Vortex Cannon Demolishes House « Wonderment Blog Jem Stansfield from BBC's Bang Goes the Theory has "put scientific theory to the test" with his Vortex Cannon. Filmed at 1300-fps, you can see the cannon knock down three different houses made of straw, stick, and brick with an explosive vortex ring. The vortex ring that comes out is not smoke, however. After detonating the explosive gas mixture of acetylene and oxygen, "one of the most dangerous gas mixes in the world," the ring forms from the pressure drop inside the vortex. Stansfield's cannon is probably too big for the average do-it-yourselfer, but Edwin Wise from Make Magazine has a few garage-friendly vortex cannons - the Tub Thumper, Barking Tube, and Big Bad Boom Cannon. Get the full PDF instructions or see Kipkay in action below, building Wise's first two vortex cannons.
Handmade Salt Pouches For The Shower Or Bath I love salt scrubs, especially this time of year when I want to slough off the dead skin from winter, and I equally love bath salts for the skin softening ingredients in them – but more often than not I find myself in the shower. These pouches are perfect for combining both bath salt and salt scrub into an exfoliating pouch I can bring into the shower, and they are simple to make. You can go a few different routes when making these so play around with your recipes and find your favorite. I made these for my mom for Mother’s Day so I added a few things for specific reasons. 1 cup sea salt – Coarse because it holds up better in the water for exfoliating1 cup Epsom salt – Anti-inflammatory, skin softener among other things1 cup powdered milk – Skin conditioner, gentle exfoliate1 cup baking soda – My mom has hard water, this will soften it15 drops of Peppermint essential oil – She is up before dawn and needs a pick-me-up A few different ideas for a mix: Start with 6 cheap washcloths.
1ℓimit – Faucet Design by Yonggu Do, Dohyung Kim & Sewon Oh & Yan... One Liter Limited 1ℓimit faucet looks more like an elegant test tube inverted on top of a tap. The glass tube holds exactly one liter of water, sufficient for a quick handwash. you knew i was going to make one. they are all over pinterest....(i still am not signed up for pinterest because i don't have time for one more thing but browsing is fun!) so we made one. i took a box of 64 crayons and took out the blacks and browns.i used another small box and doubled up on the good colors i liked and hot glued them to the top of our canvas. then we turned our blow dryer to hot on high. not long after you set the hair dryer by the crayons they get shiny and then the wax starts to melt! and it dries really quickly too. seriously. what could be happier than this?? GREAT project. loved it today is the first FULL day with ALL my kids in ALL day school.yeah...i am smiling as i type that. it's good. it's quiet. i am rockin' it. removing wallpaper.....making code for craft weekend stuff.....doing my hair....going to lunch..... it's all good. hooray for school!

Planting A Pineapple Did y’all know that you can take this and turn it into… This? And that this will eventually produce… This? Yes, I’m talking about turning your average, ordinary grocery store pineapple into a tropical showpiece within your home. Planting a Pineapple 1. 2. 3. In 24 months (sounds better than two years) it will look like this. You will have an actual, large, utterly delicious pineapple in 24-36 months. The thought of growing my own pineapple always makes me smile and giggle just a little bit. Now what am I supposed to do with all of this leftover pineapple? I see something sweet coming soon. While you’re waiting for me to make something yummy with the leftovers, go ahead and plant a pineapple. Be adventurous plant a pineapple. Hugs, Tickled Red *Please bear in mind that I am not a hortoculturist. Tagged as: Gardening, Pineapple, Tropical Fruit
7 Useful Genetic Experiments That Are Creepy As Hell Reviving Extinct Animals Bringing back prehistoric animals has been a trope in science fiction for a very, very long time. So far, none of these efforts have come to fruition. Scientists have been trying to clone the wooly mammoth for over 10 years, and despite continuous reassurance that we're on the brink of a major breakthrough, no one's pulled it off yet. Still, though. Most recently, a scientist announced his intention to reverse-engineer a dinosaur from a modern chicken by systematically removing DNA, because that makes nothing but sense. However, scientists have succeeded in reviving the genetic material of an extinct predator called the Tasmanian tiger, a nine-foot-long giant marsupial capable of hopping on its hind legs like a kangaroo and hiding its young in a pouch, presumably to launch them out as bloodthirsty living projectiles. Otherwise known as "the saddest Sean Connery-related moment of our childhood." "This is going to rock tits." At which point it joined the Uncanny X-Men.
The 20 Best Movie Drinking Games It's St Patrick's Day, and no doubt the pressure is on to head downtown for a few jars this evening (or, if you're a student, when doors open). For the budding film fanatic, though, that cuts into viewing time, so here's the ideal way to keep inebriates and cinephiles alike happy. We've compiled some of the best movie drinking games from the collective wisdom of web-based boozers, as well as adding a few on our own. Sci-fi, gangster flicks, comedies and thrillers, classics and modern hits are all catered for. All of these will get you wasted while doing the public service of keeping you off the streets. Please drink responsibly. The Shining Lazydork is the Wikipedia of movie drinking games, a dedicated resource with hundreds of titles available, including their take on The Shining. Choosing Stanley Kubrick's chiller feels wrong, somehow - after all, it's the tale of an alcoholic falling off the wagon and trying to murder his family. Drink Every Time: AND IF YOU REALLY WANT TO GET WASTED . . .
News: New Microscope Produces Dazzling 3D Movies of Live Cells High-speed imaging with the Bessel beam plane illumination microscope reveals the ever-changing surface of a HeLa cell, with long, thin projections called filopodia continually extending and retracting. Video: Laboratory of Eric Betzig/Janelia Farm A new microscope invented by scientists at Howard Hughes Medical Institute’s Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light—similar to that used in supermarket bar-code scanners—to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail. Liang Gao, Thomas Planchon and Eric Betzig display their new Bessel beam plane illumination microscope at HHMI’s Janelia Farm Research Campus. A major goal of biologists is to understand the rules that control molecular processes inside a cell. There's no other technique that comes close to imaging as long with such high spatial and temporal detail. Eric Betzig They then set out to image as fast as possible.

Computing speed doubles every two years. Two years after Artificial Intelligences reach human equivalence, their speed doubles. Six months - three months - 1.5 months ... Plug in the numbers for current computing speeds, the current doubling time, and an estimate for the raw processing power of the human brain, and the numbers match in: 2021. But personally, I'd like to do it sooner. 1: The End of History It began three and a half billion years ago in a pool of muck, when a molecule made a copy of itself and so became the ultimate ancestor of all earthly life. In less than thirty years, it will end.
Bacteria hijack an immune signaling system to live safely in our guts Our immune system operates under the basic premise that "self" is different from "non-self." Its primary function lies in distinguishing between these entities, leaving the former alone while attacking the latter. Yet we now know that our guts are home to populations of bacterial cells so vast that they outnumber our own cells, and that these microbiota are essential to our own survival. As a recent study in Nature Immunology notes, "An equilibrium is established between the microbiota and the immune system that is fundamental to intestinal homeostasis." How does the immune system achieve this equilibrium, neither overacting and attacking the symbiotic bacteria nor being lax and allowing pathogens to get through? Like many stories of immune regulation, this one is a tale of many interleukins (ILs). IL-22 is produced by the subset of T cells defined by their expression of IL-17, known as TH17 cells, as well as by innate lymphoid cells.
Leafcutter’s DIY Steel Can Hydrophone & Preamp. Step-by-step guide | leafcutterjohn.com Leafcutter’s DIY Steel Can Hydrophone & Preamp. Step-by-step guide *schematic link fixed!* *schematic link fixed!* Completed steel can hydrophone Hydrophones enable us to record underwater, this is reason enough to worship and adore them. If you don’t know what the hell I’m talking about right now have a look at these instructions on how to make the simplest possible contact mic It’s exactly the same principle when making a hydrophone except you get to go underwater. I decided to house the pre-amp in the same enclosure as piezo elements (to avoid noise entering the circuit). Two steel cans cut down to size After a few experiments, I found you can quite easily solder steel food cans together using a regular soldering iron and electrical solder. I used a small rotary cutting wheel on a dremel tool to cut nice neat slices of can. Piezo elements super-glued to lid and wired up I used a wire brush to rough up the surface of the can before super-gluing two piezo elements to the inside of the lid.
