In which John Green teaches you about the war that was supposed to end all wars. Instead, it solved nothing and set the stage for the world to be back at war just a couple of decades later. As an added bonus, World War I changed the way people look at the world, and normalized cynicism and irony. John will teach you how the assassination of an Austrian Archduke kicked off a new kind of war that involved more nations and more people than any war that came before. New technology like machine guns, airplanes, tanks, and poison gas made killing more efficient than ever. Trench warfare and modern weapons led to battles in which tens of thousands of soldiers were killed in a day, with no ground gained for either side. World War I washed away the last vestiges of 19th-century Romanticism and paved the way for the 20th-century modernism that we all know and find to be cold and off-putting. While there may not be much upside to WWI, at least it inspired George M. Cohan to write the awesome song, "Over There."

What happens when you decrease the pressure around a liquid? It boils. Water boils at room temperature once the pressure is low enough. What is interesting is that this decreases the temperature of the liquid. The fastest molecules escape, leaving the slower ones behind. Using this trick with liquid nitrogen, it is possible to create solid nitrogen at a temperature of -210C. We then poured the solid and liquid nitrogen mixture onto a tray of water. The surface of the water became so cold that CO2 solidified out of the atmosphere on its surface. Then, since CO2 does not pass through the liquid phase at atmospheric pressure, it was propelled on the water surface by jets of gas as it sublimed. Huge thanks to the Palais de la Decouverte.

In which John Green teaches you about European Imperialism in the 19th century. European powers started to create colonial empires way back in the 16th century, but businesses really took off in the 19th century, especially in Asia and Africa. During the 1800s, European powers carved out spheres of influence in China, India, and pretty much all of Africa. While all of the major (and some minor) powers in Europe participated in this new imperialism, England was by far the most dominant, once able to claim that the "sun never set on the British Empire." Also, they went to war for the right to continue to sell opium to the people of China. Twice. John will teach you how these empires managed to leverage the advances of the Industrial Revolution to build vast, wealth-generating empires. As it turns out, improved medicine, steam engines, and better guns were crucial in the 19th-century conquests. Also, the willingness to exploit and abuse the people and resources of so-called "primitive" nations was very helpful in the whole enterprise.

Please Click to Tweet! http://bit.ly/MACAWesomeSLOWMO I apologize for the video being a couple of minutes longer... but it took months of planning and preparation to do this. I wanted to leave a bit in there about the boat so I wouldn t lose the memories! The noise was awful though (Macaws have a horrible song). I didn t know most of the rain in the Amazon comes from the Atlantic! So this is what happens when you combine a battery operated Miro LC320S high speed camera with an incredibly specific spot of dirt that Macaws LOVE. It took several days and lots of modes of transportation to get there, but we took a new MIRO (http://www.visionresearch.com/Products/High-Speed-Cameras/Phantom-Miro-M320S/) to one of the most remote research facilities in the Peruvian Rainforest. The footage we obtained was incredible. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~ GET SMARTER SECTION: How to get there yourself!: I coordinated the travel with Rainforest Expeditions http://www.perunature.com/ Tell them Destin sent you.

In which John Green teaches you about Nationalism. Nationalism was everywhere in the 19th century, as people all over the world carved new nation-states out of old empires. Nationalist leaders changed the way people thought of themselves and the places they lived by reinventing education, military service, and the relationship between government and governed. In Japan, the traditional feudal society underwent a long transformation over the course of about 300 years to become a modern nation-state. John follows the course of Japanese history from the emergence of the Tokugawa Shogunate to the Meiji Restoration and covers Nationalism in many other countries along the way. All this, plus a special guest appearance, plus the return of an old friend on an extra-special episode of Crash Course.

Well it depends on your definition of plasma, but there are certainly ions in a flame, formed as molecules collide with each other at high speed, sometimes knocking electrons off of their atoms. Special thanks to the Palais de la Decouverte for helping me perform this experiment. Using tens of thousands of volts on two metal plates, we created a strong electric field around the plasma. This pulled positive ions in one direction and negative ions in the other direction elongating the flame horizontally and causing it to flicker like a "papillon" (butterfly). Then we showed that much longer sparks can be made through the flame than through air since the ions increase the conductivity.

You have company, or maybe a hot date, coming over to your pad and you want to create a cooler-than-normal table top so look around your house for some table top decor inspiration! I challenged myself to set two, quick and easy, on-the-fly tablescapes, (one flirty bohemian world traveler and the other more clean with two white scarves as the tablecloth) using only things I had in my home. These table settings were featured on Dwell Magazine here: http://www.dwell.com/articles/mr-kate-sets-a-dwell-table.html Try using vegetables or house plants in the place of fresh flowers and ta da, you re ready for your dinner party!...or hot date.

Answer video: https://www.youtube.com/watch?v=BickMFHAZR0 The longest vertical straw you can use is 10.3 m http://www.youtube.com/watch?v=HUmZrtiXDik This is because the weight of water in the straw must be supported by the pressure difference at its two ends. At the bottom, the pressure is atmospheric, and at the top, the lowest pressure you can create is a perfect vacuum (pressure = 0). Atmospheric pressure can support a water column about 10m high - BUT with 0 pressure at the top, the water would start boiling. This is called cavitation and it obviously can t be happening in trees. After I posted the straw video, I received a lot of questions about how trees could be taler than 10m. I assumed there was a simple answer because there are plenty of trees taller than that. But as I asked around and read articles about it, I couldn t really find an explanation I was happy with. Maybe there is not a continuous water column inside the tree, so each section only lifts water a little ways? This could be but it seems to require a series of pump mechanisms, and how would you join this pump sections together? Perhaps capillary action is holding the water up? But the xylem tubes in a tree seem too wide (~50 um) for this effect to be significant. Maybe osmotic pressure could push the water from below rather than sucking it up from above? But some trees live in mangroves, where there is much higher solute concentration in the sea water than in their roots, so osmosis would work the other way. Eventually I spoke to a plant biologist and sorted this all out, but I wanted to give you a little back to school challenge. How do you think this could work?

This manicure looks more advanced than it is, it s easy! The heart tip, or as I like to call the Heart On is really simple to create using the brush that comes with the nail polish bottle. I used Gelish gel manicure colors and cured them in the Sensationail LED light but you could do this manicure with regular nail polish and add the 3D rhinestones and pearls.
