Music By: Scott & Brendo “Somewhere” http://bit.ly/ScottBrendoiTunes See their YouTube page: http://bit.ly/YTScottDW Project Inspired By: SFHandyman's Instructable article: http://bit.ly/IBSFHandyman Project History & More Info: Who doesn't love gummy candy, and who doesn't love LEGO? 5 years ago I was fascinated with it, wondering how it was made, and what gave it its gummy texture. It feels so good on the teeth to bite into it, and my kids go crazy for them .. so I spent a bit of time researching how they're made commercially. My biggest motivation for doing this was to see if we could make our own at home, and I'm actually still trying to figure out how to make gelatin and corn syrup from scratch, so if I can figure out how to do that, maybe I'll show how to do it in another project video. Only a small handful of you have ever seen the LEGO Gummy video I made in 2010, and that's because it was nearly 5 years ago, before I really got serious about making videos. I took it off my channel in 2012 because I had full intentions of making a better version, so here it is .. 3 years later! :) Now I wanted to make candies that made people look twice, and LEGO bricks instantly came to mind because what's more awesome than LEGO and gummy put together? But I wasn't sure where could you get a mold for making LEGO bricks. Surfing around the internet, I stumbled across an awesome Instructable by SFHandyman: http://bit.ly/IBSFHandyman To my amazement, not only had he shown how to make a mold for making LEGO candy, he also made LEGO gummies as well! I played around with loads of variations in recipes to see what texture and tastes I liked the best. And I've kept experimenting off and on for the last 4 years, using my kids and wife for feedback. They gobble them up no matter what variations I use, but I've finally settled on 1/2 cup of very cold water, 1/4 cup of corn syrup, 2 packets of unflavored gelatin, and 1 pack of Jell-O. I've found that the corn syrup seems to help smooth out the texture and the taste. If you try making this recipe, it's very important to start the gelatin in cold water. Stir it up, then let it sit for 5 minutes before you turn on the heat. Otherwise, you'll get gobby clumps of undissolved gelatin in your syrup that doesn't look very appetizing. I originally made my silicone mold with a 2 part mix from a special effects supply company. I used real LEGO bricks set on a LEGO base, and built a makeshift retaining wall with bricks and play-dough. I don't plan to make a tutorial on how to make the mold, but I want to do a video on how to make a silicone mold in general. It's amazing to see how much detail the silicone can transfer to the final gummy products. If you look closely at my candies you can even see the little “LEGO” text on top of the gummy LEGO studs. To make sour gummies, we often add citric acid. They are incredible! But if you don't have citric acid, try taking SFHandyman's suggestion and add vitamin C. The citric and ascorbic acids in the vitamins sour them the same way, which actually makes them taste just as great, and enriches them with vitamin C as well.

Music by: TheFatRat ("Xenogenesis”) Licenced by Tasty http://youtube.com/tasty Project Inspired By: Mikey77's Instructable on Ooogoo: http://www.instructables.com/id/How-To-Make-Your-Own-Sugru-Substitute/ Project History & More Info: Casting silicone is very expensive, so over the years I tried to find a cheaper alternative to making LEGO candy molds (https://goo.gl/XcLbep). I started off trying silicone caulk from the hardware store, but globs of it would take weeks and weeks to finally firm up. That wasn't acceptable because I needed something that would harden in 24 hours or less. About 3 years ago I came across an Instructable by Mikey77 showing that mixing corn starch into the silicone caulk could be used to make it firm up in under an hour. I did a number of experiments of my own, and eventually found out that corn starch wasn't actually needed at all, but that all you needed was to add a little food coloring. I still like to use corn starch though because it helps prevent the caulk from sticking to my hands as I work with it. The stuff is really hard to get off if it sticks to skin!

The Most Radioactive Places on Earth
 
11:18
Who on Earth is exposed to the most ionizing radiation? Check out Audible: http://bit.ly/AudibleVe I'm filming a documentary for TV about how Uranium and radioactivity have shaped the modern world. It will be broadcast in mid-2015, details to come. The filming took me to the most radioactive places on Earth (and some places, which surprisingly aren't as radioactive as you'd think). Chernobyl and Fukushima were incredible to see as they present post-apocalyptic landscapes. I also visited nuclear power plants, research reactors, Marie Curie's institute, Einstein's apartment, nuclear medicine areas of hospitals, uranium mines, nuclear bomb sites, and interviewed numerous experts. Notes about measuring radiation: Sieverts are a measure of 'effective dose' - that means they measure the biological impact of the energy transferred to tissues from radiation. Obviously I owe a debt to the fantastic chart made by xkcd, which inspired my visual approach to this video. https://xkcd.com/radiation/ DOSES MAY VARY The level of radiation varies widely around the world depending mainly on altitude and geology (excluding nuclear accidents). Estimates of particular doses also vary. All numbers reported in this video should be taken as order of magnitude only. The most contentious claim may be that smokers receive the highest dose of ionizing radiation. This is not a whole body dose, but a dose to the lungs as specified in the video.

I always thought of the characters in our story as the scientists and maybe the uranium nucleus itself. It was only through making the documentary that I realized the real hero of the story is the neutron. Without a neutral nuclear particle, it would be virtually impossible to release the energy from the nucleus. But with it, and the idea of a chain reaction, nuclear energy went from science fiction to reality. That is something I had not grasped as clearly before and it motivated me to make this video.

If you want to try this experiment, instructions are here: link.springer.com/article/10.1007/s12650-016-0383-5 The standard theory of quantum mechanics leaves a bit to be desired. As Richard Feynman put it, "I think I can safely say that no one understands quantum mechanics." This is because observations of experiments have led us to a theory that contradicts common sense. The wave function contains all the information that is knowable about a particle, yet it can only be used to calculate probabilities of where a particle will likely turn up. It can't give us an actual account of where the particle went or where it will be at some later time. Some have suggested that this theory is incomplete. Maybe something is going on beneath the radar of standard quantum theory and somehow producing the appearance of randomness and uncertainty without actually being random or uncertain. Theories of this sort are called hidden variable theories because they propose entities that aren't observable. One such theory is pilot wave theory, first proposed by de Broglie, but later developed by Bohm. The idea here is that a particle oscillates, creating a wave. It then interacts with the wave and this complex interaction determines its motion. Experiments using silicone oil droplets on a vibrating bath provide a remarkable physical realization of pilot wave theories. They give us a physical picture of what the quantum world might look like if this is what's going on - and this theory is still deterministic. The particle is never in two places at once and there is no randomness. Edited by Robert Dahlem Sound design by A Shell in the Pit

This project should only be attempted with adequate knowledge and training, proper protective safety gear, and in a fire resistant area with adequate ventilation. The heat from the foundry can easily burn, and inhaling excessive amounts of zinc fumes can cause metal fume fever. Use caution and common sense. Use of this video content is at your own risk. Music By: TheFatRat - Licensed by Tasty Song Title: Xenogenesis Music Video: https://www.youtube.com/watch?v=_nabH... Label Channel: http://youtube.com/tasty" Project Inspired By: An indirect suggestion my dad made for me to try and make something practical out of brass. He didn't expect I'd end up making these! Project History & More Info: The weather has cooled off quite a bit, which has turned my interest back to keeping warm by casting metal. This time round I wanted to play with higher temperature metals, like brass. So I made a trip to a local shooting range, and salvaged a whole bucket-load of spent brass casings. Quite a few people have asked whether my backyard foundry can melt brass, and I was curious myself, so I threw a few handfuls of casings into a crucible and fired them up. I tried using lump charcoal because it burns hotter and faster than briquettes, and a clay crucible purchased from the internet because it withstands heat better, and lasts longer than steel. I was impressed that the brass melted down without hesitation, and I was able to easily cast mini brass muffins the same day. A couple things worth mentioning are that the melting point of brass is around the boiling point of zinc. I noticed this in real-life when the metal started bubbling, and shooting out white flames. I wasn't sure what it was until I looked it up, but it was most likely zinc oxide fumes being released. Zinc Oxide can be toxic in large quantities, and although it's never happened to me, claims are that it can cause metal fume fever, which gives flu like symptoms. You should also know that brass is over 3 times heavier than aluminum, so expect the crucible to have a lot more weight to it, making it harder to handle. My dad was visiting at the time and confirmed my thoughts about it by suggesting I try making something more practical and useful. So I thought it would be fun to make some "Brass Knuckle" paperweights. I looked online at different varieties of brass knuckles, then drew my own version in photoshop, and used the "Styro-Slicer" and the lost-foam casting technique to make a rough pair of knuckles. I cast another pair the same way, and spent another 8 hours sanding and buffing them up to a mirror finish, then wondered how I could take them to the next level. Spikes seemed like a cool idea, inspired by a picture I saw on a google image search, so I stopped at an alternative clothing store and picked up a spiked choker collar, and repurposed the spikes for my piece of metal art. These are not designed or intended to be used as weapons. Possession of Brass Knuckles is illegal in most countries, (but not where I live), however I created these simply for artistic expression, and use them mainly as workshop décor. (paperweights).

E. Knowles Middleton Absolute Zero and the Conquest of Cold by Tom Shachtman The Science of Measurement, A Historical Survey by Herbert Arthur Klein Lehrbuch der Chemie by Jöns Jakob Berzelius Script: As an Australian-Canadian the Fahrenheit temperature scale always seemsed a bit arbitrary. I mean why does water freeze at 32 degrees? And what exactly does zero represent? According to many sources the Fahrenheit scale was defined by setting zero degrees equal to the temperature of an ice, salt, and water mixture and 100 degrees being roughly equal to human body temperature. But that isn’t true. The real story is much more interesting, and scientific... August 14th 1701 was almost certainly the worst day in the life of fifteen year-old Daniel Gabriel Fahrenheit. On that day both of his parents died suddenly from mushroom poisoning. He was sent from Poland, where he lived, to Amsterdam to become an apprentice bookkeeper. But Fahrenheit couldn’t stand his apprenticeship and ran away so many times his employers put out a warrant for his arrest. Traveling from city to city around Europe, he became fascinated with scientific instruments and in particular thermometers. In 1708, possibly seeking help with the warrant, Fahrenheit met with the mayor of Copenhagen, who happened to be the famous astronomer Ole Romer. Romer is known for observing the eclipses of Jupiter’s moons and realizing that variations in the timing of those eclipses was caused by the time it took light to reach Earth. In other words, he found a way to accurately measure the finite speed of light. But more pertinent to this story, in 1702 Romer was housebound after breaking his leg. To pass the time he devised a new temperature scale with the freezing point of water at 7.5 degrees and body temperature at 22.5 degrees. This might seem odd until you consider that Romer wanted the boiling point of water to be 60 degrees (as an astronomer, he had experience dividing things by 60). If you take this scale, divide it in half, in half again, and in half once more, you find the freezing point of water 1/8th up the scale, and human body temperature 3/8th up the scale. So at their meeting in 1708, Fahrenheit learned of Romer’s temperature scale and adopted it as his own, adjusting it slightly because he found it “inconvenient and inelegant on account of the fractional numbers”. So he scaled them up to 8 and 24. That is the original Fahrenheit scale. He produced thermometers for some time using this scale. But then, at some later time Fahrenheit multiplied all numbers on his scale by four, setting freezing point to the now familiar 32 and body temperature to 96. It’s unclear exactly why he did this. He may just have wanted finer precision in his measurements but I think there was a better reason. You see, Fahrenheit was an excellent instrument maker. His thermometers agreed with each other precisely, at a time when that was unheard of. He pioneered the use of mercury as a measuring liquid, which has the benefit of a much higher boiling point than the alcohol used in most other thermometers at the time. For these accomplishments, he was inducted into the British Royal Society. And we know he read the works of Newton, Boyle, and Hooke, in which he would have come across the idea that a one degree increase in temperature should correspond to a specific fractional increase in the volume of the measuring liquid. And today a one degree Fahrenheit increase in temperature increases the volume of mercury by exactly one part in 10,000. Is this just a coincidence? We’ll probably never know for sure because as an instrument maker Fahrenheit was secretive about his methods. But I think the data strongly suggests this was the case. So what exactly did zero represent on the scales of Fahrenheit and Romer? By many accounts it’s the temperature of a salt, ice and water mixture. But there are different descriptions of these mixtures and none of them actually produces the temperature they’re supposed to. More likely I think they picked the coldest temperature in winter, set that as zero and later used ice and brine to calibrate new thermometers. Now his scale is only used regularly in the Cayman Islands, Bahamas, Belize, oh and the United States of America.

The great porn experiment | Gary Wilson | TEDxGlasgow
 
16:29
NOTE FROM TED: This talk contains several assertions that are not supported by academically respected studies in medicine and psychology. While some viewers might find advice provided in this talk to be helpful, please do not look to this talk for medical advice. In response to Philip Zimbardo's "The Demise of Guys?" TED talk, Gary Wilson asks whether our brains evolved to handle the hyperstimulation of today's Internet enticements. He also discusses the disturbing symptoms showing up in some heavy Internet users, the surprising reversal of those symptoms, and the science behind these 21st century phenomena. More About Gary Wilson Gary is host of www.yourbrainonporn.com. The site arose in response to a growing demand for solid scientific information by heavy Internet erotica users experiencing perplexing, unexpected effects: escalation to more extreme material, concentration difficulties, sexual performance problems, radical changes in sexual tastes, social anxiety, irritability, inability to stop, and obsessive-compulsive symptoms. As a physiology teacher with a particular interest in the latest neuroscience discoveries, Gary was aware that their symptoms might be the result of addiction-related brain changes. Applying the website's concepts of brain plasticity, many former users have braved withdrawal, reversed their symptoms and restored normal sexual responsiveness. The site has been linked to from hundreds of threads in forums from over thirty countries, with posts numbering in the thousands. Gary blogs for "Psychology Today" and "The Good Men Project" on the extreme plasticity of adolescent brains, the evolutionary context for today's flood of novel cyber "mates," and the neurochemical reasons why superstimulating Internet delivery has unexpected effects on the brain.

World's Roundest Object!
 
11:44
The world's roundest object helps solve the longest running problem in measurement -- how to define the kilogram. Support Veritasium on Patreon: http://bit.ly/VePatreon A kilogram isn't what it used to be. Literally. The original name for it was the 'grave', proposed in 1793 but it fell victim to the French Revolution like its creator, Lavoisier. So begins the tale of the most unusual SI unit. The kilogram is the only base unit with a prefix in its name, and the only one still defined by a physical artifact, the international prototype kilogram or IPK. But the problem with this definition has long been apparent. The IPK doesn't seem to maintain its mass compared to 40 similar cylinders minted at the same time. The goal is therefore to eliminate the kilogram's dependence on a physical object. Two main approaches are being considered to achieve this end: the Avogadro Project and the Watt Balance. The Avogadro project aims to redefine Avogadro's constant (currently defined by the kilogram -- the number of atoms in 12 g of carbon-12) and reverse the relationship so that the kilogram is precisely specified by Avogadro's constant. This method required creating the most perfect sphere on Earth. It is made out of a single crystal of silicon 28 atoms. By carefully measuring the diameter, the volume can be precisely specified. Since the atom spacing of silicon is well known, the number of atoms in a sphere can be accurately calculated. This allows for a very precise determination of Avogadro's constant. Special thanks to Katie Green, Dr. David Farrant, the CSIRO, and the National Measurment Institute for their help. Thanks also to Nessy Hill for filming and reviewing earlier drafts of this video. There is debate as to whether this is truly the roundest object ever created. The Gravity Probe-B rotors are also spherical with very low tolerances such that they may in fact be rounder.

We're kicking off our exploration of muscles with a look at the complex and important relationship between actin and myosin. Your smooth, cardiac, and skeletal muscles create movement by contracting and releasing in a process called the sliding filament model. Your skeletal muscles are constructed like a rope made of bundles of protein fibers, and that the smallest strands are your actin and myosin myofilaments. Its their use of calcium and ATP that causes the binding and unbinding that makes sarcomeres contract and relax.
