Atoms As Big As Mountains — Neutron Stars Explained
 
05:11
Neutron Stars are some of the strangest things in the Universe. Not quite massive enough to become black holes they are basically atoms as big as mountains with properties so extreme it's mind-blowing. And if you get too close to a neutron star you are in big trouble… Lots of you told us youtube doesn't tell you when we release new content. So we made a newsletter. No spam ever: http://eepurl.com/2bzP1 (Never miss a new video again) The music of the video can be found here: https://www.epicmountainmusic.bandcamp.com/track/neutron-star & https://www.soundcloud.com/epicmountain Videos, explaining things. Like evolution, time, space, global energy or our existence in this strange universe. We are a team of designers, journalists and musicians who want to make science look beautiful.

Music By: Jason Shaw (RP-KickedUpPumps) http://www.audionautix.com Project Inspired By: jasonklass http://youtu.be/r7uLVGrAt1M Project History & More Info: Char cloth is a fabric, like 100% cotton, that has been converted into a slow-burning fuel that can ignite at very low temperatures. The process of cooking the fabric, without burning it, is called pyrolysys. During pyrolysys, gasses such as hydrogen and methane are released from the fabric, and can be ignited and burned. The process of making char cloth is very similar to making wood gas, and the gas released can be captured and burned as fuel. Char cloth can be ignited by a single spark, that can in turn be used to ignite a tinder bundle to start a fire. Sometimes it's difficult to ignite tinder directly, and char cloth provides a means that makes the process extremely simple.

How To Make An Electrical Arc Furnace
 
07:41
How to hack flashlight batteries and a fire brick, into a desktop arc reaction chamber. ...For hobby metal melting, and for science! Some quick links to a few of the materials I used: [✓] Lantern battery: http://amzn.to/2cgnKxN [✓] Forstner Bit: http://amzn.to/2c1Ja3V [✓] 3/8 Drill bit: http://amzn.to/2cgl6rL Endcard Links: Micro Welder: https://goo.gl/ZmccT9 Laser Blowgun: https://goo.gl/lu3o0M Magic Mud: https://goo.gl/5dtyXP Matchbox Rockets: https://goo.gl/jguunj See What Else I’m Up To: Instagram: https://goo.gl/C0Q1YU Facebook: http://bit.ly/FBTheKingOfRandom Business Inquiries: For business and sponsorship inquiries please contact us directly: http://www.youtube.com/thekingofrandom/about WARNING: Risk of electric shock, fire hazards, and toxic fumes depending on what material you're working with. Dust from refractory brick should never be inhaled, as it can damage lungs and cause long term respiratory challenges. This project can reach temperatures in excess of 3,000ºF (1,648ºC) which is well beyond the melting point of hobbyists. Caution, care and expert planning are required to mitigate risks. Have fun, but always think ahead, and remember that every project you try is at your own risk. Music By: Scott & Brendo (“Photographs” - Instrumental) http://bit.ly/ScottBrendoiTunes Project Inspired By: This project was originally inspired by Theo Grey and his book, "Mad Science". After seeing the concept, I couldn't find any information anywhere on the internet or in libraries about arc furnace experiments, so I set out on my own to achieve these results. Project History & More Info: If you're wondering where you can get fire brick locally, try a quick Google search for “refractory materials” in your city. I called a couple of companies near me and asked if they'd sell to the general public. All of them said yes. If you can't find anything locally, try searching major hardwares stores online. They usually have inventory online that they don't carry in the stores. The insulating fire bricks I got were the 3” x 4.5” x 9” Alumina-Silicate Brick variety. I got a box of 10 for $33, effectively making them around $3.30 each. I went one step further and designed the furnace so that 2 of them could be made from one brick, cutting the cost in half, making each furnace a pro-rated $1.65 each! They're extremely lightweight, and capable of withstanding the temperatures used in steel working, but soft enough you can cut and carve them with kitchen utensils if you need to. In reading and studying history a bit, I learned that some of the earliest forms of light were made using carbon arc lighting. Large amounts of electricity were pumped through carbon rods, making a bright arc and providing light. To scavenge carbon electrodes, I took a lesson from NurdRage (youtube.com/NurdRage) a couple of years ago I saw his video on what could be scavenged from a carbon-zinc lantern battery (http://bit.ly/IBNurdRageBattery). It's useful to know what common everyday materials are made of, and these heavy duty batteries are containers packed with carbon rods, zinc metal, and manganese dioxide. I tucked the information in the back of my mind until now. In this project I tried melting the zinc casings from the lantern batteries, and casting them into a small ingot, formed with a mini muffin tray. Be cautious of the zinc oxide fumes produced. I haven't personally suffered any ill effects from working with it, but some people claim it can give flu like symptoms, or a fever if inhaled in large quantities. Zinc has a relatively low melting point 787.2°F (419.5°C), so the Arc Furnace is able to melt each casing into liquid zinc in around 5-10 seconds. That's amazing! I don't have an exact purpose for the zinc yet, but it's an easy metal to work with, easy to cast, and great to have on hand for a future projects. It's also one of the main metals used for making a simple carbon-zinc battery. The black stuff pulled out of the battery casings is manganese dioxide. It's a useful chemical for experiments with hydrogen peroxide, so it's worth hanging onto. Although I haven't verified it, I believe any stick welder can be used to power the mini arc furnace, and for most hobbyists, that would definitely be the easier and safer way to go. I just don't own a welder, so I used the one I made instead. You can see how to make it here: https://goo.gl/H0FWxE The longest I've run the unit continuously is around 3-4 minutes, and the electrodes get so hot at that point they can seriously burn your hands, or melt your gloves. I wouldn't recommend running it any longer than that.

Are ghost ships real? - Peter B. Campbell
 
05:01
View full lesson: http://ed.ted.com/lessons/are-ghost-ships-real-peter-b-campbell Please note: we are currently working on a fix for an error spotted in the video. The error relates to the behavior of the water filling the hole in the Mary Celeste's hull. The water would reach equilibrium with the outside water level, not cease filling at the hole. We thank you for your patience as we work on a fix. In 1884, the British steamer “Rumney” crashed into the French ship “Frigorifique.” Seeing their ship filling with water, the French crew climbed aboard the “Rumney.” But as they sailed towards port, a silent form emerged from the fog – the abandoned “Frigorifique,” seemingly back for revenge. So what happened? Peter B. Campbell investigates the fascinating phenomenon of ghost ships. Lesson by Peter B. Campbell, animation by Zedem Media.

Immune System, part 1: Crash Course A&P #45
 
09:13
Our final episodes of Anatomy & Physiology explore the way your body keeps all that complex, intricate stuff alive and healthy -- your immune system. The immune system’s responses begin with physical barriers like skin and mucous membranes, and when they’re not enough, there are phagocytes -- the neutrophils and macrophages. It also features the awesomely named natural killer cells and the inflammatory response, and we'll explain how all of these elements work together to save the day if you happen to slip on a banana peel.

Haitian Revolutions: Crash Course World History #30
 
12:35
Ideas like liberty, freedom, and self-determination were hot stuff in the late 18th century, as evidenced by our recent revolutionary videos. Although freedom was breaking out all over, many of the societies that were touting these ideas relied on slave labor. Few places in the world relied so heavily on slave labor as Saint-Domingue, France's most profitable colony. Slaves made up nearly 90% of Saint-Domingue's population, and in 1789 they couldn't help but hear about the revolution underway in France. All the talk of liberty, equality, and fraternity sounds pretty good to a person in bondage, and so the slaves rebelled. This led to not one but two revolutions, and ended up with France, the rebels, Britain, and Spain all fighting in the territory. Spoiler alert: the slaves won. So how did the slaves of what would become Haiti throw off the yoke of one of the world's great empires? John Green tells how they did it, and what it has meant in Haiti and in the rest of the world.
