Mark Rober, who we last saw engineering a dart board that guaranteed a bullseye with every throw, has just built what every car-loving kid always dreamed of: an epic Hot Wheels track that has tiny vehicles racing between floors, through swimming pools, and jumping over giant explosions.

Video: A night at a local pub isn't complete without a few rounds of darts, but as your blood-alcohol level rises, your ability to hit the bullseye greatly diminishes. Unless you're playing with Mark Rober's motion-tracking dart board that automatically repositions itself so you're guaranteed to hit the bullseye every time.
Video: Would you sink or float if you were tossed into a gigantic vat of squishy gelatinous spheres? Mark Rober, one of the Backyard Scientists, decided the only way to definitively answer the question that few have ever asked was to fill an entire pool with 25 million of the tiny spheres, and dive in.
If you've ever driven a car that's parked outside in winter, you'll know it's frigid as hell inside your car and the windshield can be totally opaque from all the foggy arse frost. Not cool. How do you get rid of it? Hit the defrost button right? That's not all. The always inquisitive Mark Rober tested out every combination on how to defrost your windshield and came up with a way that is twice as fast as other methods. That means you'll get a clear windshield in half the time.
Every child and every adult who wants to be a child again loves a good Nerf gun. They're fun to shoot, whether you're playing in your yard or across cubicles, and they're fun to be shot at with, because Nerf guns are mostly harmless. Well, the game done changed. Mark Rober has invented the world's biggest Nerf gun and it is beyond awesomely badass while being totally hilarious.
Video: YouTube scientist Mark Rober and molten metal obsessive BackyardScientist teamed up to answer a simple question: is a grenade deadlier on land or under water? But in order to answer that, we need to understand exactly what a grenade does.
After watching this video I feel like the best microwave I've ever used sucked very badly. What you see here is a concept for the Heat Map Microwave, which would have a built-in IR camera on top and a screen on the front, effectively allowing you to see exactly when your food has been heated all the way through. Get this thing in my kitchen right now.
Proving that sometimes all it takes is a popular YouTube video to kickstart a successful business, Mark Rober, the guy who made the gaping hole in your gut costume using two iPads a few years ago, is back with even more easy but impressive costume ideas. And that includes a line of Halloween masks that come to life with nothing but a smartphone running a free app.
Thermal cameras were once expensive and bulky hunks of equipment that very few people could get their hands on. No longer. With FLIR's new iPhone case thermal imaging cameras are now both affordable and incredibly discreet, which means that evil-doers can use it to see the thermal signature your fingers leave on a keypad and steal your ATM PIN. Here's a very simple way to thwart that.
Back in May, our friend and ex-NASA JPL engineer Mark Rober, figured out a way to shoot "bullet time" videos on the cheap, with a ceiling fan, a pair of torches and a GoPro. Pretty damn creative, but the rig had its limitations. So Mark set out to find a way to create a similar setup, this time using a high-end Phantom camera. Thank goodness.
ago, NASA engineer Mark Rober blew YouTube's mind with a video of his Halloween costume: a hole in his chest. Or at least it looked like a hole in his chest. In fact, it was an optical illusion made possible by two iPads, a little duct tape and a lot of ingenuity. Well, you won't believe what he's been up to since then.
