a magnet machine
Bookmarked 538 weeks ago this machine manipulates small spherical rare earth magnets slicing one at a time from the end of a long chain moving it around a bit then dropping it back to re-connect at the tail end of the chainit also demonstrates a little snippet of science called eddy currents watch how slowly the magnet falls through the aluminum tube compared to falling through air: the falling magnet generates an electrical current in the tube and that current in turn generates a magnetic field that opposes the movement of the magnet slowing it down dramatically see http:enwikipediaorgwikieddy_current if you want morei made this machine for my father-in-law for his 75th birthday: astute viewers equipped with video analysis software and way too much time on their hands might find that the magnet drops 75mm from the tip of the slicer until caught by the lifter and that the lifter then drops it through a 75mm long aluminum tubethese magnets are currently a popular toy and can be purchased on the web or in stores usually in a set of 216 which makes a 6x6x6 cube many different brands exist: zen magnets http:zenmagnetscom buckyballs http:wwwgetbuckyballscom nanodots http:wwwthenanodotscom neo cube http:wwwtheneocubecom and more i highly recommend this toy watch some videos at the above sitesi used a plastic drywall anchor for the main screw drive that pulls the chain of magnets through the machine the 2 other driven axles -- the slicer and and the lifter -- are geared directly to the screw drive steven garrison039s gear cutting method was invaluable to make the gears operate smoothly see http:wwwspiralsbystevecomgearsphp the lifter is based on a standard four bar linkage a film advance mechanism but was modified to dip very low before lifting back up and stroking its straight vertical line at the topsee http:wwwflickrcomphotosdogrocketsets72157626544506603 for still photos of building iti don039t know who first figured out that 5mm spherical rare earth magnets could be so much fun but whoever they are i thank them |

how to reveal subatomic particles at home nova
Bookmarked 573 weeks ago here039s a way you can reveal subatomic particles that are shooting in front of your eyes all the timecredits:produced animated and edited bygreg kestina special thanks to:anna rothschildlauren aguirreari danieldemonstration and lighting technician:allen crockettoriginal footage wgbh educational foundation 2015media credits:pond5videoblocksmicroscopy apm music musicfreesoundorg sfxwhere to buy dry ice:us dry ice distributor directory: http:wwwdryicedirectorycomusahtmoutside us: http:wwwdryicedirectorycomworldhtmsome grocery stores also carry dry iceexperiment instructions:materials: jar amp lid sponge 91 rubbing alcohol or greater purity not 70 permanent black marker flashlight and dry ice step 1: stuff the sponge in the bottom of the jar so it doesnt fall down when the jar is turned upside-down step 2: pour a bit of alcohol on the sponge but not too much that it will drip or fall when turned upside-down step 3: color as much of the inside of the lid black as you can this is so there is contrast with the droplets which will appear white as they reflect the flashlights light thin black paper attached to the lid may also work but it must be thin enough so the cold lid still cools down the bottom of the jar step 4: put the lid on the jar step 5: put on well-insulated gloves and pour out a pile of dry ice step 6: place the jar upside-down on the dry ice you may want to surround the edge of the lid with dry ice so it cools down faster step 7: shine your flashlight over the lid try various angles to get best visibility of droplets step 8: turn off all other lights step 9: look for lines of droplets you should be able to see droplets in the vapor falling down to the lid like snow but a few times a minute or more frequently you will see a line of droplets appear and fall down to the lid when you see a line it was from a subatomic particle shooting through your jarscientific notes: the setup here is a simple version of a cloud chamber: http:youtubeako0ry6klty subatomic particles include both elementary particles such as electrons and muons as well as nuclei such as protons or alpha particles quotthe smallest and most fundamental building blocks of matterquot refers to the former the pieces of atoms from exploded stars include predominantly protons alpha particles and some heavier nuclei the showers of subatomic particles are called air showers while the subatomic particles that eventually reach the earth are mostly muons electrons positrons and photons higher up in the shower protons neutrons pions and kaons are also present cosmic rays are the high energy particles that bombard the earths atmosphere creating air showers when a charged particle passes through the alcohol vapor some of it is ionized becomes electrically charged and the neighboring vapor is attracted to the ions forming visible droplets this is the disturbance that muons or electrons create as they pass through the vapor |

the dakota fire hole - stealth fire
Bookmarked 547 weeks ago what if i told you that you could make a fire that only you could see any passers-by will be totally oblivious to the presence of you and your fire if you want to get into stealth camping build a fire during gale force winds or just want to lay low then the 039dakota fire hole039 is just what you need first things first you039ll need to dig a pretty deep hole about 2 to 3 feet deep is a good standard but the bigger the fire you039re planning to build the deeper and wider you039ll have to dig so its ultimately up to your discretion i039ll be making a small personal fire so i039ll go 2 foot deep and 15 feet wideas long as you go balls deep and don039t be a bitch about it you can get the hole dug in 5 minutes flat i would suggest using some form of entrenching tool you can use a stick and your bare hands but that will take significantly longer and you039ll probably want to kill yourself halfway through out of frustration now step 2 you039ll need to dig a smaller hole about 1 foot away from the first hole you don039t need to dig as deep for this one but a depth of 15 feet is a best practice this hole will connect to the primary hole via a tunnel the purpose of this secondary hole and tunnel is to allow oxygen to flow into the fire as the heat and flames of spewing out of the bigger hole won039t allow any oxygen to enter from above this secondary hole also allows you to blow oxygen into the fire yourself with your breath without risking burning your eyebrows off if you chose to do that over the primary hole keep tunneling your way through until you reach the other sidebut don039t stop there keep digging away at the edges until its big enough for you to fit your arm through like a cheap hooker the bigger the tunnel the more oxygen that can enter meaning a more sustainable firenow that039s all done it039s time to build a fire the same practices of traditional fire making still apply a raised wooden platform to keep your fire off the ground which will burn down into a layer of embers over time utilize dead dry materials that have been hanging above the ground y039all already know the deal make the fire as you would make it on the surface you can fiddle about with the structure of the fire in anyway you see fit make a tipi a perimeter a log cabin build sup to you man if you want to cook over this type of fire then it039s just a simple matter of placing thick living green branches either over the top of the hole or jam them into the side of the walls living green materials won039t burn over the fire so your cookware will be safe to rest upon itthere039s a common misconception that these types of underground fires produce no smoke this isn039t strictly true an underground fire does hotter and more intensely than one that039s exposed to a colder atmosphere on the surface and that does limit its smoke emissions there039s a lot of chemistry involved in explaining why that is so i039ll save that for another video don039t want to go too off track here but if we refer back to the list of smoke generators i included in my signal and rescue video wet materials resinous and green materials will still produce smoke so it039s best to utilize the driest and deadest possible materials you can find if you really want to limit your visibility the smokeless fire pit comes from a rather unique way of building fire we think of fire building as a bottom up process we build a base fire and then add material on top of it for a smokeless fire we need to flip things upside down and have our fuelwood on the bottom with our fire on top the fire on top is started with copious amounts of kindling constantly fed with dry small twigs and dry wood shavings directly on top of the fire which will burn the large pieces of fuelwood below the reason this produces no smoke is because as the air flow from the secondary hole works its way up through the fuel wood it pushes all the gases and vapors which we call smoke which come from the moisture resins and oils contained within the fuelwood the air pushes it up into the hot flames where it burns off because of the heat intensity of underground flames if those gases and vapors didn039t have to travel upwards through the flame like in a traditional fire then you would have a smokey fire when you039re done be a gent and fill the hole back up no need to break people039s ankles as they pass on by in the future peace bros if you desire then you can pack all of the mud you039ve dug up on to the outskirts of your hole to give yourself a large wall to help you conceal the tips of your flames if they ever reach high enough to emerge out of the hole ------------------------------------outdoor skills for wilderness survival bushcraft hiking and recreational campingtwitter: wwwtwittercomalfieaestheticsfacebook: wwwfacebookcomalfietheaestheticgoogle: wwwplusgooglecomalfieaesthetics |
