Awesome Mark Rober

If you put a powerful fan on a boat and blew it at its sail, would the boat move? Engineer Mark Rober channels Mr. Wizard with a series of experiments and easy-to-understand explanations of this and six other perplexing physics questions. He also debunks a viral video along the way.

Mark Rober has been frustrating porch pirates and other thieves with his trick glitter bombs for a while now. To wrap up the series, he teamed up with a local news outlet in San Francisco to set up a bait car and backpack, covering thieves with glitter and fart spray and tracking the stolen goods to help identify the criminals behind the break-ins.

A little while back, Mark Rober engineered a tiny NERF gun using a compliant mechanism. The design has spawned numerous other builds, including this neat-looking blaster Matt Esltea made from wood. It’s not made from a single part like Rober’s NERF weapon, but it’s built with a similarly springy launching mechanism. It’s a beautiful build, but will it work?

It’s common knowledge that octopi are intelligent creatures. After he purchased an octopus from a pet store, engineer Mark Rober wanted to release the animal back into the ocean. Before he could do that, he built a challenging maze to confirm that Sashimi would be able to hunt for food after being hand-fed for most of her life.

We would say, “Don’t try this at home,” but most of us don’t have a cauldron of molten lava or a vat of acid lying around. Mark Rober’s video includes a series of experiments in which he and his pals tested the destructive abilities of lava, acid, and some wildcards. The video culminates in a challenge to see which could kill a car engine quicker.

Mark Rober and his pals made one of the largest NERF guns ever. This time, he went in the opposite direction, putting the popular toy through the shrink ray so many times it’s only visible with an atomic force microscope. After using a compliant mechanism to engineer a simplified version that can fire a dart, he worked with scientists to make NERF guns from DNA.

Hitting a flying baseball or wiffle ball takes practice, but you can do it with time. With a game against a team of professional wiffle ball players on the line, Mark Rober engineered a cheat to give him a chance. He started by studying the physics that enable curveballs and created mechanical balls that change trajectory as they approach the batter.

It’s easy to float a ping pong ball above a diagonal stream of air thanks to the Coandă effect. Mark Rober of Crunchlabs wanted to see what could be lifted with a stronger wind source than a blow dryer, so he subjected various household items to a high-pressure jet of compressed air.

Most DoorDash and GrubHub deliveries are made using gas-guzzling cars sitting in traffic. Zipline hopes to change that with drones that hover 400 feet up, then lower a small delivery unit to quietly and safely drop off small packages. Mark Rober explains the tech and how Zipline has been saving lives with their existing drones.

After embarrassing numerous porch pirates, engineer Mark Rober is back with the final and most ambitious iteration of his electromechanical glitter bomb. Version 5.0 is packed with autonomous glitter drones and even more fart spray to ruin any criminal’s day. He also built a stripped-down version for car break-ins.

To celebrate the launch of CrunchLabs, engineer Mark Rober endeavored to set up the world’s longest Hot Wheels track. At over a half-mile long, the track takes advantage of the warehouse space and has stacked switchbacks with Hot Wheels Boosters to keep the cars moving. We’d love to see the FPV footage of the full ride.

For his latest experiment, rocket scientist and entertainer Mark Rober teamed up with Joe Barnard of BPS Space to launch an egg into space to see if they could catch it safely a mattress when it dropped back to earth. But the project proved far more challenging than they thought and required huge amounts of trial and error.

Mark Rober and his backyard buddies are back. Not only are the obstacles more difficult than ever, but now it’s a squirrel vs. squirrel, Olympic-style competition. Who will take home the nutty grand prize? Will it be Phat Gus, Augustine, Rick, or Marty? Hit play and find out.

Mark Rober likes to use his engineering skills to help the little guy get a fair shake. After showing us how to improve our chances at carnival games, he built a series of portable devices that help him cheat and score the most at skill-based arcade games, and also shows us which ones are complete scams.

You know those pin art toys that take an impression of your hand or face? I Like to Make Stuff built a super-sized version of the plaything for their Maker Alliance pal Mark Rober to put in his new offices. He used large sheets of PVC, insulation foam, and 1000 PEX tubes to create the structure and its pins.

Engineer and all-around good guy Mark Rober stopped by First We Feast’s studio to take on the spiciest of wings. After chugging down a dose of Pepto Bismol, he talks about his new Discovery show Revengineers, his experiences working at NASA, his best builds, and how to always win a coin toss.

Engineer Mark Rober is known for pulling off some of the biggest experiments, pranks, and fun things on the internet. Now, he’s built an awesome maker’s space, lab, and play place with hidden entrances, a giant foam pit, and a bathroom that alerts everyone if you don’t wash your hands. It’s also the HQ for Crunch Labs.

Mark Rober needs to add “Citizen Hero” to his resume. After taking down porch pirates, he got revenge on four notorious scam call centers by disrupting them with stink bombs, glitter bombs, cockroach bombs, and more. It all came together with the help of CCTV hacker Jim Browning and Trilogy Media on the ground.

Engineer Mark Rober takes a look at a very special piano that can transform speech into music. Known as Chopstix, the Edelweiss player piano was modified so it can play all of its keys simultaneously. It feeds on a steady diet of MIDI files which it can play at incredibly fast speeds. It can even perform Rush E.

After Jimmy Kimmel told Mark Rober about his dream of having the most powerful t-shirt cannon in the world, the Mark wanted to oblige his friend. He had a little extra help from wunderkind Anthony Hartman to design and engineer the big gun. Sadly, the stadium’s lawyers put the kibosh on firing the most powerful version.

Engineer Mark Rober is back with the 4th-generation version of his karma-delivering glitter bomb package. For 2021, the package for porch pirates is filled with new surprises, including a self-launching box lid, a car horn, and 20% more fart spray.

The sheer amount of trash floating in our oceans and waterways is staggering. To help TeamSeas reach its goal of removing 30 million pounds of trash by January 1, 2022, Mark Rober challenged Mr. Beast to see if an army of humans or trash-gobbling robot boat could remove more trash in the same amount of time.

Engineer Mark Rober keeps his promise for bigger and more spectacular experiments by building the tallest ever stream of elephant toothpaste, a foamy mess created by mixing hydrogen peroxide, soap, and potassium iodide. The trick to sending the stream sky-high was bolting the giant steel flask to a concrete pad.
