Mark Rober is an engineer and hugely popular YouTuber who covers science, technology… and backyard squirrel sports, apparently. Mark has made a number of videos where he builds various obstacles and challenges for the squirrels in his backyard.

In this video, he puts all of this together into a grand challenge. — Read the rest

Professional glitterbomber Mark Rober did some detective work to track down a massive U.S.-India scammer ring. He explains how this kind of scammer preys on people and tricks them into sending over $10,000 in cash.

YouTuber Mark Rober got some powder with the delightful name Glo Germ, which glows when exposed to ultraviolet light. He then went to a 3rd grade classroom and put some of the powder on the hand of the teacher (the students were not told about the experiment). — Read the rest

Mark Rober is bad at darts, but he still gets perfect scores, because he's good at engineering.

I fulfilled a 3 year long dream to create a dartboard where you get a bullseye every time thanks to some engineering. Basically, you throw a dart and then a Vicon motion capture system tracks the dart in the air.

We've all seen the videos of thieves shamelessly stealing packages off of people's porches. Now someone is fighting back.

Skipping stones takes a little practice and finesse, so Mark Rober enlisted his extended family to help build the perfect rock-skipping robot. Their creation, named Skippa, ended up helping humans learn, too.

Even what's billed as the world's largest lemon battery can only generate enough juice to charge a small battery cell, so Mark Rober tries a few other fun power generators with a bunch of young scientists-to-be.

For the first time in over 60 years, Easter and April Fools' Day are on the same day, creating the rare EasterFools' Day holiday.

To celebrate, former NASA-JPL engineer/current science YouTube star Mark Rober (previously) went on Jimmy Kimmel Live to demonstrate some easy pranks for this rare double holiday. — Read the rest

This ain't Mark Roberts' first rodeo.

The British nudist who hopped onto an Olympic ice rink at PyeongChang in a pink tutu and a monkey-faced codpiece (strategically covering his junk, of course) has a long history of streaking. For 25 years now, Roberts has run bare (partially or completely) at hundreds of international sport events, including Super Bowls. — Read the rest

Science YouTuber (and former NASA engineer) Mark Rober explains how when you add air "in the just the right way" to sand, it "basically becomes a liquified soup." It sure does!

Watch and learn.

Former NASA-JPL engineer Mark Rober explores carnival scam science and has a few tips on how to win, at least occasionally.

Former NASA engineer Mark Rober has invented a fancy in-dash car horn with three custom settings. The first one is sort of a swift and friendly 'toot, toot' for when your regular horn is too aggressive. The other two? Well, I won't spoil it but one is even friendlier than the first and the other is meant to get some real attention in "extreme situations." — Read the rest

Mark Rober teamed up with The Backyard Scientist to see what happens when you fill a pool with 25 million water balls then try to jump in.

You'd think hitting the defrost button in your car on a chilly morning would be the quickest way to defrost your windshield. But not necessarily so, according to ex-Nasa engineer Mark Rober, who has come up with a way to defrost car windows in half the normal time. — Read the rest

What a beautiful video by Mark Rober, of NASA's Jet Propulsion Laboratory: "I was able to work on NASA JPL's Curiosity Mars Rover for 7 years. This video is an attempt to capture what it felt like to have 7 years of your life vindicated in the 7 minute landing. — Read the rest

On this week's edition of the PBS television program "California Connected," I join host Lisa McRee with guests Beth Givens, Privacy Rights Clearinghouse, State Senator Debra Bowen, and Mark Roberti, RFID Journal

to debate consumer privacy issues related to radio frequency ID tag (RFID) technology. — Read the rest

I wrote a story for The Thackery T. Lambshead Guide to Eccentric and Discredited Diseases, a forthcoming anthology of funny, faux-Victorian illnesses edited by Jeff VanderMeer and Mark Roberts. Other contributors include Michael Moorcock, Neil Gaiman and Elliot Fintushel. Every copy is signed by all contributors, and I just read through a galley and found myself laughing aloud all the way through. — Read the rest

Leonard Peltier has spent the last 48 of his 75 years in prison following a controversial trial that found him guilty of murdering two FBI agents.

In 1975, the two agents arrived at a home on the Pine Ridge reservation in South Dakota in plain clothes and an unmarked car. — Read the rest

2015's breathless Fury Road felt like an arcade game, catapulting viewers from spring launcher into the rugged, dusty wasteland of war rig bumpers and war boy multipliers. It's fantastic, made entirely of orange dust, style and split-second cuts. Furiosa's more of a video game with extended cutscenes and beleagured achievements to unlock. — Read the rest

When the Los Angeles Sheriff's Department makes headlines, it's never because of the great job they're doing. Earlier this week, we saw a deputy get busted for smuggling drugs into a jail as part of a larger operation to investigate "Operation Safe Jails". — Read the rest
