We Cut Up Glowsticks To See How Fireflies Make Light

The chemical reaction that fireflies use to create light (bioluminescence) is something you can recreate in a lab. Chemiluminescence produces light without heat, and we only need a couple of glowsticks to make it happen. To find out why we’re cutting up glowsticks, check out the latest Big Ideas episode 👉 https://youtu.be/ilpmpCEDK8A #youtubeshorts #bioluminescence #deeplook #fireflies

What happens if you eat a silica gel packet? - Vivian Jiang

Explore the science of silica gel, and find out why these packets are everywhere and if they're actually dangerous to ingest. -- Of the many, many things we’re not supposed to snack on, perhaps the most common forbidden food is silica gel. This tiny packet pops up in packaging for everything — from TVs and guitar cases to sunscreen and snack foods. So why is silica gel everywhere, and what would actually happen if you ate it? Vivian Jiang digs into the science of this pervasive product. Lesson by Vivian Jiang, directed by Denys Spolitak.

Why Do Animals Glow? The Science of Bioluminescence

Some animals don’t just survive in the dark — they light it up. From deep-sea predators to insects on the forest floor, living organisms across the planet have evolved the ability to glow. This phenomenon, known as bioluminescence, has appeared independently dozens of times in nature. But why? In this episode, we break down how bioluminescence works at the molecular level. Special compounds like Luciferin react with enzymes called Luciferase to produce light — no electricity required. ---+ For all things Earth Month, check out our playlist: https://www.youtube.com/playlist?list=PLnNZYWyBGJ1F8ofFm4H9UTrHxqU8zngK4 👉 Donate to KQED, the public media station that makes Deep Look: https://donate.kqed.org/deeplook SIGN UP for Deep Look’s newsletter, Nature Unseen: https://bit.ly/NatureUnseenSignUp SUBSCRIBE: https://www.youtube.com/@KQEDDeepLook?sub_confirmation=1 ---+ Find a transcript on KQED Science: https://www.kqed.org/science/2000492/why-do-animals-glow-the-science-of-bioluminescence ---+ More great Deep Look episodes: Why Mammals Gave Up On Laying Eggs https://www.youtube.com/watch?v=ilpmpCEDK8A I Simulated Insect Vision and It Got WEIRD https://www.youtube.com/watch?v=5UCQoFO9dIk Can You Spot These Insane Camouflaged Animals? https://www.youtube.com/watch?v=Gpvc5ZX5B08 ---+ Thank you to our top Patreon supporters ($10+ per month)!
