• [BONUS] Fluorescent milk, ‘liquid’ glass, and studying ripples in spacetime: Tiny Show and Tell Us #33

  In this episode of Tiny Show and Tell Us, we get to the bottom of if glass is a liquid or a solid and why riboflavin makes milk fluorescent. Then we talk about the Laser Interferometer Space Antenna (LISA) — the first space-based observatory that NASA scientists and their collaborators are sending up into space to detect and study gravitational waves, better known as “ripples in spacetime.” We need your stories — they're what make these bonus episodes possible!

• How stunning 19th century dyes led to today's drugs

  In 1856, after yet another day of disappointing experiments, a chemist named William Henry Perkin was cleaning up his glassware when he made a discovery that would harken a new — and colorful — era of science and industry. Just 18 years old, Perkin was a promising young student in a prestigious lab at the Royal College of Chemistry in London and he was supposed to be figuring out a way to make a chemical compound called quinine. Despite his best efforts, Perkin was coming up empty — or rather — producing a lot of dirty dishes with little to show for it. But he did notice that there was a curious goop in one of his flasks, and it turned a brilliant shade of purple in the wash. Intrigued, Perkin decided to try dyeing a swatch of silk with his serendipitous solution. Although he had failed yet again to produce quinine, Perkin had created the very first synthetic dye and launched a scientific industry that is still bringing new drugs and dyes to market today.Send us your science facts, news, or other stories for a chance to be featured on an upcoming Tiny Show and Tell Us bonus episode.

• [BONUS] Wasp versus beetle and blood iron recycling: Tiny Show and Tell Us #32

  In this episode of Tiny Show and Tell Us, a listener on “team wasp” writes in with some interesting info on USDA wasps for pesticide-free pest control and we learn about some wasp versus beetle drama. Then we talk about how our red blood cells use and expel iron, and how a huge percentage of the iron we get is from broken down blood cells.We need your stories — they're what make these bonus episodes possible!
