ABS speed sensor removal and replacement. Learn how to replace anti-lock brake sensors in this free video on car maintenance.
As a yoga practitioner you must be unafraid to bend your body like a German pretzel into all matter of formations, forgoing that bitter mistress named gravity and find your own center of balance instead. Once you're an advanced yogi you can do such crazy poses as balancing your entire body at a 45 degree incline on just your two hands.
Don't even attempt this exercise if you're not trusting of gravity (and have amazing core balance). Combining one-armed push-ups with chest bounces from the stability ball, the exercise is dependent on your core strength and trust that the ball won't fly away as you come down.
In this clip, learn how to perform the "Amazing Red Bull" trick. You will show your audience a full can of Red Bull and pour a bit out to prove it.

Trying to stack nails above the balance point will raise the CG and make the structure unstable. Here's how you can lower the CG to make a very stable structure and impress your friends.
We've all played with bubbles as kids, but I think most would agree that they're not exactly the most functional of objects. An international team of researchers made up of Yoichi Ochiai, Alexis Oyama and Keisuke Toyoshima wants to change that. They've figured out how to project both 2D and 3D images onto a micro membrane (soap bubble) using ultrasonic sound waves and a standard projector. The bubble is made of a solution of sugar, glycerin, soap, surfactant, water and milk. The glycerin and ...

More than 100 missions targeted at Earth's moon have been launched by space explorers since the late-1950s. NASA landed a total of 12 men on the lunar surface, collecting more than 800 pounds of moon rocks and lunar soil samples. But still, the moon remains a mystery, especially its formation. NASA's new mission aims to find out exactly how the moon came to be with the Gravity Recovery and Interior Laboratory, or GRAIL, part of NASA's Discovery Program.
With severed, angled gaps in three out of four legs, it looks like the work of a chainsaw-wielding maniac. But those gaps are clean cut and without blood, despite the redness of the slices, and definitely not the work of Leatherface.

This video is about fixing self-closing doors. Doors close by themselves when they're not hung plumb, and gravity closes the door. The solution is to remove the hinge-pins and to roughen the bottom of the hinge-pins to create friction, keeping the door open. One removes the hinge-pin with a hammer and small screwdriver. Tap the bottom of the hinge-pin against a cinder block or rough, hard surface. If using this "friction-ized" hinge-pin does not solve your problem, try repeating this process ...
In this tutorial the author explains the concept of Newton's Second Law of motion which states that force is equal to mass times acceleration. So the equation to compute force F is F = m * a, where m is the mass of the body and a is the acceleration produced by the force on that body. He explains that even our weight is our mass times the gravity. So now he explains that mass of a body is constant and only our weight changes depending up on the situation we are in. If you want a clear underst...
