Summary
Hear about a slingshot launching payloads into space, the impressively modern looking world’s oldest pants, and how moth wings are able to absorb sound to avoid detection from bats.
A different kind of slingshot.

- “NASA to Test SpinLaunch, a Giant Slingshot for Launching Satellites Into Space” by Eric Mack
Very very old pants.
- “The world’s oldest pants are a 3,000-year-old engineering marvel” by Kiona Smith
- “The world’s oldest pants stitched together cultures from across Asia” by Bruce Bower
Moth sound absorbers.
- “Moth wing-inspired sound absorbing wallpaper in sight after breakthrough” by The University of Bristol
- “Moth wings as sound absorber metasurface” by Thomas R. Neil, Zhiyuan Shen, Daniel Robert, Bruce W. Drinkwater and Marc W. Holderied

| 0:00.0 | Hi, you're about to get smarter in just a few minutes with Curiosity Daily from Discovery. |
| 0:08.8 | Time flies when you're learning super cool stuff. I'm Nate. |
| 0:11.6 | And I'm Callie. If you're dropping in for the first time, |
| 0:14.0 | welcome to curiosity where we aim to blow your mind by helping you to grow your mind. |
| 0:17.8 | If you're a loyal listener, welcome back. |
| 0:19.8 | Today you'll learn about a slingshot launching payloads into space, the impressively modern-looking world's |
| 0:25.8 | oldest pants, and how mothwings are able to absorb sound to avoid detection from bats. |
| 0:32.3 | Without further ado, let's satisfy some curiosity. |
| 0:35.8 | Hey, do you remember those toys in jungle gyms? |
| 0:37.9 | They were called like merry-grounds or roundabouts, |
| 0:40.0 | but it was a circular platform with handles |
| 0:42.0 | and you could stand on them and spin. |
| 0:43.6 | Oh, those were so much fun. Though, I used to spend too quickly sometimes and then you'd get so queasy. |
| 0:49.6 | Well, what if that is the newest step in space exploration? |
| 0:54.0 | Getting queasy while spinning? |
| 0:56.0 | Well, a new startup called Spin Launch |
| 0:58.0 | has developed a system to launch payloads into low-Earth orbit, |
| 1:02.0 | the area in space that is 1,200 miles or less above the planet, |
| 1:06.0 | where things like the International Space Station orbit. |
| 1:08.3 | The new system uses centrifugal force from super fast rotations to launch payloads and if it works it could help us get into space more |
| 1:16.3 | affordably and with less impact on the environment. |
| 1:18.6 | Centrifugal force that's the outward force that comes when you spin something around a fixed point. |
