General Science / How does a fushigi ball work?
« on: 13/10/2010 09:55:16 »
You control it actively through hand motions, by a technique known as 'contact juggling'. What makes the illusion work is that the ball is a sphere that looks the same no matter what the angle.

The Environment / Is there any risk living under power lines?
« on: 13/10/2010 09:04:13 »
Hi karen,
there are no known health risks that have been conclusively demonstrated to be caused by living near high-voltage power lines. But science is unable to prove a negative, including whether low-level EMFs are completely risk free. Most scientists believe that exposure to the low-level EMFs near power lines is safe, but some scientists continue research to look for possible health risks associated with these fields. If there are any risks such as cancer associated with living near power lines, then it is clear that those risks are small.
