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
- How soap bubbles escape the sink
- How bubbles give birth to rainbows
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
Here’s a lovely step-by-step guide for making your own delicious, tangy, and not-contaminated-by-bad-bacteria 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.
An apple a day keeps the doctor away. Red sky in the morning, sailors take warning. What can i say, sometimes its just easier to follow advice when it’s delivered in a rhyme scheme.
On today’s show, K+K & guest host Emily Gilliland explore some of the more modern Old Wives Tales, and discuss the science behind why they are or aren’t true.
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!

Science Fact or Science Fiction (the quiz game™) is back! On today’s episode, K+K test Keiren Bond on her carnivorous plant knowledge, with questions like:
- Can a Venus Fly Trap count?
- Would any plant eat bugs if you mushed them into an artisanal organic soup?
- Would a pitcher plant prefer to eat a Montane Tree Shrew, or its poop?
In part 2 of their exploration of these space oddities, K+K talk to guest host Emily Gilliland about what would happen if our sun spontaneously imploded, how anyone falling into a black hole would turn into spaghetti, and what it means to exist in time, but not in space. They even attempt to explain how, to an observer moving faster, time (literally!) moves slower, by making Emily do (proverbial) back-flips in space.
Have you ever been falling into a black hole and thought, “how did this infinite curve in spacetime even get here, anyway?” Well, the next time you’re hurdling towards the infinitely dense Singularity, which exists only in time but not in space and is possibly a hole in the 4-dimensional universe, you can listen to this episode!
In Part 1 of their journey through outer space, K+K explore how Black Holes are formed, discuss the recent detection of their gravitational waves, and interview Isaac Newton and Albert Einstein about light, gravity, and the fluffy pink frosting of spacetime.
