An excerpt from Science Channel’s How It’s Made which takes us inside of a factory that churns out millions of paintballs every year. It turns out these painful projectiles are basically made from the same stuff that gummy bears are made of – though we bet they don’t taste as good.
After creating a mix of chilled acetone and water that was both slushy and flammable, The King of Random tried to make fiery snowballs using a similar technique. After a few false starts, he succeeded with gasoline-soaked snowballs. Kids, don’t try this at home.
Voltera’s machine lets you print two layer circuit boards right on your desktop. Its plotter lays down layers of silver-based conductive ink, making circuit prototyping and experimentation crazy simple. it can even prep, heat, and reflow solder for surface-mounted components.
Maker Gustav Evertsson paid tribute to the 2018 Winter Olympics with a neat build. He created a series of motorized blades which he loaded up with steel wool and set ablaze. The resulting persistence of vision illusion reveals a fiery version of the iconic 5-ring Olympic logo.
A look at the Rudolf Grauer BK-1500 – a machine designed to crank out up to 1500 paper clips per minute in a variety of shapes by bending stiff strands of wire. The voiceover is in German, but that just makes the engineering seem even more serious and impressive.
Jackman Works shows us how he transforms old cargo pallets into sweet drink coasters by sanding, stacking, cutting, and laminating strips of their varied wooden slats into grid patterns. Show your appreciation for his craftsmanship, and buy a set of the coasters here.
Engineer BrunS takes his metalworking skills to the world of Fallout, meticuously crafting this bronze, duralumin, brass, ebonite, and luminofor model of the Red Rocket from the wasteland’s #1 diesel fusion filling stations. Available from his Etsy shop for about $500.
Laser engravers use powerful laser beams to burn designs into wood and other materials. But when Make Anything’s flatbed engraver broke, he decided to take its laser head and turn it into a handheld writing instrument. It’s not the safest thing on Earth, but it is cool.
After building himself an airplane, Peter Sripol decided to make himself something a little less ambitious, but just as fun – a tricked-out sled that can glide across the snow thanks to an airplane propeller on the back. It’s not exactly fast, but it lets him go sledding without a hill.
This wouldn’t be the first time we saw a machine gun that fires rubber bands, but this time out, we’ve got The Q showing us step-by-step how he built his from cardboard, wood, string, hot glue, and popsicle sticks. If you’d rather not DIY, you can buy a wood one here.
Love you some Pringles? Just remember that next time you chow down on one of those neatly-stacked, perfect potato chips, you’re actually eating a delicious pressed, formed, and precision-cut mush of potato flakes. They’re like the Chicken McNuggets of chips.
Adam Fieldson of WhipWorks makes beautiful bull whips by weaving nylon paracord. Here, he walks us through the painstaking process of making one of his whips – a gift he presented to Tested and Mythbusters star Adam Savage. You can purchase his work in his Etsy shop.
Not every knife has to have a single continuous edge, does it? Watch as blademaker Miller Knives cuts out and sculpts a truly unusual knife with a crazy staggered edge. It looks like something out of a video game or a comic book, and also like it would be really deadly.
Wooden threaded rods are typically used for things like broom handles or decorative items. Toolify shows us how to make a neat variant of a pantograph machine which can be used for routing threaded wood rods at different thread densities. If you need a nut to go with…
BrainfooTV shows us how to make nifty little rockets using ordinary household items like aluminum foil and strike-anywhere matches. They fire as far as 60 feet, and are surprisingly stable and accurate. The tailfins aren’t required, but they do make them look cooler.
Tony Fisher knows a thing or two about making Rubik’s Cubes. After all, he’s the guy behind the world’s largest working cube, and has also built all kinds of complex variants. Here, he shows off a fully-functional puzzle that he made using ice. Hopefully, he’ll work out a color version.
Artist and goofball Bobby Duke laminates together a few hunk of bass wood and carves them into the shape of a mug. But his craft project doesn’t end there, as he eventually transforms his creation into an awesome sculpture with the help of some colored pencils.
Maker W&M walks us through the process of turning a couple of muffin tins into a miniature concrete mixer, complete with a motorized stirrer. Though in this case, its purpose is to smoothly blend instant coffee with water. Probably would make a good hot cocoa too.
