    #4 - The Billion Ant Mega Colony and the Biggest War on Earth

    S7:E15

    In nearly every corner of the Earth, ants wage war against each other. Their weapons are what nature gave them. Some have strong armour, deadly stingers or sharp mandibles. And then there is this tiny, and not very impressive ant. But it rules the biggest empire any ant has ever built. A colony spanning continents and fighting wars that leave millions of casualties. Let’s take a look at this unlikely warrioress: Linepithema humile, the Argentine ant.

    #5 - What If We Nuke a City?

    S7:E16

    As you may have noticed, we like to blow stuff up on this channel. So when the International Red Cross approached us to collaborate on a video about nuclear weapons, we were more than excited. Until we did the research. It turned out we were a bit oblivious off the real impact of nuclear weapons in the real world, on a real city. And especially, how helpless even the most developed nations on earth would be if an attack occurred today. So hopefully this video demonstrates how extremely non fun a real world nuclear attack would be, without being to gruesome. This collaboration was a blast (no pun intended) and we want to say a huge thank you to the International Red Cross!

    #7 - This Is NOT An Anti Meat Video

    S13:E2

    Most of us love animals but also eat meat. Unfortunately, most animals we eat live in truly horrible conditions. We don’t torture them for better meat, just for cheaper meat. If we all paid just a bit more, we could avoid most animal suffering – often just for a few cents per meal. What would it truly cost us to avoid animal torture and still eat meat?

    S13:E7

    Fentanyl is the deadliest illegal drug in US history by far. It’s often described as the ultimate high, but it’s actually an inferior, short-lived, and brutally addictive version of heroin. In this video, we explore what opioids do to your brain and body, what it feels like to take them, and why so many people are dying from Fentanyl overdoses without ever choosing to take it.

    #11 - Why Is The US Dropping Billions Of Mutant Flies From The Sky?

    S13:E8

    A war has been raging for decades in the jungles of Panama, as we fight one of the most terrifying parasites on Earth. It is so relentless that our best defense is to drop 100 million radiation-blasted, flesh-eating flies from the sky – every week. It’s one of the most successful biological campaigns in history, but it’s a war we can never stop fighting… and one we can’t afford to lose.

    #22 - Trees Are So Weird

    S13:E21

    Trees are among the most extreme and successful forms of life on Earth. They build their bodies from thin air, move water with pressures that would crush a human, and grow using a fascinating system of living cables wrapped in layers of corpses. Under their bark lies a razor-thin strip of living cells, working endlessly to move water hundreds of meters, build indestructible wood, and coordinate millions of functions. How do trees work, and what are they even made of? What makes these ancient giants so resilient, and maybe even immortal?
