Makerbot Is Letting You 3D Print With Metal, Limestone, and Wood

Makerbot—perhaps the most consumer-friendly of 3D printer manufacturers—is about to go a long way toward turning the tech into something consumers can actually use. Starting late this year, MakerBot is going to let you 3D print with a range of new materials, including composites of limestone, iron, and wood. » 1/06/15 10:40am 1/06/15 10:40am

Video: Turning soda cans into liquid metal looks so fun

I'm not going to give my aluminum cans to recycling centers anymore. Instead, I'm going to melt them down to liquid metal and create awesome metal objects with them. All I need is a hair dryer and some charcoal to create this awesome mini metal foundry. It turns about 40 cans into a pound of aluminum. » 12/31/14 9:02pm 12/31/14 9:02pm

These fire hot giant chains look like they're being made in Mordor

I'm halfway certain that there is sorcery from Middle Earth involved in building this humungous chain. But it's pure human ingenuity. The chain is meant to be used on Shell's Prelude project (a floating liquefied natural gas platform) which is basically some ginormous platform that's permanently moored offshore. » 12/24/14 11:11pm 12/24/14 11:11pm

Making a screw flush with the surface is like creating invisibility

When a screw sticks out on metal or isn't perfectly flush with the surface, an angel in heaven loses an eyeball. Or something like that. But fret not eyeballs of angels in heaven, people of Earth can make a screw completely flush. It's a lot of filing and sanding and hammering but eventually the screw disappears. » 12/16/14 9:11pm 12/16/14 9:11pm

Making metal framed eyeglasses looks like a fun lab experiment

I'm pretty sure the only time I prefer the look and feel of plastic over metal is with the frames of glasses. I just like acetate frames more. But! The process of making metal frames, like these pair of metal MYKITA glasses, is so interesting that I may need to get a pair. It's like watching scientists in a lab… » 11/24/14 9:37pm 11/24/14 9:37pm

Seeing an old anvil get restored is surprisingly enjoyable

Wow. This is actually really cool. Jimmy DiResta found an old anvil from an antique store and restored it to its previous glory. The finished restored anvil looks fantastic but it's the entire process that's got me slack jawed. All the sparkles and whirring and refining and polishing makes restoring look like a form… » 10/09/14 12:16am 10/09/14 12:16am

Foolish Scientists Have Just Created Shape-Shifting Metal

Most movies are works of fiction, but the plots are based on real-world ideas. Including, apparently, the nightmarish future put forth in Terminator 2. A team of researchers from North Carolina State University decided the world would be a better place with terrifying shape-shifting T-1000s, and so have developed a… » 9/22/14 9:07am 9/22/14 9:07am

Why Beer Isn't Sold in Plastic Bottles

Plastic as a material has pretty much changed the way we live our lives- it's cheap, can be moulded into practically any shape and is, for the most the part, easily recyclable (when people bother to). So why is it that we still use glass bottles and cans to store our beer in? Is it to do with aesthetics? Taste? Or is… » 9/01/14 10:00am 9/01/14 10:00am

A lightsaber katana is the closest we'll get to Star Wars in real life

I'm still holding out hope for light sabers in the future but with our world's technological limitations and silly allocation of resources, the most beautiful deadly sword-type weapon we can create without lasers might be this mashup of a lightsaber and katana made by Man At Arms: Reforged. » 8/11/14 9:28pm 8/11/14 9:28pm

Fun guy spins his head like a metal rock star while doing construction

It doesn't get any more metal than this. This headbanger filmed a video of himself spinning his head and making his hair whip in dizzying circles while working construction jobs. It's so hardcore badass but also incredibly goofy and fun all at the same time. He rocks out with his caulk out. » 7/02/14 11:09pm 7/02/14 11:09pm

Wire magically untangles itself in water

Nitinol wire, a metal alloy made from nickel and titanium, basically has magic properties that lets it remember its 'original' shape. You can bend it over and over, twist it up, bunch it together and confuse the heck out of it however much you want but once you throw it in hot water, it'll snap back to its original… » 6/10/14 11:14pm 6/10/14 11:14pm

Mushrooms Can Mine the Gold From Your Old Cellphones

Crack open your dumb old phone, and you'll find lots of circuits and no lack of precious metals. "In 100,000 cell phones, it's estimated that there is 2.4 kilograms of gold, more than 900 kilograms of copper, 25 kilograms of silver, and more," according to Motherboard. Could a safer and and cheaper method of… » 4/14/14 7:00pm 4/14/14 7:00pm
