And this doesn't just happen at congested intersections, it happens everywhere. Now I complain when my brother pulls up practically on the bumper of the car in front at a light, but a couple feet is usually the norm. A car length and a half is STUPID!
Mood necklaces or rings usually contain a chemical that changes color with heat (example cold to warmer black, purple, blue, green, reddish). They then usually have a pamphlet saying what the colors mean.
If you are referring to the ring of light sometimes seen around the Moon, then it is called a halo and is a result of moonlight reflecting and refracting in tiny ice crystals located in clouds or the upper atmosphere.here is no giant ring around the moon, but if there was one it would simply be called a 'ring'. A ring is made up of tiny shards of dust and rocks orbiting around a body. who ever typed the above is a dork because i just saw the ring around the moon and came in to look it up!
