Is it a metal? Or is it METAL?!? (Like, the music. You have to say it with a growl to get the joke.) In today’s show, K+K attempt to stump the XRAY DJs with phrases that might describe an actual scientific element and its metallic properties, or might be the name of a Metallica song.
On part 2 of this series about bicycles, K+K answer: How do you build a frame that won’t snap in half when you’re doing sick bike tricks? What is Carbon Fiber, and why is it all the rage? How are air molecules like a McDonald’s ball pit, and why are they a cycler’s biggest nemesis? Plus, tricks and tips to help you counter air resistance, using SCIENCE!
Here in Portland, we love our bicycles! But what is it about these seemingly ordinary machines that makes us so energetically efficient? Join Kira & Keera (and Keera’s mom!) to learn how the pedals, tires, and gears of a bike work together to propel you 3x as fast as walking, without you having to put in any more effort!
Based on the way it gets your dishes sparkling clean, and makes all those fanciful rainbow-colored bubbles, one could be forgiven for thinking that soap is actually magic! But like pulling the curtain back on the Great Wizard of Oz, K+K explain how all of soap’s greatest tricks work, like:
How soap traps grease and dirt
Why slimy fat and burnt ashes are premium soap ingredients
So you’re ready to take the big leap, and start fermenting your own vegetables at home. Congratulations! This is an important time in any person’s life, and K+K want to make sure you have the support you need. In this episode, you’ll learn:
A fast, easy, and SAFE method for making sauerkraut
How to acquire good bacteria in your sauerkraut jar, without inviting in the pathogenic (a.k.a. icky) kind
What a “fermenting bacteria” is, and how they work their ferment-y magic
The epic-micro bacterial drama that plays out while you wait for your cabbage to become tangy, delicious, shelf-stable sauerkraut
Back when they were young, nervous, and pressed for on-air time, Kira & Keera did an episode of Everything of Interesting about the science of cannabis and its constituent chemicals. Today they revisit the subject, armed with a lot more knowledge and far more confidence.
In this episode, K+K cover the difference between Indica & Sativa, how THC and CBD affect your brain, and whether or not nature wants us to get high.
Have you ever moved things with your mind? How about communicated a thought telepathically, from your brain, directly to someone else’s brain?
If you’ve used Brain-Computer Interface technology, (or if you’re a Jedi) the answer is probably… yes! But if there were wires and a computer involved, does that count as true telepathic or telekenetic abilities? And will they let you into Jedi Academy with something like this on your head?
Thank you so much to Joel Murphy from OpenBCI for explaining the ins and outs of Brain Computer Interface, and for reading Keera’s brainwaves!
