Robotic hand made of wires is flexible enough to rotate meditation balls
Baoding balls are two metal balls that are rotated over and over again in one hand for meditation, exercise or rehab purposes. A lot of dexterity and focus and strength is necessary to pull of the rotation. Not everyone can do it! This robotic arm controlled by wires can though. Look at those fake flexible fingers…
Watch white blood cells swarm and attack a parasite
The human body is such a magnificent thing. Just check out this video that shows how our immune system works. When a parasite finds its way inside a place where it clearly shouldn't be, white blood cells immediately start rushing to the rescue. It only takes a few seconds for the parasite to get swallowed.
Goddesses materializing out of nowhere
Oliver Oettli says that he usually doesn't do stuff like his Power Winds photo series but these photos became his most well known project. And rightly so. They feel magical, as if these women were supernatural beings. No digital tricks here: Photoshop was only used to adjust color and contrast.
Spectacular live fire photos taken by an F-18 weapons trainer officer
Lieutenant Chris Nigus sent us these series of spectacular photos taken while flying on missions during the last couple of years of his deployment in Japan. Above you can see him flying low level in Japan's Orange Route. Some of them show weapons firing from his F/A-18E Super Hornet.
The only fun fact about Apollo 13's dramatic failure is this invoice
I didn't know about this fun factoid: On April, 1970, the Grumman Aerospace Corporation—manufacturers of the Lunar Module—sent a $312,421.24 bill to North American Rockwell—who made the service module that malfunctioned in the Apollo 13 mission—for towing services. Why, you ask? Here's the story.
Mold is surprisingly beautiful when you look at it up close
Russian photographer Nick Lariontsev made this cool time-lapse using macro lens to show how mold grows from up close. At this zoom level, something that normally disgust us transforms into a beautiful alien universe full of life.
Did this mad Russian really shoot his friend's head to test a helmet?
This insane video shows a Russian guy shooting a pistol at his friend's head to test the quality of the K6-3—a titanium helmet with bullet-proof glass used by Russian special forces. Some commenters think this may be fake. Many think it's real. What do you think?
Machine turns solid metal into an impeller in utterly satisfying video
I could spend hours watching this milling machine—SolidCAM's iMachining and simultaneous 5-Axis Milling—transform a solid metal cylinder into a fully functional impeller.
Watching 1000 marbles run at the same time is oddly relaxing
Jelle Bakker's hobby is making huge marble runs and rolling ball sculptures. One of his creations is the "Marblelanche": An epic marble machine with obstacle tracks that fits 1000 marbles.
