SmarterEveryDay made a transparent potato cannon that can be ignited from the back or from the middle of its combustion chamber. He then captured it in action at 25,000fps to teach us about explosions and rarefaction. And to make the best Audible commercial.
Awesome Slow Motion
The Backyard Scientist continues his literally and figuratively sloppy experiments by “testing” oobleck (cornstarch mixed with water). Like ketchup, quicksand and silly putty, oobleck is a Non-Newtonian fluid. It flows like a liquid but behaves differently when force is applied to it.
BBC Earth Unplugged turns its macro lens on the house fly to show just how good they are at detecting impending doom, with their omnidirectional vision and fast reaction time. It’s fascinating footage, but we’re pretty sure they could have hit the fly if they tried harder.
We’ve seen lots of awesome yo-yo tricks over the years, but videographer Darren Dyk gives us a newfound appreciation for the artistry and talent that goes into these tricks by capturing master yo-yo throwers JT Nickel and Paul Dang with his Phantom slow motion camera.
Dan of The Slow Mo Guys acceded to fan suggestions (and the lure of YouTube fame and fortune) and triggered a mouse trap with his tongue in front of their Phantom camera. While the human tongue is indeed strong, it’s definitely not numb. Man that was nasty.
If you’ve ever been clocked on the head by a golf ball, you’d be certain they’re hard as a rock. But they’re actually quite pliable. Here’s slow-mo footage of a golf ball as it hits a steel wall at 150mph. While it’s likely it was a practice ball, a regular ball still flexes quite a bit.
Ladies and gentlemen, the Los Angeles Lakers. Nah, MythBusters tested if a tank car can implode because of a vacuum. After two failed attempts, they succeeded by using a damaged and old car. The funny part? They could’ve confirmed the myth with a YouTube search.
The Slow Mo Guys loaded up a drill bit with several colors of wet paint, then captured the ensuing spatter with their high-speed camera at up to 2500fps. The spiraling paint drops are cool, and they could probably sell the artwork they created at a fancy gallery now.
