A while back, The Hacksmith built an impressive replica of Thanos’ dual-ended sword, but it was quite difficult to wield. Now, they’ve put the thing to good use, securely connecting the weapon to a motor, building a cinder block shield around it, and turning it into the world’s largest (and most terrifying) blender.
These fun-looking marble tracks mount on magnetic surfaces like some whiteboard and fridges, letting you create Line Rider-style courses that take full advantage of gravity. Available tricks will include a spinner, bell, launcher, catapult, a motorized lift and more. Launching soon on Kickstarter.
Flat pack model maker Ugears 48-piece kit is one of their easier builds, yet it’s simply fascinating to watch. The mechanical contraption converts air pressure to movement, which in turn spins a pointer which acts as a sort of decision maker for the next task for you to work on.
As long as we’re not carrying a heavy suitcase, we generally take the stairs when given a choice. But for those times when you feel like giving your legs a break, the escalator is quite the invention. Jared Owen provides an animated explanation of the inner workings of this engineering marvel that dates back to the mid-19th century.
The Brick Wall has made some pretty nifty LEGO Technic machines over the years. This one continues his tradition of making them functional by including a pair of serrated blades which can rip through wood (or carrots). We love watching the grippy robot arms moving the pieces around.
It’s a requisite stop for every kid with change in their pocket. But have you ever wondered how dropping a coin into a gumball machine makes it dispense a chewy treat? Animator and explainer of things Jared Owen gives us a detailed breakdown of its mechanism.
In this fun video from Driving Line and Nitto Tire, they set up a Rube Goldberg-style chain reaction machine that eventually triggers some tire-smoking donuts by driver Ryan Tuerck. Along the way, there’s some paintball action, and a nasty looking knife-wielding drone, which thankfully didn’t slash any of the tires – or people.
K’nex fanatic Austin “Austron” Grainger shows off his latest build, an enormous ball machine made from over 115,000 pieces and more than 850 feet of track. It’s installed in the lobby of The Works Museum in Bloomington, Minnesota. It’s not quite as big as his record-breaking machine, but it’s the largest one that’s currently standing.
It took the Brick Experiment Channel quite a bit of work to put together this over-the-top LEGO creation, but what they ended up with was a crazy wheeled train of sorts, driven by a total of 100 wheels, 50 axles, 11 motors, and 4 battery boxes. It’s not the most reliable or agile ride, though.
Claw machines look like fun until you realize that they’re all rigged to keep you from getting the good stuff. Perhaps that’s why this dad decided to build his daughter Clara a very special claw machine for her birthday – one where the little girl IS the claw, and can grab whatever she can as a winch dangles her over the prize pit.
The LEGO Technic Control+ app lets you remotely control motors and other components using your phone. To prove its muscle, LEGO and Sariel’s Workshop teamed up to see if they could use it to control a real Liebherr 9800 excavator using only the parts from the Technic version. Behind-the-scenes video here.
This nearly 9-minute long chain reaction contraption from Sprice Machines and his pals features a hypnotic, yet needlessly complicated series of ball bearings, dominoes, blow dryers, and other random household objects work in concert to kick off the ultimate Rube Goldberg pool party.
We always assumed that the way they got seeds out of pumpkins was to scoop out the meat for things like canned pumpkin, then separate out the seeds. But from the looks of this video, pumpkins are smashed by machine right out of the patch, simply to extract the seeds. The process seems wasteful, but it’s still interesting to watch.
Engineers from ETH Zurich and the CERBERUS team worked together to create ANYmal, an autonomous robot which has wheels at the ends of its legs, making it capable of moving quickly, and negotiating over difficult terrain. Its moves kind of remind us of the wheelers in Return to Oz, but not as creepy.
If there’s one thing you can count on Burning Man for besides sand in every orifice of your body, it’s crazy machines. Among the weird and wonderful creations on display during the desert event last year was Zenichi Works’ Playa Crawler, a crazy chair with motorized Strandbeest style legs to move it along the ground.
We always thought that round candies were made using molds, but it turns out some of them are made by spin-carving spheres from a rod of sugar, like the ones shown in this video from candy machinery maker Loynds. We want to see a Bingo ball picker that works this way.
Artist Felix Vorreiter’s unusual timepiece uses a single, long piece of string that feed through a series of pulleys. The rope is marked with dots which align to display the current time. The current clock only has 120 minutes of string, as it would take about 4000ft to cover a full day.
A while back, Tom Stanton built a cool working trebuchet, but even though it was much smaller than the ones used in battle, it still wasn’t exactly portable. So, Tom set about building a pint-size version that can be used like a slingshot. We’re thinking it would be perfect for flinging wadded up paper at officemates.
In order to safely tear down the defunct Mülheim-Kärlich nuclear power plant, demolition crews installed a remote-controlled excavator machine at its top, which gradually nibbled away until its height was lowered from 531 feet to half its height. The remaining structure was brought down by breaking its supports.
It may not play music like Wintergatan’s marble-powered musical instrument, but we still enjoyed listening to the soothing sounds and watching the hypnotic movements of this wooden marble machine, which serves as an example of the modules you can buy from its creator.
Next time you go to the deli and it takes them 5 minutes to slice your meat, ask them to replace their machine with the TEXTOR TS700-UB. This industrial slicer spins up to 2000 rpm, cranking through pepperoni, bacon, and other meats, and neatly stacking them in the process.
Mr Machines compiled this footage of high-power demolition machinery as it rips apart industrial equipment for scrap. The part where it tears up the red truck like a dog with a chew toy is especially impressive, as is the bit where one cuts through steel beams like snapping twigs.
The Titans of CNC: Academy rightfully brag about their electronic machining equipment and skills by transforming a hefty 218 pound billet of aerospace grade titanium into a stunning sculpture of a lion’s head. In the end, they milled away over 100 pounds of material to reveal the metal king of the jungle.
After building a LEGO Technic machine that could bale hay back in 2017, The Brick Wall decided it was time to build a version that could create squared-off bales. The new machine offers impressive engineering, and is accompanied by a wagon for stacking and transporting bales.
As part of a campaign for Starbucks, Adam Savage was asked to help build excitement for their Nitro Cold Brew coffee. Naturally, Adam couldn’t resist doing something overly dramatic, and built a liquid nitrogen-powered engine for delivering a sweet cream topper. Disclaimer: This is not how Starbucks makes theirs.
This ridiculously complicated Rube Goldberg machine from DaksDominos uses dozens of ping pong balls, Hot Wheels tracks, string, dominoes, toilet paper rolls, plastic cups, glass bottles, and popsicle sticks to perform a simple task – dispensing a length of Scotch tape.
