Awesome Mark Rober

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.

Setting up dominoes can be time-consuming and requires a steady hand. We’ve seen robots that can stand one domino at a time. Mark Rober and his engineering pals presents DOM – a custom-built robot that can set up 300 dominoes at a time. The robot arm and Hot Wheels track loading system is equally awesome.

A while back, engineer Mark Rober built an obstacle course to try and keep squirrels from getting to his birdseed. Ultimately, the smart squirrels figured it out, so he decided to up his game with a far more complicated maze that’s even trickier to navigate. Will the squirrels get their claws on Mark’s nuts again?

After two two prior efforts to get back at package thieves, engineer Mark Rober kicks things up another notch. His latest Glitter Bomb is the most diabolical “gift” yet, adding the nasty glue from mouse traps, 4x the fart spray, eau de skunk, a police light effect, and a mechanism that makes it harder to shut off.

After an earlier experiment with trying to get sharks to swarm into human blood, Engineer Mark Rober teamed up with Discovery’s Shark Week to build a single-person shark cage, and headed into the waters of the Bahamas to see if he could get a feeding frenzy going around him using fish blood instead.

We’ve all heard the advice to wash our hands, avoid touching our faces, and clean our smartphones if we want to avoid catching and spreading coronavirus or other bugs. Mark Rober uses some UV-reactive powder to demonstrate why that’s so important, and shows just how much stuff we touch and leave our germs on.

Mark Rober typically uses his engineering skills to solve complex problems or to exact justice, but this time, he’s just having a good time making a mess. He teamed up with the guys from How Ridiculous to see what would happen when you drop a car onto the world’s strongest trampoline. Check out the aussies’ video here.

After building an ingenious device to befuddle porch package thieves, Mark Rober is back with a new and improved version. Like the original, it shoots video of the thief, fires off glitter and fart bombs, but with a little help from his friend Sean Hodgins and Home Alone star Macaulay Culkin, this version is better in every way.

Smart guys Mark Rober and James Bruton show us how to game the system with engineering know-how. They recently collaborated on a special bowling ball that can consistently bowl strikes by simply leaning in the direction you want it to go after you release it down the alley.

The idea of filling a swimming pool with gelatin seems simple enough, but as engineer Mark Rober explains, it’s way more complicated than you might think. Leave it to a rocket scientist to figure out how to boil and then refrigerate an entire pool filled with 15 tons of Jello.

Mark Rober and his friends worked with Destin of Smarter Every Day to add rockets to a golf club. The resulting contraption can consistently propel a golf ball to 150mph. It’s so powerful, they couldn’t find the balls it hit. They also made a weaker handheld version.

After one of his packages got stolen, Mark Rober and his friend spent 6 months making a smart glitter bomb. Not only does it spew a ton of glitter, it also sprays fart spray and best of all records the whole thing. Here it is punishing evildoers.

Mark Rober wanted to demonstrate how horns work, so he built what’s quite possibly the largest air horn in the world. After explaining how horns amplify sound, he tested the horn in a remote area. It carried sound clearly from as far away as 2.5mi.

A while back, a video made the rounds showing what was supposedly a flying phone case. We figured it was fake, but as Mark Rober and Captain Disillusion point out, it also scammed people out of cash. Keep an eye on Peter Sripol’s channel for his WORKING version.

Mark Rober spoke with game design professor Dr. Scott Nicholson to learn 10 tips that can help you beat any escape room. The tips include not overthinking clues, knowing where to search, and having someone to organize the rest of the group.

Mark Rober has built a lot of fun and fascinating gadgets. He explains his process with his latest build – a rock skipping robot. Through rigorous research and testing, he was able not only to build the robot but to learn how rock skipping works as well.

VW turned up to Pike’s Peak this year and broke the course record with their I.D. R EV. Prior to the race, the automaker challenged Mark Rober and William Osman to collect a little extra energy for their their supercar. We like to think the citrus power made the difference.

Engineer and inventor Mark Rober recently lost his wallet, and he never got it back. But was that an isolated incident, or are there still honest people in America’s cities? Mark decided to find out by dropping 200 wallets in 20 cities to see to gather some data on human behavior.

After using science and math to point out all the ways in which the decks are stacked against you at carnival games, engineer Mark Rober is back to show us how coin-operated arcade prize games aren’t any better.

A fluidized bed is a mixture of a solid and a fluid that behaves like a fluid. To show us how it works, Mark Rober mixed sand with bursts of air – when the air is piped in, the sand behaves like it’s a fluid. Just for kicks, he also made a larger bed using a discarded hot tub.

Not satisfied with having the world’s largest NERF gun, Mark Rober and his friends spent a total of 6 months making the world’s largest Super Soaker. The 7ft long gun shoots water at up to 272mph using pressurized nitrogen.

Mark Rober teamed up with Eclectical Engineering to create this awesomely unwieldy weapon which fires huge foam darts, made from pool noodles and toilet plungers. Thanks to compressed air, it can fire darts at speeds up to 40 mph. Check out the gunpowder upgrade.
