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.
THE BEST Mark Rober
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.
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.
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.
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.
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.
