Ferrofluid Sculpture

I just learned about Ferrofluid today. It can do some amazing things, like this video shows. After the jump is a second video explaining HOW ferrofluid works.

From the YouTube descriptioin:

A steel sculpture with changing magnetisation is coated with ferrofluid.
The fluid is pulled in the direction of increasing flux density and forms peaks, which become smaller in higher flux density. At an accumulation of fluid at ridges, the flux density at the surface decreases. The flow and the distribution of the fluid can be observed at several characteristic locations…

Bottoms Up Beer – Magical Beer Dispenser Fills Cups from the Bottom

[youtube]http://www.youtube.com/watch?v=wiu_IX14wLI&feature=player_embedded[/youtube]

This machine is somehow able to fill plastic beer cups by pouring beer up from underneath. Is it magic, is it science, or are you just really really drunk?  As it turns out, it’s science, although you may also be really really drunk.

Is The Sun About To Change Our Lives Again?

We, and by “we” I mean all life on Planet Earth, owe our very existence to the Sun. It’s nothing more than a typical star, really, but without it, this planet would be as barren as the day is long. (CG: Your home for old-timey phrases.) With that in mind, here’s what could become a pretty important story as we move forward…

Ultimate See-Through Speakers

Ultimate See-Through Speakers

Ferguson Hill’s transparent speakers

Check out Ferguson Hill’s transparent designed speakers. As you can plainly see, the FH001 is a horn speaker made of clear acrylic. Horns are among the oldest speaker designs because they are incredibly efficient, and they also extend the low-frequency range of the driver. As a result, the FH001 boasts an efficiency of 100dB/W/m and needs only 3 to 50 watts of amp power, making it ideal for tube-based power amps so beloved by many audiophiles. And its frequency range is an astounding 150Hz-20kHz (±5dB) with no crossover. (Pics)

Special ‘Thinking Cap’ to Unlock Our Inner Genius

 Special ‘Thinking Cap’ to Unlock Our Inner Genius

There is a theory that the spark of genius lurks hidden within all of us.Now scientists are developing a ‘thinking cap’ that could turn that theory into practice and unlock the amazing potential of the human brain. The device uses tiny magnetic pulses to change the way the brain works and has produced remarkable results in tests.

World’s Most Powerful Magnet Being Built In Florida

World’s Most Powerful Magnet Being Built In Florida

Your fridge magnets suck

Multiply the magnetic field strength of a refrigerator magnet by 2 million and you’ll be in the ballpark of the strength of the magnet that researchers at the National High Magnetic Field Laboratory, based near Florida State University in Tallahassee, are trying to create. When completed later this year, the pulsed electromagnet, located at the lab’s facility at the Los Alamos National Laboratory, in New Mexico, will reach 100 tesla, the holy grail of magnetic field strength. And in another first, if all goes according to plan it will reach that level-about 67 times as high as a typical MRI-without blowing itself to smithereens.

Tiny Handlike Gripper Could Make It Easier For Doctors

Tiny Handlike Gripper Could Make It Easier For Doctors

A tiny gripper that responds to chemical triggers could be a new tool for surgery.

A tiny handlike gripper that can grasp tissue or cell samples could make it easier for doctors to perform minimally invasive surgery, such as biopsies. The tiny device curls its “fingers” around an object when triggered chemically, and it can be moved around remotely with a magnet.

Mouth Becomes Virtual PC For Disabled

Mouth Becomes Virtual PC For Disabled 

When we think of the human tongue, we think of a piece of human flesh that serves a lot of purposes, whether it is tasting food, cleaning our lips and mouth, kissing, swallowing and much more. And now, Georgia Tech scientists have come up with a breakthrough technology that is going to add yet another task to the already busy tongue.

Cattle Shown to Magnetically Align to North and South

Cattle Shown to Magnetically Align to North and South

Set your compasses to “Bovine North”

Have you ever noticed that herds of grazing animals all face the same way? Images from Google Earth have confirmed that cattle tend to align their bodies in a north-south direction. Wild deer also display this behavior – a phenomenon that has apparently gone unnoticed by herdsmen and hunters for thousands of years.
