a suggestion to try sipping directly from the cup without a straw (harder than it seems!).
- No air, no pressure, no sip!
- Notable explanation:
-
Why Straws Don’t Work in Space
- “With no atmospheric pressure, there's nothing to push the liquid into your straw, making drinking through it impossible.” (Adam Tex Davis, 17:45)
- On the space station, straws can work thanks to contained pressure.
7. Memorable Quotes & Humorous Moments
- “Straw again, not that kind of Straw, Smartypants...” (Adam Tex Davis, recurring joke)
- "Oh, we could use more straw here. My friend Donkey had a rough sleep last night." (Jerry Colbert, 06:05)
- "I am Marvin Chester Stone, and I was trying to enjoy my mint julep, but now I'm utterly disgusted." (Marvin Chester Stone, 10:04)
- “That's because with a straw, you're not actually sucking up liquid, but the air inside the straw. Whoa.” (Adam Tex Davis, 16:43)
